The geography of Italy includes the description of all the physical geographical elements of Italy. Italy, whose territory largely coincides with the homonymous geographical region, is located in southern Europe and comprises the long, boot-shaped Italian Peninsula crossed by the Apennines, the southern side of Alps, the large plain of the Po Valley and some islands including Sicily and Sardinia. Italy is part of the Northern Hemisphere. Two of the Pelagie Islands are located on the African continent.
The Tyrrhenian Sea is part of the Mediterranean Sea off the western coast of Italy. It is named for the Tyrrhenian people identified with the Etruscans of Italy.
The French Overseas Department of Martinique is a Caribbean island belonging to the Lesser Antilles group in the Caribbean Sea, southeast of Cuba and north of Trinidad and Tobago. It is part of the French West Indies. It lies near the Tropic of Cancer between 14° 26' and 14°53' latitude north and 63° 9' and 63° 34' longitude west. At most some 50 miles long and 22 miles wide, Martinique covers an area of 425 square miles. Its coastline is so indented that no part of the island is more than seven miles from the sea.
Iceland is an island country at the confluence of the North Atlantic and Arctic oceans, east of Greenland and immediately south of the Arctic Circle, atop the constructive boundary of the northern Mid-Atlantic Ridge about 860 km (530 mi) from Scotland and 4,200 km (2,600 mi) from New York City. One of the world's most sparsely populated countries, Iceland's boundaries are almost the same as the main island – the world's 18th largest in area and possessing almost all of the country's area and population and also it is world's 9th largest island country. It is the westernmost European country and has more land covered by glaciers than in all of continental Europe. The total size is 103,125 km2 (39,817 sq mi). It has an exclusive economic zone of 751,345 km2 (290,096 sq mi).
Ischia is a volcanic island in the Tyrrhenian Sea. It lies at the northern end of the Gulf of Naples, about 30 kilometres from Naples. It is the largest of the Phlegrean Islands. Roughly trapezoidal in shape, it measures approximately 10 km east to west and 7 km north to south and has about 34 km of coastline and a surface area of 46.3 square kilometres (17.9 sq mi). It is almost entirely mountainous; the highest peak is Mount Epomeo, at 788 metres. The island is very densely populated, with 62,000 residents.
The volcanism of Italy is due chiefly to the presence, a short distance to the south, of the boundary between the Eurasian Plate and the African Plate. Italy is a volcanically active country, containing the only active volcanoes in mainland Europe. The lava erupted by Italy's volcanoes is thought to result from the subduction and melting of one plate below another.
Eldfell is a volcanic cone just over 200 metres (660 ft) high on the Icelandic island of Heimaey. It formed in a volcanic eruption, which began without warning on the eastern side of Heimaey, in the Westman Islands, on 23 January 1973. The name means Hill of Fire in Icelandic.
The Phlegraean Fields is a large volcano situated to the west of Naples, Italy. It was declared a regional park in 2003. The area of the caldera consists of 24 craters and volcanic edifices; most of them lie under water. Hydrothermal activity can be observed at Lucrino, Agnano and the town of Pozzuoli. There are also effusive gaseous manifestations in the Solfatara crater, the mythological home of the Roman god of fire, Vulcan. This area is monitored by the Vesuvius Observatory. It is considered a supervolcano.
The Pontine Islands are an archipelago in the Tyrrhenian Sea off the coast of Lazio region, Italy. The islands were collectively named after the largest island in the group, Ponza. The other islands in the archipelago are Palmarola, Zannone, and Gavi to the northwest and Ventotene and Santo Stefano to the southeast. These two groups are separated by 22 nautical miles (41 km). From Sabaudia-Cape Circeo peninsula to Zannone the distance is 12 nautical miles (22 km), while Ventotene faces Gaeta. The minimum distance between Santo Stefano and the isle of Ischia is 22 nautical miles (41 km).
The Danakil Desert is a desert in northeast Ethiopia, southern Eritrea, and northwestern Djibouti. Situated in the Afar Triangle, it stretches across 136,956 square kilometres (52,879 sq mi) of arid terrain. It is inhabited by a few Afar, who engage in salt mining. The area is known for its volcanoes and extreme heat, with daytime temperatures surpassing 50 °C (122 °F). Less than 25 mm (1 in) of rainfall occurs each year. The Danakil Desert is one of the lowest and hottest places on Earth.
