The 1737 Valdivia earthquake struck south-central Chile on December 24 with an estimated moment magnitude of 7.5. [2] [3] Together with earthquakes in 1575 and 1837 the earthquake is among the historical predecessors to the great 1960 earthquake. [2] While the overlap in affected areas is significant relative to the 1837 earthquake, the 1737 earthquake may have occurred slightly more to the north. [2]
The earthquake was felt in Concepción but most damage occurred in the towns of Valdivia and Castro, Chiloé Archipelago. [2] In both of these locations churches were destroyed by the earthquake. In addition the Valdivian Fort System and the Royal Storehouse of Valdivia took heavy damage. [2] Landslides occurred next to Villarrica, Calafquén, and Riñihue lakes. [2] Over all this indicates the rupture zone was about 640 km long, with most damage being concentrated in the middle section (Valdivia). [2]
There is no evidence the earthquake would have produced a tsunami. [2]
Pedro Gutiérrez de Valdivia or Valdiva was a Spanish conquistador and the first royal governor of Chile. After serving with the Spanish army in Italy and Flanders, he was sent to South America in 1534, where he served as lieutenant under Francisco Pizarro in Peru, acting as his second in command.
Concepción is a city and commune in south-central Chile, and the geographical and demographic core of the Greater Concepción metropolitan area, one of the three major conurbations in the country. It has a significant impact on domestic trade being part of the most heavily industrialized region in the country. It is the seat of the Concepción Province and the capital of the Bío Bío Region. It sits about 500 km south of the nation's capital, Santiago.
The 1960 Valdivia earthquake and tsunami or the Great Chilean earthquake on 22 May 1960 was the most powerful earthquake ever recorded. Most studies have placed it at 9.4–9.6 on the moment magnitude scale, while some studies have placed the magnitude lower than 9.4. It occurred in the afternoon, and lasted 10 minutes. The resulting tsunamis affected southern Chile, Hawaii, Japan, the Philippines, eastern New Zealand, southeast Australia, and the Aleutian Islands.
The Arauco War was a long-running conflict between colonial Spaniards and the Mapuche people, mostly fought in the Araucanía region of Chile. The conflict began at first as a reaction to the Spanish conquerors attempting to establish cities and force Mapuches into servitude. It subsequently evolved over time into phases comprising drawn-out sieges, slave-hunting expeditions, pillaging raids, punitive expeditions, and renewed Spanish attempts to secure lost territories. Abduction of women and war rape was common on both sides.
The Battle of Tucapel is the name given to a battle fought between Spanish conquistador forces led by Pedro de Valdivia and Mapuche (Araucanian) Indians under Lautaro that took place at Tucapel, Chile on December 25, 1553. The battle occurred in the context of the first stage of the Arauco War, named the "offensive war" within a larger uprising by Araucanians against the Spanish conquest of Chile. It was a defeat for the Spaniards, resulting in the capture and eventual death of Valdivia.
Valdivia is a city and commune in southern Chile, administered by the Municipality of Valdivia. The city is named after its founder, Pedro de Valdivia, and is located at the confluence of the Calle-Calle, Valdivia, and Cau-Cau Rivers, approximately 15 km (9 mi) east of the coastal towns of Corral and Niebla. Since October 2007, Valdivia has been the capital of Los Ríos Region and is also the capital of Valdivia Province. The national census of 2017 recorded the commune of Valdivia as having 166,080 inhabitants (Valdivianos), of whom 150,048 were living in the city. The main economic activities of Valdivia include tourism, wood pulp manufacturing, forestry, metallurgy, and beer production. The city is also the home of the Austral University of Chile, founded in 1954 and the Centro de Estudios Científicos.
The Destruction of the Seven Cities is a term used in Chilean historiography to refer to the destruction or abandonment of seven major Spanish outposts in southern Chile around 1600, caused by the Mapuche and Huilliche uprising of 1598. The Destruction of the Seven Cities, in traditional historiography, marks the end of the Conquest period and the beginning of the proper colonial period.
The Conquest of Chile is a period in Chilean historiography that starts with the arrival of Pedro de Valdivia to Chile in 1541 and ends with the death of Martín García Óñez de Loyola in the Battle of Curalaba in 1598, and the destruction of the Seven Cities in 1598–1604 in the Araucanía region.
Francisco Vidal Gormaz was a Chilean naval officer and hydrographer who explored the coasts of Chile including some river systems and lakes. During the 1850s he explored and surveyed several times Maullín River with Francisco Hudson. Before being lost at sea in 1859 Hudson is thought to have been a major influence on Vidal Gormaz. He participated in the Occupation of the Araucanía performing reconnaissance missions in the coasts of Arauco and Toltén. In 1863, he was named director of the Maritime School of Ancud. In 1874, he became the first director of the newly created Hydrographic Office. In 1884, he became General Inspector of Lighthouses and participated in the International Meridian Conference. Because of his neutrality during the 1891 Chilean Civil War he was removed from his post as director of the Hydrographic Office. He was named assistant at the Sea Ministry in 1894 and retired from the navy in 1899.
