The Azores ( /əˈzɔːrz/ ə-ZORZ, also US: /ˈzɔːrz/ AY-zorz; [5] [6] [7] [8] Portuguese : Açores [ɐˈsoɾɨʃ] ), officially the Autonomous Region of the Azores (Região Autónoma dos Açores), is one of the two autonomous regions of Portugal (along with Madeira). It is an archipelago composed of nine volcanic islands in the North Atlantic Ocean about 1,360 km (850 mi) west of continental Portugal, about 1,643 km (1,021 mi) west of Lisbon, in continental Portugal, about 1,507 km (936 mi) northwest of Morocco, and about 1,925 km (1,196 mi) southeast of Newfoundland, Canada.

American English Set of dialects of the English language spoken in the United States

American English, sometimes called United States English or U.S. English, is the set of varieties of the English language native to the United States. American English is considered one of the most influential dialects of English globally, including on other varieties of English.

Portuguese language Romance language that originated in Portugal

Portuguese is a Western Romance language originating in the Iberian Peninsula. It is the sole official language of Portugal, Brazil, Cape Verde, Guinea-Bissau, Mozambique, Angola, and São Tomé and Príncipe. It also has co-official language status in East Timor, Equatorial Guinea and Macau in China. As the result of expansion during colonial times, a cultural presence of Portuguese and Portuguese creole speakers are also found in Goa, Daman and Diu in India; in Batticaloa on the east coast of Sri Lanka; in the Indonesian island of Flores; in the Malacca state of Malaysia; and the ABC islands in the Caribbean where Papiamento is spoken, while Cape Verdean Creole is the most widely spoken Portuguese-based Creole. A Portuguese-speaking person or nation is referred to as "Lusophone" (Lusófono).


Its main industries are agriculture, dairy farming, livestock, fishing, and tourism, which is becoming the major service activity in the region. In addition, the government of the Azores employs a large percentage of the population directly or indirectly in the service and tertiary sectors. The main city of the Azores is Ponta Delgada.

Dairy farming class of agricultural, or an animal husbandry, enterprise

Dairy farming is a class of agriculture for long-term production of milk, which is processed for eventual sale of a dairy product.

Fishing in Portugal

Fishing is a major economic activity in Portugal. The country has a long tradition in the sector, and is among the countries in the world with the highest fish consumption per capita. Roman ruins of fish processing facilities were found across the Portuguese coast. Fish has been an important staple for the entire Portuguese population, at least since the Portuguese Age of Discovery.

Tourism in Portugal

Tourism in Portugal serves millions of international and domestic tourists. Tourists visit to see cities, historic landmarks, enjoy beaches, or religious sites. In 2017, Portugal had 23 million visitors. The most popular destinations were Lisbon, Porto, Fatima, the Portuguese Riviera and the Algarve. The most popular with internationals were Lisbon, the Algarve and Northern Portugal. National tourists prefer Northern Portugal, followed by Central Portugal and the Algarve.

There are nine major Azorean islands and an islet cluster, in three main groups. These are Flores and Corvo, to the west; Graciosa, Terceira, São Jorge, Pico, and Faial in the centre; and São Miguel, Santa Maria, and the Formigas Reef to the east. They extend for more than 600 km (370 mi) and lie in a northwest-southeast direction.

Corvo Island protected area in Portugal

Corvo Island, literally the Island of the Crow, is the smallest and the northernmost island of the Azores archipelago and the northernmost in Macaronesia, has a population of approximately 468 inhabitants constituting the smallest single municipality in the Azores and in Portugal, and lies within the North American Plate.

Graciosa island of Azores, Portugal

Graciosa Island is referred to as the White Island, the northernmost of the Central Group of islands in the Azores. The ovular Portuguese island has an area of 60.65 square kilometres, a length of 10 kilometres and a width of 7 kilometres. It is a volcanic island, dominated by a 1.6-kilometre-wide (1.0-mile) central caldera located in the southeast.

São Jorge Island island of the Azores, Portugal

São Jorge is an island situated in the central group of the Azores archipelago and part of the autonomous region of Portugal. Separated from its nearest neighbors by the 15 kilometres (9.3 mi) Pico-São Jorge Channel, the central group is often referred colloquially as part of the Triangulo ("Triangle") group or just "The Triangle". São Jorge is a relatively long thin island with tall cliffs, whose 9500 inhabitants are concentrated on various geological debris fields (fajãs) along the north and south coasts; from east to west, the island is 53 kilometres (33 mi) long and, north to south, 8 kilometres (5.0 mi) wide: its area is 237.59 square kilometres (91.73 sq mi).

All the islands have volcanic origins, although some, such as Santa Maria, have had no recorded activity since the islands were settled. Mount Pico, on the island of Pico, is the highest point in Portugal, at 2,351 m (7,713 ft). If measured from their base at the bottom of the ocean to their peaks, which thrust high above the surface of the Atlantic, the Azores are actually some of the tallest mountains on the planet.

Santa Maria Island Island in Azores, Portugal

Santa Maria, Portuguese for Saint Mary, is an island located in the eastern group of the Azores archipelago and the southernmost island in the Azores. The island is primarily known for its white sand beaches, distinctive chimneys, and dry warm weather.

Mount Pico stratovolcano and the highest mountain of Portugal

Mount Pico is a stratovolcano located on Pico Island, in the mid-Atlantic archipelago of the Azores. It is the highest mountain of Portugal, at 2,351 metres (7,713 ft) above sea level, and is one of the highest Atlantic mountains; it is more than twice the elevation of any other peak in the Azores.