La Malinche, also known as Matlalcueye or Malintzin, is an active volcano located in the states of Tlaxcala and Puebla in Mexico. Officially, its summit reaches 4,461 metres (14,636 ft) above sea level, though it is generally considered to be closer to 4,440 metres (14,567 ft), using GPS measurements. It is the highest peak in Tlaxcala, the fifth-highest in Puebla, the sixth-highest in Mexico, the 23rd-highest in North America, and the 252nd-highest in the world. Its height above nearby cities varies from 1,908 metres (6,260 ft) above Huamantla, 2,461 metres (8,074 ft) above Villa Vicente Guerrero, 2,221 metres (7,287 ft) above Tlaxcala, to 2,299 metres (7,543 ft) above Puebla. The summit is 22.4 kilometres (13.9 mi) from Tlaxcala, 28.3 kilometres (17.6 mi) from Puebla, and 118 kilometres (73 mi) from Mexico City. The climate is cold near the summit and mild on the lower slopes.
Citara is a beach located in Forio d'Ischia, in the Ischia island of Italy, near Punta Imperatore and the village of Panza. Its name comes from Romans who consecrated the site to Venus Citarea, whose statue made of white marble was found in the area. An old legend has it that the rocks, which can be seen from the beach, were in origin sailors transformed into stones as a punishment for passing through. The reference is from Odysseus, in which it is told that “Feaci” provided Ulysses with a boat to get home, so the goddess Venus punished them for helping him. On Citara Beach the Poseidon Thermal Garden is provided with a series of sea and thermal water swimming pools. It is known for its sun catching position and limpid sea. Spring water gushes into the sea.
Mount Pico is a currently quiescent stratovolcano located on Pico Island, in the mid-Atlantic archipelago of the Azores. It is the highest mountain in 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. It has been a designated nature reserve since 1972.
The Phlegraean Islands are an archipelago in the Gulf of Naples and the Campania region of southern Italy.
Vivara is a satellite islet of Procida, one of the three main islands in the Gulf of Naples.
The geology of Chile is a characterized by processes linked to subduction such as volcanism, earthquakes and orogeny. The buildings blocks of Chile's geology assembled during the Paleozoic Era. Chile was by then the southwestern margin of the supercontinent Gondwana. In the Jurassic Gondwana began to split and the ongoing period of crustal deformation and mountain building known as the Andean orogeny began. In the Late Cenozoic Chile definitely separated from Antarctica, the Andes experienced a great rise accomplained by a cooling climate and the onset of glaciations.
The Madonie are one of the principal mountain ranges on the island of Sicily, located in the Northern part of the island.
The geography of the Heard Island and McDonald Islands (HIMI) refers to the geography of Heard Island and the McDonald Islands, one of the most remote places on earth. The islands belong to Australia and are located 4,000 kilometres (2,485.5 mi) southwest of the mainland in the Southern Ocean. These subantarctic islands were transferred to Australia by the United Kingdom in 1947. They lie between Madagascar and Antarctica.
The island of La Palma in the Canary Islands is at risk of undergoing a large landslide, which could cause a tsunami in the Atlantic Ocean. Volcanic islands and volcanoes on land frequently undergo large landslides/collapses, which have been documented in Hawaii for example. A recent example is Anak Krakatau, which collapsed to cause the 2018 Sunda Strait tsunami.
The 1883 Casamicciola earthquake, also known as the Ischia earthquake occurred on 28 July at 20:25 local time on the island of Ischia in the Gulf of Naples in Italy. Although the earthquake had an estimated moment magnitude of 4.2 to 5.5, considered moderate in size, it caused intense ground shaking that was assigned XI (Extreme) on the Modified Mercalli intensity scale. Of the 26,000 inhabitants in the town of Casamicciola, at least 2,313–3,100 people lost their lives. The city also suffered great property losses, with 80% of all homes destroyed. This earthquake was exceptionally destructive for its magnitude mainly due to its shallow focal depth.
