Isla Grande de Tierra del Fuego (
The island has an area of 47,992 km2 (18,530 sq mi), making it the largest island in South America and the 29th largest island in the world. Its two biggest towns are Ushuaia and Río Grande, both in Argentina. Other towns are Tolhuin, Porvenir, Camerón, and Cerro Sombrero. The Argentine side, Tierra del Fuego Province, has 127,205 inhabitants (2010), whereas the Chilean side, even though its area is significantly larger, has only 6,656 (2012), almost all located in the Tierra del Fuego Province.
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]
Geography
Tierra del Fuego is bounded on the east by the
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.
History
The earliest human settlement occurred more than 10,000 years ago, as people migrated from the mainland, perhaps under pressure from competitors. The
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".

In July 1881 the island was divided between Argentina and Chile, each of which had previously claimed it entirely.

Flora
Only 30% of the islands have forests, which are classified as
There are six species of tree found in Tierra del Fuego: Canelo or Winter's Bark (
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.
Economy
This section needs expansion. You can help by adding to it. (April 2022) |
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.

When these 2 sources are used together, the record highs and lows are from the period 1901–present.