Pico Island Island in Azores, Portugal

Pico Island, is an island in the Central Group of the Portuguese Azores. The landscape features an eponymous volcano, Ponta do Pico, which is the highest mountain in Portugal, the Azores, and the highest elevation of the Mid-Atlantic Ridge. In the tradition of the Portuguese poet, Raul Brandão, Pico is referred to as the Ilha Preta, for its black volcanic earth, responsible for its UNESCO-designated historical vineyards that allowed the development of the island.

The climate of the Azores is very mild for such a northerly location, being influenced by its distance from the continents and by the passing Gulf Stream. Due to the marine influence, temperatures remain mild year-round. Daytime temperatures normally fluctuate between 16 °C (61 °F) and 25 °C (77 °F) depending on season. [9] [10] Temperatures above 30 °C (86 °F) or below 3 °C (37 °F) are unknown in the major population centres. It is also generally wet and cloudy.

Gulf Stream A warm, swift Atlantic current that originates in the Gulf of Mexico flows around the tip of Florida, along the east coast of the United States before crossing the Atlantic Ocean

The Gulf Stream, together with its northern extension the North Atlantic Drift, is a warm and swift Atlantic ocean current that originates in the Gulf of Mexico and stretches to the tip of Florida, and follows the eastern coastlines of the United States and Newfoundland before crossing the Atlantic Ocean. The process of western intensification causes the Gulf Stream to be a northward accelerating current off the east coast of North America. At about 40°0′N30°0′W, it splits in two, with the northern stream, the North Atlantic Drift, crossing to Northern Europe and the southern stream, the Canary Current, recirculating off West Africa.

The culture, dialect, cuisine, and traditions of the Azorean islands vary considerably, because these once-uninhabited and remote islands were settled sporadically over a span of two centuries.


A small number of alleged hypogea, earthen structures carved into rocks that were used for burials, have been identified on the islands of Corvo, Santa Maria and Terceira by Portuguese archaeologist Nuno Ribeiro, who speculated that they might date back 2000 years, implying a human presence on the island before the Portuguese. [11] These kinds of structures have been used in the Azores to store cereals, however, and suggestions by Ribeiro that they might be burial sites are unconfirmed. Detailed examination and dating to authenticate the validity of these speculations is lacking. [12] It is unclear whether these structures are natural or man-made and whether they predate the 15th-century Portuguese colonization of the Azores. Therefore, clear confirmation of a pre-Portuguese human presence in the archipelago has not yet been published.

European discovery

The islands were known in the fourteenth century, and parts of them appear in the Catalan Atlas. In 1427, a captain sailing for Prince Henry the Navigator, possibly Gonçalo Velho, may have rediscovered the Azores, but this is not certain. In Thomas Ashe's 1813 work, A History of the Azores, [13] the author identified a Fleming, Joshua Vander Berg of Bruges, who made landfall in the archipelago during a storm on his way to Lisbon. [13] He stated that the Portuguese explored the area and claimed it for Portugal. [13] Other stories note the discovery of the first islands (São Miguel Island, Santa Maria Island and Terceira Island) by sailors in the service of Henry the Navigator, although there are few documents to support the claims.

Although it is commonly said that the archipelago received its name from the goshawk (açor in Portuguese), a common bird at the time of discovery, it is unlikely that the bird nested or hunted on the islands.

There were no large animals on Santa Maria, so after its discovery and before settlement began, sheep were let loose on the island to supply future settlers with food. Settlement did not take place right away, however. There was not much interest among the Portuguese people to live in an isolated archipelago so far from civilization. Gonçalo Velho Cabral patiently gathered resources and settlers for the next three years (1433–1436), however, and sailed to establish colonies first on Santa Maria and then on São Miguel.

Settlers cleared bush and rocks to plant crops—grain, grape vines, sugar cane, and other plants suitable for local use and of commercial value. They brought domesticated animals, such as chickens, rabbits, cattle, sheep, goats, and pigs and built houses and established villages.

The archipelago was largely settled from mainland Portugal. Portuguese settlers came from the provinces of Algarve, Minho, Alentejo and Ribatejo as well as Madeira. São Miguel was first settled in 1449, the settlers – mainly from the Estremadura, Alto Alentejo and Algarve areas of mainland Portugal, under the command of Gonçalo Velho Cabral – landed at the site of modern-day Povoação. Many early settlers were Portuguese Sephardic Jews who fled the pressures of inquisition in mainland Portugal. In 1522, Vila Franca do Campo, then the capital of the island, was devastated by an earthquake and landslide that killed about 5,000 people, and the capital was moved to Ponta Delgada. The town of Vila Franca do Campo was rebuilt on the original site and today is a thriving fishing and yachting port. Ponta Delgada received its city status in 1546. From the first settlement, the pioneers applied themselves to agriculture and by the 15th century Graciosa exported wheat, barley, wine and brandy. The goods were sent to Terceira largely because of the proximity of the island.

During the 18th and 19th centuries, Graciosa was host to many prominent figures, including Chateaubriand, the French writer who passed through upon his escape to America during the French revolution; Almeida Garrett, the Portuguese poet who visited an uncle and wrote some poetry while there; and Prince Albert of Monaco, the 19th century oceanographer who led several expeditions in the waters of the Azores. He arrived on his yacht Hirondelle, and visited the furna da caldeira, the noted hot springs grotto. In 1869, the author Mark Twain published The Innocents Abroad , a travel book, where he described his time in the Azores.