The 1995 Antofagasta earthquake occurred on July 30 at 05:11 UTC with a moment magnitude of 8.0 and a maximum Mercalli intensity of VII. The Antofagasta Region in Chile was affected by a moderate tsunami, with three people killed, 58 or 59 injured, and around 600 homeless. Total damage from the earthquake and tsunami amounted to $1.791 million.
The 2010 Chile earthquake occurred off the coast of central Chile on Saturday, 27 February at 03:34:12 local time, having a magnitude of 8.8 on the moment magnitude scale, with intense shaking lasting for about three minutes. It was felt strongly in six Chilean regions that together make up about 80 percent of the country's population. According to the United States Geological Survey (USGS) the cities experiencing the strongest shaking—VIII (Severe) on the Mercalli intensity scale (MM)—were Concepción, Arauco, and Coronel. According to Chile's Seismological Service, Concepción experienced the strongest shaking at MM IX (Violent). The earthquake was felt in the capital Santiago at MM VII or MM VIII. Tremors were felt in many Argentine cities, including Buenos Aires, Córdoba, Mendoza, and La Rioja. Tremors were felt as far north as the city of Ica in southern Peru. It is the largest earthquake to hit Chile since the 1960 Valdivia earthquake.
The 1835 Concepción earthquake occurred near the neighboring cities of Concepción and Talcahuano in Chile on 20 February at 11:30 local time and has an estimated magnitude of about 8.5 Mw. The earthquake triggered a tsunami which caused the destruction of Talcahuano. A total of at least 50 people died from the effects of the earthquake and the tsunami. The earthquake caused damage from San Fernando in the north to Osorno in the south. It was felt over a still wider area from Copiapó in the north to the island of Chiloe in the south and as far west as the Juan Fernández Islands.
The 1960 Concepción earthquakes were a succession of three destructive earthquakes that happened between 21 and 22 May 1960. They formed part of the foreshock sequence for the 1960 Valdivia earthquake, the largest recorded earthquake in history.
The 1615 Arica earthquake was a major earthquake centered near Arica in the Spanish colonial Viceroyalty of Peru, within the present day Arica y Parinacota Region of northwestern Chile.
As an archaeological culture, the Mapuche people of southern Chile and Argentina have a long history which dates back to 600–500 BC. The Mapuche society underwent great transformations after Spanish contact in the mid–16th century. These changes included the adoption of Old World crops and animals and the onset of a rich Spanish–Mapuche trade in La Frontera and Valdivia. Despite these contacts Mapuche were never completely subjugated by the Spanish Empire. Between the 18th and 19th century Mapuche culture and people spread eastwards into the Pampas and the Patagonian plains. This vast new territory allowed Mapuche groups to control a substantial part of the salt and cattle trade in the Southern Cone.
The 1837 Valdivia earthquake struck south-central Chile on November 7. Together with earthquakes in 1575 and 1737 the earthquake is among the historical predecessors to the great 1960 earthquake. The rupture zone was roughly from Valdivia to the south. It was felt in the cities of Concepción, Valdivia and Ancud. The earthquake was also felt by the crew whaling ships in Guafo Island and Chonos Archipelago. Various landslides were triggered in Chiloé and people are reported to have been thrown to the ground in Valdivia. In contrast in Concepción the shakings were moderate. As reported in various coastal localities the ground rose as result of the earthquake. Decades later while surveying southern Chile's coasts Francisco Vidal Gormaz was told of islands that been submerged and some that had emerged as a consequence of the earthquake. The earthquake caused a tsunami that struck Hawaii, what is now French Polynesia, and Japan. At Hilo, Hawaii, the tsunami destroyed 66 houses and caused the deaths of 14 inhabitants.
The 1604 Arica earthquake is an earthquake that occurred at 1:30 pm on November 24, 1604, offshore Arica, Chile. The estimated magnitude range is Ms8.0–8.5 and up to Mw8.7–9.0 and Mt8.8–9.0. It had a destructive tsunami that destroyed moust of Southern Peru, including Arica and Arequipa. 1,200–2,800 km (750–1,740 mi) of coastline was affected by the tsunami. The recorded effects of this earthquake are very similar to those for the 1868 Arica event, suggesting a similar magnitude and rupture area of the megathrust between the subducting Nazca plate and the overriding South American plate. Tsunami deposits have been identified on the Chatham Islands that are likely to have been caused by a trans-Pacific tsunami caused by the 1604 earthquake.
The 1822 Valparaíso earthquake was a major earthquake that occurred in Valparaíso, Chile on November 19, 1822. The earthquake has an estimated surface wave magnitude of 8.5. It triggered a moderate tsunami measuring up to 12 ft (3.7 m) along the Chilean coast. The earthquake and tsunami killed between 72 and 300 people and left a further 200 injured.
The 1657 Concepción earthquake occurred on March 15 at 20:00 local time off the coast of Concepción, Biobío Region in the Spanish Empire. The earthquake caused severe damage along the coast, and generated a large tsunami in the Bay of Concepción. At least 40 people were killed, the majority due to drowning from the tsunami. The town of Concepción was the hardest hit, with the earthquake and tsunami totally destroying it.
