Its highest point is unofficially named Monte Shipton (2,580 m (8,465 ft)), in Chile. Nearby Mount Darwin was previously thought to be the tallest mountain on the island, but is just less than a hundred metres shorter.[2] The northern parts of the island have oil deposits; Cerro Sombrero in Chile is the main extraction centre in the island.
On 17 December 1949, an earthquake occurred in the Chilean portion, near the Argentine border. Recorded as 7.8 on the moment magnitude scale, it was the most powerful ever recorded in the south of Argentina.[3]
Tierra del Fuego is bounded on the east by the South Atlantic, on the north by the Magellan Straits and on the south and west by a series of fjords and channels linked to the Pacific Ocean. One of the few prominent features of the northeast shore is San Sebastián Bay. To the south the island is bounded by the Beagle Channel, south of which lie a series of islands included in Chilean territory. To the west the island has two major inlets, Inútil Bay and Almirantazgo Fjord. The latter lies along the Magallanes–Fagnano Fault and is a continuation of the Cami Lake depression in southern Tierra del Fuego.
The southwest part of the island, between the Almirantazgo Fjord and the Beagle Channel and extending west to end at Brecknock Peninsula on the Pacific Ocean, is mountainous with a heavily indented coastline, dominated by the Cordillera Darwin. Most of this part of the island is included in the Alberto de Agostini National Park of Chile.
The earliest human settlement occurred more than 10,000 years ago, as people migrated from the mainland, perhaps under pressure from competitors. The Yaghan people were some of the earliest known humans settling in Tierra del Fuego. Certain archeological sites at locations such as Navarino Island, within the islands of Tierra del Fuego, have yielded artifacts and evidence of their culture from the Megalithic era.
The name Tierra del Fuego derives from Portuguese explorer Ferdinand Magellan, who was the first European to visit these lands in 1520, on his voyage to the Philippines from Spain. He believed he was seeing the many fires (fuego in Spanish) of the Amerindians, which were visible from the sea and that the "Indians" were waiting in the forests to ambush his armada. These were fires lit by the Yamana Indians who live in the northern part of the island, to ward off the low temperatures in the area. Originally called the "Land of Smoke", it was later changed to the more exciting "Land of Fire".
The British commander Robert Fitzroy, on his first voyage aboard HMS Beagle in 1830, captured four native Fuegians after they stole a boat from his ship. The men included Orundellico, later named Jemmy Button by his crew. Fitzroy taught them English and took them with him on his return to England, where he took them to Court to meet the King and Queen in London. They became early celebrities. The surviving three were returned to Tierra del Fuego on the second voyage of Beagle, which included the naturalist Charles Darwin, who made extensive notes about his visit to the islands.
In July 1881 the island was divided between Argentina and Chile, each of which had previously claimed it entirely.
This was the most powerful earthquake ever recorded in the south of Argentina. It was felt with grade VIII in the Mercalli intensity scale, and affected the settlements and some others like Punta Arenas and Río Gallegos. Due to low population density, damage was limited.[3]
Climate
The region has a subpolar oceanic climate and a mild tundra climate (Köppen climate classificationCfc and ET) with short, cool summers with a mean at around 10 °C (50 °F) and long, cool and wet winters with a mean at around 0 °C (32 °F). The northeast is characterized by strong winds and little precipitation, while in the south and west it is very windy, foggy, and wet most of the year, with precipitation levels averaging 3,000 millimetres (120 in) a year. The permanent snow line begins at 700 metres (2,300 ft). Places in the world with comparable climates are the Aleutian Islands, Iceland, Kuril Islands, Campbell Island, the Kerguelen Islands, the Scottish Highlands, and coastal areas of Norway.
In August 1995 the island was hit by an event of intense winds, cold and snowfall known as the White Earthquake. This caused the ferry service across Primera Angostura to be suspended, as well as the international road to Río Gallegos to be closed.[4] In Timaukel alone the mayor reported that 150 thousand sheep and 6,500 heads of cattle were threatened by the event.[5]
The forests of Tierra del Fuego have been a source of trees that have been planted abroad in places with a similar climate but that were devoid of trees, such as the Faroe Islands and nearby archipelagos. Most species were gathered from the coldest places in Tierra del Fuego bordering the tundra. This resulted in positive changes, as the heavy winds and cool summers in the Faroe Islands had not formerly allowed the growth of trees from other regions in the world. In the Faroe Islands, the imported trees are used ornamentally, as curtains against wind, and for fighting erosion caused by storms and grazing.

The main industries are oil, natural gas, sheep farming and ecotourism. On the Argentine side several electronics companies have been established. Ushuaia is home to the small brewing company Cervecería Fueguina, which produces three beers under the Beagle brand name.