The first reference to the island of São Jorge was made in 1439 but the actual date of discovery is unknown. In 1443 the island was already inhabited but active settlement only began with the arrival of the noble Flemish native Wilhelm Van der Haegen. Arriving at Topo, where he lived and died, he became known as Guilherme da Silveira to the islanders. João Vaz Corte-Real received the captaincy of the island in 1483. Velas became a town before the end of the 15th century. By 1490, there were 2,000 Flemings living in the islands of Terceira, Pico, Faial, São Jorge and Flores. Because there was such a large Flemish settlement, the Azores became known as the Flemish Islands or the Isles of Flanders. Prince Henry the Navigator was responsible for this settlement. His sister, Isabel, was married to Duke Philip of Burgundy of which Flanders was a part. There was a revolt against Philip's rule and disease and hunger became rampant. Isabel appealed to Henry to allow some of the unruly Flemings to settle in the Azores. He granted this and supplied them with the necessary transportation and goods.

The settlement of the then-unoccupied islands started in 1439 with people mainly from the continental provinces of Algarve and Alentejo. In 1583, Philip II of Spain, as king of Portugal, sent his fleet to clear the Azores of a combined multinational force of adventurers, mercenaries, volunteers and soldiers who were attempting to establish the Azores as a staging post for a rival pretender to the Portuguese throne. Following the success of his fleet at the Battle of Ponta Delgada captured enemies were hanged from yardarms, as they were considered pirates by Philip II. Opponents receiving the news variously portrayed Philip II as a despot or "Black Legend"; the sort of insult widely made against contemporary monarchs engaged in aggressive empire building and the European Wars of Religion. An English raid of the Azores in 1589 successfully plundered some harbouring ships and islands; a repeat eight years later, the Islands Voyage, failed. Spain held the Azores under the "Babylonian captivity" of 1580–1642. In the late 16th century, the Azores and Madeira began to face problems of overpopulation. Spawning from that particular economic problem, some of the people began to emigrate to Brazil. [14]

Iberian Union

Following the death of Henry, the Cardinal-King of Portugal the nation fell into a dynastic crisis with various pretenders to the Crown of Portugal. [15] Following his proclamation in Santarém, António, Prior of Crato was acclaimed in the Azores in 1580 (through his envoy António da Costa), but was expelled from the continent following the Battle of Alcântara. [15] Yet, through the administration of Cipriano de Figueiredo, governor of Terceira (who continued to govern Terceira in the name of ill-fated, former-king Sebastian of Portugal), the Azoreans resisted attempts to conquer the islands (including specifically at the Battle of Salga). [16] It was Figueiredo and Violante do Canto who helped organize a resistance on Terceira that influenced some of the response of the other islands, even as internal politics and support for Philip's faction increased on the other islands (including specifically on São Miguel, where the Gonçalvez da Câmara family supported the Spanish pretender). [16]

The Azores were the last part of the Portuguese Empire to resist Philip's reign over Portugal (Macau resisted any official recognition) and were returned to Portuguese control with the end of the Iberian Union in 1640, not by the professional military, who were used in the Restoration War in the mainland, but by local people attacking a fortified Castilian garrison.

Liberal Wars

The Portuguese Civil War (1828–1834) had strong repercussions in the Azores. In 1829, in Praia da Vitória, the Liberals won over the absolutists, making Terceira Island the main headquarters of the new Portuguese regime and also where the Council of Regency (Conselho de Regência) of Maria II of Portugal was established.

Beginning in 1868, Portugal issued its stamps overprinted with "AÇORES" for use in the islands. Between 1892 and 1906, it also issued separate stamps for the three administrative districts of the time.

From 1836 to 1976, the archipelago was divided into three districts, equivalent (except in area) to those in the Portuguese mainland. The division was arbitrary, and did not follow the natural island groups, rather reflecting the location of each district capital on the three main cities (none of which were on the western group).

Modern times

In 1931 the Azores (together with Madeira and Portuguese Guinea) revolted against the Ditadura Nacional and were held briefly by military rebels. [17]

In 1943, during World War II, the Portuguese ruler António de Oliveira Salazar leased air and naval bases in the Azores to Great Britain. [18] The occupation of these facilities in October 1943 was codenamed Operation Alacrity by the British. [19]

This was a key turning point in the Battle of the Atlantic, enabling the Royal Air Force, the U.S. Army Air Forces, and the U.S. Navy to provide aerial coverage in the Mid-Atlantic gap. This helped them to protect convoys and to hunt hostile German U-boats.

In 1944, the U.S. constructed a small and short-lived air base on the island of Santa Maria. In 1945, a new base was constructed on the island of Terceira, and it is named Lajes Field. This air base is in an area called Lajes, a broad, flat sea terrace that had been a large farm. Lajes Field is a plateau rising out of the sea on the northeast corner of the island. This air base is a joint American and Portuguese venture. Lajes Field continues to support the American and Portuguese Armed Forces. During the Cold War, U.S. Navy P-3 Orion antisubmarine warfare squadrons patrolled the North Atlantic Ocean for Soviet Navy submarines and surface warships. Since its opening, Lajes Field has been used for refuelling American cargo planes bound for Europe, Africa, and the Middle East. The U.S. Navy keeps a small squadron of its ships at the harbor of Praia da Vitória, three kilometres (1.9 miles) southeast of Lajes Field.

The airfield also has a small commercial terminal handling scheduled and chartered passenger flights from the other islands in the Azores, Europe, Africa, and North America.

