Yanteles is an isolated stratovolcano composed of five glacier-capped peaks along an 8 km-long NE-trending ridge. It is located approximately 30 km (19 mi) south of the Corcovado volcano in the Chilean X Region ( de Los Lagos) within the Corcovado National Park. The name Yanteles can refer only to the main summit, which is also known as Volcán Nevado ( Spanish for "Snow-covered Volcano").
The volcano lies in the Chaitén municipality, Palena region, Los Lagos Region of Chile. Villa Santa Lucía and Bahía Tic-Toc are the closest settlements to the volcano, [3] while Chaitén is 60 kilometres (37 mi) away. [4] The elongated edifice is 2,042 metres (6,699 ft), [5] 1,790 metres (5,870 ft) [4] or 1,971 metres (6,467 ft) high and covers an area of 84.5 square kilometres (32.6 sq mi), making it a large volcano. Three stratovolcanoes developed on a north-south trending fault [3] and five peaks form a ridge trending northeastward. [5] Volcanoes like Yanteles form the highest summits of the Andes at these latitudes. [6] It also features a caldera with a pyroclastic cone. [7] Eroded peaks occur in the vicinity [2] and Nevado and Yeli are volcanic necks associated with the system. [7] Another major fault in the region is the Melimoyu-Yanteles Fault. [8]
It is covered by sizeable glaciers, [3] which with an area of 46.24 square kilometres (17.85 sq mi) (As of 2007 [update]) form one of the largest areas of ice in the region. It has been declining at a rate of 0.72 square kilometres per year (0.28 sq mi/a). [9]
Yanteles has erupted basaltic andesite. [3] The volcano is geologically part of the Southern Volcanic Zone of the Andes. [10]
The volcano was active in the Pleistocene- Holocene and the last major eruption was 6,650 BCE. [3] The volcano is considered to be a source of tephra layers [4] such as the 7,240±150 BCE eruption that produced the YAN1 tephra. [11]Another eruption took place 10,340±180 years before present. [12] One tephra in the Siple Dome of Antarctica [13] and tephras found in Patagonian lakes may come from Yanteles. [10]
Yanteles is little known, [4] but attested in a 1899 publication [14] and was known to be a volcano as far back as 1916. [15] The occurrence of historical eruptions is uncertain; [5] Yanteles reportedly [16] erupted a day after the 1835 Concepcion earthquake and activity continued for months, [17] but little is known about this activity [4] and its description as patches of bare rock or the disappearance of snow makes the record doubtful; [18] such a change could constitute landsliding instead. [19] Later activity is limited to fumarolic activity in 1982, 1992 and 1993-1995. [3] Two fumarolic areas were reported in 1993 on the ridge, 2 kilometres (1.2 mi) from each other, and were emitting yellow-to-white steam. [20]
Future eruptions could cause mudflows in the valleys around the volcano. [3] It was classified as a type III volcano by SERNAGEOMIN, implying an intermediate volcanic hazard. [21]