In 1976, the Azores became the Autonomous Region of the Azores (Região Autónoma dos Açores), one of the autonomous regions of Portugal, and the subdistricts of the Azores were eliminated.

In 2003, the Azores saw international attention when United States President George W. Bush, British Prime Minister Tony Blair and Spanish Prime Minister José María Aznar and Portuguese Prime Minister José Manuel Durão Barroso held a summit there days before the commencement of the Iraq War. [20]

The archipelago of the Azores is located in the middle of the northern hemisphere of the Atlantic Ocean and extends along a west-northwest to east-southeast orientation (between 36.5°–40° North latitudes and 24.5°–31.5° West longitudes) in an area approximately 600 kilometres (373 miles) wide. The islands of the Azores emerged from what is called the Azores Plateau, a 5.8 million km2 region that is morphologically accented by a depth of 2,000 metres (6,600 feet). [21] [22]

From a geostructural perspective the Azores is located above an active triple junction between three of the world's large tectonic plates (the North American Plate, the Eurasian Plate and the African Plate), [22] a condition that has translated into the existence of many faults and fractures in this region of the Atlantic. [23] The westernmost islands of the archipelago (Corvo and Flores) are located in the North American Plate, while the remaining islands are located within the boundary that divides the Eurasian and African Plates.

The principal tectonic structures that exist in the region of the Azores are the Mid-Atlantic Ridge, the Terceira Rift, the Azores Fracture Zone and the Glória Fault. [22] The Mid-Atlantic Ridge is the main frontier between the American Plate and the African-Eurasian Plates that crosses the Azores Plateau between the islands of Flores and Faial from north to south then to the southwest; it is an extensive form crossed by many transform faults running perpendicular to its north-south orientation, that is seismically active and susceptible to volcanism. The Terceira Rift is a system of fractures that extends from the Mid-Atlantic Ridge to the Glória Fault that represents the main frontier between the Eurasian and African Plates. It is defined by a line of submarine volcanoes and island mounts that extend northwest to southeast for about 550 kilometres (342 miles), from the area west of Graciosa until the islets of the Formigas, that includes the islands of Graciosa, Terceira and São Miguel. Its northwest limit connects to the Mid-Atlantic Ridge, while the southeast section intersects the Gloria Fault southeast of the island of Santa Maria. The Azores Fracture Zone extends from the Glória Fault and encompasses a relatively inactive area to the south of the islands of the Central and Eastern groups north to the Terceira Rift, along a 45° angle. The Glória Fault, for its part, extends 800 kilometres (497 miles) along a linear line from the Azores to the Azores–Gibraltar Transform Fault. [24]

The island's volcanism is associated with the rifting along the Azores Triple Junction; the spread of the crust along the existing faults and fractures has produced many of the active volcanic and seismic events, [25] while supported by buoyant upwelling in the deeper mantle, some associate with an Azores hotspot. [26] Most of the volcanic activity has centered, primarily, along the Terceira Rift. From the beginning of the island's settlement, around the 15th century, there have been 28 registered volcanic eruptions (15 terrestrial and 13 submarine). The last significant volcanic eruption, the Capelinhos volcano (Vulcão dos Capelinhos), occurred off the coast of the island of Faial in 1957; the most recent volcanic activity occurred in the seamounts and submarine volcanoes off the coast of Serreta and in the Pico-São Jorge Channel. [27] The islands have many examples of volcano-built geomorphology including many of the caves and subterranean lava tubes (such as the Gruta das Torres, Algar do Carvão, Gruta do Natal, Gruta das Cinco Ribeiras), the coastal lava fields (like the coast of Feteiras, Faial, the Mistério of Prainha or São João on Pico Island) in addition to the currently inactive cones in central São Miguel Island, the aforementioned Capelinhos on Faial, the volcanic complexes of Terceira or Plinian caldeira of Corvo Island.

The islands of the archipelago were formed through volcanic and seismic activity during the Neogene Period; the first embryonic surfaces started to appear in the waters of Santa Maria during the Miocene epoch (from circa 8 million years ago). The sequence of the island formation has been generally characterized as: Santa Maria (8.12 Ma), São Miguel (4.1 Ma), Terceira (3.52 Ma), Graciosa (2.5 Ma), Flores (2.16 Ma), Faial (0.7 Ma), São Jorge (0.55 Ma), Corvo (0.7 Ma) and the youngest, Pico (0.27 Ma). [28] Although all islands have experienced volcanism during their geological history, within recorded "human settlement" history the islands of Santa Maria, Graciosa, Flores, and Corvo have not experienced any volcanic eruptions; in addition to active fumaroles and hot-springs, the remaining islands have had sporadic eruptions since the 14th century. Apart from the Capelinhos volcano in 1957–58, the last recorded instance of "island formation" occurred off the coast of São Miguel, when the island of Sabrina was briefly formed.

Owing to its geodynamic environment, the region has been center of intense seismic activity, particularly along its tectonic boundaries on the Mid-Atlantic Ridge and Terceira Rift. Seismic events although frequent, usually tectonic or vulco-tectonic in nature, but in general low to medium intensities, occasionally punctuated by events of level 5 or greater on the Richter magnitude scale. [29] [30] The most severe earthquake was registered in 1757, near Calheta on the island of São Jorge, which exceeded 7 on the Richter magnitude scale. In comparison, the 1522 earthquake that was mentioned by historian Gaspar Frutuoso measured 6.8, but its effects were judged to be X (Extreme) on the Mercalli intensity scale, [31] and was responsible for the destruction of Vila Franca do Campo and landslides that may have killed more than 5,000 of the inhabitants.

The nine islands that compose the archipelago occupy a surface area of 2,346 km2 (906 sq mi), that includes both the main islands and many islets located in their vicinities. Each of the islands has its own distinct geomorphological characteristics that make them unique: Corvo (the smallest island) is a crater of a major Plinian eruption; Flores (its neighbor on the North American Plate) is a rugged island carved by many valleys and escarpments; Faial characterized for its shield volcano and caldera (Cabeço Gordo); Pico, is the highest point, at 2,351 meters (7,713 ft), in the Azores and continental Portugal; Graciosa is known for its active Furnas do Enxofre and mixture of volcanic cones and plains; São Jorge is a long slender island, formed from fissural eruptions over thousands of years; Terceira, almost circular, is the location of one of the largest craters in the region; São Miguel is the largest island, and is pitted with many large craters and fields of spatter cones; and Santa Maria, the oldest island, is heavily eroded, being one of the few places to encounter brown sandy beaches in the archipelago. They range in surface area from the largest, São Miguel, at 759 km2 (293 sq mi) to the smallest, Corvo, at approximately 17 km2 (7 sq mi).

These islands can be divided into three recognizable groups located on the Azores Plateau:

In addition, several sub-surface reefs (particularly the Dollabarat on the fringe of the Formigas), banks (specifically the Princess Alice Bank and D. João de Castro Bank, as well as many hydrothermal vents and sea-mounts are monitored by the regional authorities, owing to the complex geotectonic and socioeconomic significance within the economic exclusion zone of the archipelago.

The archipelago lies in the Palearctic ecozone, forming a unique biome that includes the macaronesian subtropical laurissilva, with many endemic species of plants and animals. [32] [33] In total, there are at least 6112 terrestrial species, of which about 411 are endemic. The majority (75%) of these endemics are animals, mostly arthropods and mollusks. New species are found regularly in the Azores (e.g., 30 different new species of land snails were discovered circa 2013 [34] ).

Even though the Azores look very green and sometimes wild, the vegetation has been extremely altered. A great part of it has been wiped out in the past 600 years for its valuable wood (for tools, buildings, boats, fire wood, and so on) and to clear land for agriculture. As a result, it is estimated that more than half of insects on the Graciosa island have disappeared or will become extinct. [32] Many cultivated places (which are traditionally dedicated to pasture or to growing colocasia, potatoes, maize and other crops) have now been abandoned, especially as a result of emigration. Consequently, some invasive plants have filled these deserted and disturbed lands. Hydrangeas are another potential pest, but their threat is less serious. Notwithstanding the fact that hydrangeas were introduced from America or Asia, some locals consider them a symbol of the archipelago and propagate them along roadsides, helping the plants to escape into the wild. Cryptomeria , the Japanese cedar, is a conifer extensively grown for its timber. The two most common of these alien species are Pittosporum undulatum and Acacia melanoxylon . They are usually restricted to ancient agricultural land and only rarely penetrate into undisturbed native vegetation.

Reforestation efforts with native laurissilva vegetation have been done successfully in many parts of the Azores. [35] [36] [37]

The Azores has at least two endemic bird species. The Azores bullfinch, or Priolo, is restricted to remnant laurisilva forest in the mountains at the eastern end of São Miguel [38] and is classified by BirdLife International as endangered. Monteiro's storm-petrel, described to science as recently as 2008, is known to breed in just two locations in the islands, but may occur more widely. An extinct species of owl, the São Miguel scops owl, has also recently been described, which probably became extinct after human settlement due to habitat destruction and the introduction of alien species. [39] The Azores also has an endemic bat, the Azores noctule, which is unusual in regularly feeding during the day.

The islets of the Formigas (the Portuguese word for "ants"), including the area known as the Dollabarat Reef, have a rich environment of maritime species, such as black coral and manta rays, different species of sharks, whales, and sea turtles. On São Miguel there are notable micro-habitats formed by hot springs that host extremophile microorganisms. [40]

17 new marine reserves (with special conservation status) were added to the Azorean Marine Park (which covers currently around 900.000 km2) [41]

The archipelago is spread out in the area between 37° N and the parallels of latitude that pass through the Lisbon area (38° 43' / 38° 55' N), giving it a generally tepid, oceanic, subtropical climate, with mild annual oscillations. Daily maximum temperatures usually range between 15 and 25 °C (59 and 77 °F). The average annual rainfall increases from east to west, ranging from 700 to 1600 millimetres (27.6–63 in) in the east and reaching 6,300 millimetres (250 in) on Mount Pico, [42] the highest Portuguese mountain at 2,351 m (7,713 ft). The Azores High, an area of high atmospheric pressure, is named after the islands. Under the Köppen climate classification, there are different local climates, one of which is "dry-summer subtropical", often referred to as "Mediterranean". Rivas Martinez data presents several different bioclimatic zones for the Azores. [43] Seasonal lag is extreme in the low-sun half of the year, with December being milder than April in terms of mean temperatures. Azores have the warmest winters in Europe (still within the European continental plate). During summer the lag is somewhat lower, with August being the warmest month. There has never been a frost, snowfall or freeze recorded at sea level on any of the islands. The coldest weather in winter usually comes from northwesterly air masses originating from Labrador in Canada. But because those air masses are modified as they pass across the warmer Atlantic Ocean, temperatures by day even then exceed 10 °C (50 °F).

In addition, the Instituto de Meteorologia has identified the following weather extremes:


The Azores are known for small hurricanes. A total of 14 tropical or subtropical cyclones have affected the region in history. Most of them were either extratropical or tropical storms when they affected the region, although several Category 1 hurricanes have reached the Azores. Only one major hurricane has ever impacted the Azores; Hurricane Ophelia in 2017, at Category 3 intensity. The following storms have impacted the region while at Category 1 strength: Hurricane Fran in 1973, Hurricane Emmy in 1976, Hurricane Gordon in 2006, Hurricane Gordon in 2012 and Hurricane Alex in 2016. Several tropical storms have hit the region, including Tropical Storm Irma in 1978, Hurricane Bonnie in 1992, Hurricane Charley in 1992, Hurricane Erika in 1997, and Hurricane Gaston in 2016. Storms that were extratropical when they impacted the region include Hurricane Tanya in 1995, Tropical Storm Ana in 2003 and Tropical Storm Grace in 2009. In addition, the 2005 Azores subtropical storm affected the region in October 2005.


The Azores are divided into 19 municipalities (concelhos); each municipality is further divided into parishes (freguesias), of which there is a total of 156 in all of the Azores. The municipalities, by island, are:

There are six cities (Portuguese: cidades) in the Azores: Ponta Delgada, Lagoa and Ribeira Grande on the island of São Miguel; Angra do Heroísmo and Praia da Vitória on the island of Terceira, and Horta on Faial. Three of these, Ponta Delgada, Angra and Horta are considered capital/administrative cities to the regional government: homes to the President (Ponta Delgada), the Judiciary (Angra) and the Regional Assembly (Horta). Angra also serves as the ecclesiastical centre of the Roman Catholic Diocese of Angra, the episcopal see of the Azores.

According to the 2011 Census, population in the Azores was 246,746 at a density of 106 inhabitants per square kilometre (270/sq mi).

The Azores were uninhabited when Portuguese navigators arrived in the early 15th century; settlement began in 1439 with migrants from several regions of mainland Portugal and from Madeira. The islands were populated mainly by Portuguese immigrants from the Algarve, Alentejo, and Minho; in an effort to escape the dangers of the Portuguese inquisition on mainland Portugal, however, many Portuguese Sephardic Jews settled on the islands in large numbers. Azorean Jews had surnames such as: Rodrigues, Pacheco, Oliveira, Pereira, Pimentel, Nunes, Mendes, Pinto, Álvares, Henriques, Cardozo, Teixeira, Vasconcelos etc. The islands were also settled by Moorish prisoners, and African slaves from Guinea, Cape Verde and São Tomé; Flemish, French and Galicians also contributed to the initial settlement. Thus the Azorean population received a significant contribution from people with genetic backgrounds other than Portuguese.

The nature of the economy dictated that African slavery never became common in the Azores because they were sent to Brazil and the Caribbean. Only a few remained in the Azores to help with domestic chores, although the islands sometimes served as a waypoint for ships carrying African slaves. [48]

Africans, Moors, Jews, Scots, Germans, Italians, French, Spanish, Flemish and Portuguese all migrated to the Azores. [49]

As in continental Portugal, the most frequent mtDNA haplogroup in the Azores is H (45.2%), followed by U (16.7%), T (10.1%), K (6.5%), pre-HV clades (5.6%) and a smaller African L haplogroups frequency (3.4%) than in Madeira.

Inhabitants of the various islands have DNA of various origins. [50] [51] A minority on the islands has non-European ancestry. [52]


Since the 17th century, many Azoreans have emigrated, mainly to Brazil, Uruguay, the United States and Canada. [53] Rhode Island and Southeastern Massachusetts, especially the cities of New Bedford, Bristol, Barrington, Pawtucket, Central Falls, West Warwick, Hudson, Marlborough, East Providence, River Point, Somerset, Taunton and Fall River have been, and remain, the primary destination for Azorean emigrants. [54] Emigrants from the East coast returned to their homeland and taught the American dory fishing technique to the Portuguese who began catching cod again on the Grand Bank in the 19th century. [55]

Northern California was the final destination for many of the Massachusetts immigrants who then moved on to the San Joaquin Valley, especially the city of Turlock, just south of Modesto. In the late 1800s many Azoreans emigrated to the Hawaiian islands. The tuna fishing industry drew a significant number of Azoreans to the Point Loma neighborhood of San Diego, in Southern California. [56] From 1921 to 1977, about 250,000 Azoreans immigrated to Rhode Island and Massachusetts. [57]

Many Azoreans also moved to Bermuda and Hawaii (Portuguese immigration to Hawaii). [58] Florianópolis and Porto Alegre in the Southern Region of Brazil were founded by Azoreans, who accounted for over half of Rio Grande do Sul and Santa Catarina's population in the late 18th century. [59] As late as 1960 mass immigration currents were registered to Brazil, and many were from the Azores. [58]

Since 1976, the Azores is an autonomous region integrated within the framework of the Portuguese Republic. It has its own government and autonomous legislature within its own political-administrative statute and organic law. Its governmental organs include: the Legislative Assembly, a unicameral parliament composed of 52 elected deputies, elected by universal suffrage for a four-year term; the Regional Government and Presidency, with parliamentary legitimacy, composed of a President, a Vice-President and seven Regional Secretaries responsible for day-to-day operations. It is represented in the Council of Ministers by a representative appointed by the President of the Republic, which was created during the revision of the constitution of 2004 (which, among other things, removed the older Portuguese representative that was appointed by the President of the Republic, beholden to the Council of State and coincident with the President).

Since becoming a Portuguese autonomous region, the executive branch of the regional authority has been located in Ponta Delgada, the legislative branch in Horta, and the judicial branch in Angra do Heroísmo.

The islands of the archipelago do not have independent status in law, except in electoral law and are governed by 19 municipalities that subdivide the islands. In addition, until the administrative reform of the 19th century, the following civil parishes had municipal standing: Topo (today integrated into the municipality of Calheta, São Jorge); Praia (today integrated into municipality of Santa Cruz da Graciosa); São Sebastião (today an integral part of the municipality of Angra do Heroísmo); Capelas (now part of the municipality of Ponta Delgada); and Água de Pau (now a civil parish in the municipality of Lagoa). These civil parishes still retain their titles of "vila" in name only; the populations of Capelas and neighbouring parish still protest the change and promote the restoration of their status. The municipalities are further subdivided into several civil parishes, with the exception of Corvo (the only municipality by law without a civil parish, owing to its size).

Azorean politics is dominated by the two largest Portuguese political parties, the Social Democratic Party (PSD) and the Socialist Party (PS), the latter holding a majority in the Regional Legislative Assembly. The Democratic and Social Center / People's Party (CDS/PP), the Left Bloc (BE), the Unitarian Democratic Coalition (CDU) and the People's Monarchist Party (PPM) are also represented in the local parliament. Currently, as of the 2008 Regional Elections, the Socialist Party (PS) and its leader, Carlos César have a plurality of the seats in the Assembly, and operate the Regional Government. Although the PS dominates the regional politics, the PSD is traditionally popular in city and town council elections.

European Union

As part of Portugal, the Azores are in the European Union and Schengen Area. They are also in the European Union Customs Union and VAT area, [60] but levy a lower rate of VAT than applies on the mainland. The Azores, like Madeira and the Canary Islands, are among member state territories with special status, as one of the designated "Outermost Regions".



Each of the nine islands has an airport, [61] although the majority are airfields rather than airports. The commercial terminals in Ponta Delgada, Horta, Vila do Porto and Santa Cruz das Flores are operated by ANA – Aeroportos de Portugal, a public entity that oversees the operations of airports across Portugal. The remaining, except for Lajes Field, are operated by the Regional Government. Lajes is a military airbase, as well as a commercial airport, and is operated by the Portuguese Armed Forces in conjunction with the United States.

The airports are:

Marine transport

The Azores has had a long history of water transport to overcome distances and establish inter-community contacts and trade. Consequently, the shipbuilding industry developed in many islands, from small fishing boats, to whaling sloops to larger passenger services. [62] Passenger traffic to the main islands (São Miguel, Santa Maria, Terceira and Faial) began in the 17th century, and between the 18th–19th century, the Pico Yacht controlled the lucrative summer traffic season. [62]

After 1871, the Insulana Shipping Company was the only entity responsible for regular traffic between the islands (except Corvo), Madeira and the United States. [62] Yet, cargo and passenger transportation ceased in the 1970s, and the ships were sold or converted into tuna fishing boats. For the next 20 years, commercial maritime service between the islands ceased (except between Faial-Pico and Lajes das Flores-Vila do Corvo). [62]

Transmaçor (Transportes Marítimos Açorianos, Lda.) was founded on 22 December 1987, resulting from the fusion of Empresa das Lanchas do Pico, Ld, owners of the ships Espalamaca and Calheta (ships that had travelled the canal between Faial and Pico for several years); Empresa Açoreana de Transportes Marítimos, Lda, which operated the ship Terra Alta; and Transcanal (Transportes Marítimos do Canal, Lda.) operator the traditional boats Picaroto and Manuel José. [63] [64] In the Central Group, the shipping company operates four to six time daily connections between Horta and Madalena throughout the year, using its small fleet of ships ( Cruzeiro das Ilhas , Cruzeiro do Canal , Expresso das Ilhas and Expresso do Triângulo), in addition to inter-island connections between Faial, Pico, São Jorge and Terceira during the summer months. [63]

Meanwhile, new initiatives began in the late 1990s: the catamaran Iapetos began services, followed by Lady of Mann and Golfinho Azul (chartered by Açorline). [62]

In 2005, Atlânticoline was established, providing services with the ships Ilha Azul and Express Santorini, later adding the Viking in 2009. [62] In 2009, Atlanticoline was involved in a controversial rejection of a 750-passenger, 150-vehicle ship ordered from the Estaleiros de Viana do Castelo (Viana do Castelo Shipyards). [65] The Atlantida, a 50 million Euro cruiser (as part of a two-ship deal with the other named Anticiclone) was rejected in 2009 by Atlanticoline for the under-performance of the power-plant. [65] Although it would only result in a five-minute delay between islands, the public company rejected the ship, and the contract was broken over the builder's inability to deliver the required ship on time. [65] While, the ship was being shopped to other interested parties (Hugo Chávez once considered purchasing the ferryboat in 2010), no interested buyers appeared, and ENVC decided to cede the Atlantida to Atlânticoline as part of the latter's open international competition to charter two ships in 2012. [65]

On 20 June 2011, the Regional Government announced that it would purchase 60% of Transmaçor, equivalent to 500,000 Euro of the company's capital. [66] With this transaction the Autonomous government of the Azores ceded control, of which it once had 88% of the capital. [66] The signed memorandum of understanding concluded negotiations between the various parties involved, under which the liability of Transmaçor (worth a total of 8 million Euro) was divided equally between the Region and businessman José Almeida, who is now the holder of a majority stake in the company. [66]

Similarly, the Regional Government approved the consolidation of the three individual port authorities (Administração dos Portos do Triângulo e Grupo Ocidental, Administração dos Portos da Terceira e Graciosa and the Administração dos Portos das Ilhas de São Miguel e Santa Maria) and regional Portos dos Açores into one entity that resulted in a 2.2 million Euro cost savings, in addition to a reduction from 11 to three administrators. [67]

Azoreans have developed their own distinct regional identity and cultural traits, from a combination of continental Portuguese customs brought by various waves of immigration and local political and environmental factors.

Religious festivals, patron saints and traditional holidays mark the Azorean calendar. The most important religious events are tied with the festivals associated with the cult of the Holy Spirit, commonly referred to as the festivals of the Holy Spirit (or Espírito Santo), rooted in millenarian dogma and held on all islands from May to September. These festivals are very important to the Azorean people, who are primarily Roman Catholic, and combine religious rituals with processions celebrating the benevolence and egalitarianism of neighbours. These events are centred around treatros or impérios, small buildings that host the meals, adoration and charity of the participants, and used to store the artefacts associated with the events. On Terceira, for example, these impérios have grown into ornate buildings painted and cared for by the local brotherhoods in their respective parishes. The events focus on the members of local parishes, not tourists, but all are welcome, as sharing is one of the main principles of the festivals. Some limited events focus on tourists, including a public event that the city government of Ponta Delgada on the island of São Miguel holds, which attracts visitors and locals.

Another event, the Festival of the Lord Holy Christ of the Miracles (or Senhor Santo Cristo dos Milagres) in Ponta Delgada on the island of São Miguel, is the largest individual religious event in the Azores, and takes place on Rogation Sunday. Pilgrims from within the Portuguese diaspora normally travel to Ponta Delgada to participate in an afternoon procession behind the image of Christ along the flower-decorated streets of the city. Although the solemn procession is only held on one day, the events of the Festival of Senhor Santo Cristo occur over a period of a week and involve a ritual of moving the image between the main church and convent nightly, ultimately culminating in the procession, which is televised within the Azores and to the Portuguese diaspora. The Sanjoaninas Festivities in Angra do Heroísmo on Terceira are held in June honoring Saint Anthony, Saint Peter and Saint John the Baptist, in a large religious celebration.

The festival of Our Lady of Lourdes (or Nossa Senhora de Lourdes), patron saint of whalers, begins in Lajes on Pico Island on the last Sunday of August and runs through the week—Whalers Week. It is marked by social and cultural events connected to the tradition of whale hunting. The Wine Harvest Festival (or Festa das Vindimas), takes place during the first week of September and is a century-old custom of the people of Pico.

On Corvo the people celebrate their patron saint Nossa Senhora dos Milagres (Our Lady of Miracles) on 15 August every year in addition to the festivals of the Divine Holy Spirit. The Festival da Maré de Agosto (August Sea Festival), takes place every year beginning on 15 August in Praia Formosa on Santa Maria. Also, the Semana do Mar (Sea Week), dedicated almost exclusively to water sports, takes place in August in the city of Horta, on Faial.

Carnaval is also celebrated in the Azores. Parades and pageants are the heart of the Carnaval festivities. There is lively music, colorful costumes, hand-made masks, and floats. The traditional bullfights in the bullring are ongoing as is the running of bulls in the streets.

History of the Azores

The following article describes the history of the Azores.

Father José António Camões was a Portuguese Catholic priest, poet and historian. He wrote several works of satire, including his heroic satire O Testamento de D. Burro, Pai dos Asnos.

Aviation in the Azores is part of the greater history of aviation in Portugal, and involves the historical use of the archipelago of the Azores by North American, South American and European pioneers of aviation. The Azores is strategically located in the centre of the North Atlantic Ocean between the continents of North America and Europe, and has played a historical role in trans-Atlantic navigation. The three primary airfields of the Azores are:

Azores Day is a regional holiday established to commemorate the Azorean political autonomy established in the Portuguese constitution, following the Carnation Revolution. The date corresponds to the festival of the Holy Spirit, a celebration based in the archipelago's religious and cultural history, held on the Sunday of Pentecosts, a movable public holiday observed only in the archipelago of the Azores.

The Captaincies of the Portuguese Empire were the socio-administrative territorial divisions and hereditary lordships established initially by Henry the Navigator, as part of the Donatário system in order to settle and developed the Portuguese overseas Empire. Pioneered on the island of Madeira and institutionalized in the archipelago of the Azores, the captaincy system was eventually adapted to the New World.

A Captaincy-General of the Azores (1766—1832) was a politico-administrative structure of governance imposed in the Azores on 2 August 1766, with its seat in Angra. It remained the de facto system of governance for 65 years, until it was abolished on 4 June 1832 by D. Peter IV, but by 1828 its de jure status had made it nonoperational, owing to the revolutionary movements that lead to the Liberal Wars. The creation of the Captaincy-General was part of the Pombaline reforms to the Portuguese administration, during the reign of Joseph I, under the initiatives of Sebastião José de Carvalho e Melo, the Marquess of Pombal, then prime minister. A Captaincy-General operated from the Palace of the Captains-General, under the direction of the titular Captain-General, who operated as the Governor of the Azores, with additional jurisdiction on every island of the Azorean archipelago. The Captaincy-General was succeeded by the Province of the Azores, an ephemeral administrative structure that was collapse in the immediate years.
