Carran-Los Venados

Cono piroclastico · Chile · 1114 m

An ash plume rises from Volcan Mirador, a pyroclastic cone that formed during an eruption in 1979.  The Carran-Los Venados volcano group includes about 50 scoria cones, maars, and a small stratovolcano that are broadly aligned along a 17-km-long ENE-WSW trend.  The volcano group occupies a low-lying area north of the Cordón Caulle-Pueyhue volcanic chain.  In addition to the 1979 Mirador scoria cone, two maars, Rininahue and Carran, were formed during eruptions in the 20th century.

Sintesi geologica

The Carrán-Los Venados volcano group includes about 50 basaltic to basaltic andesite scoria cones, maars, and a small stratovolcano that are broadly aligned along a 17-km-long ENE-WSW trend ESE of Lago Ranco. The volcanic features occupy a low-lying area N of the more topographically prominent Puyehue-Cordón Caulle volcanic chain, and many of the vents are postglacial in age. The Mirador scoria cone and two maars, Riñinahue and Carrán, were formed during eruptions in the 20th century. These historical eruptions were concentrated where the regional Liquine-Ofqui fault zone intersects the alignment of volcanic vents.

Riassunto in inglese

Carrán-Los Venados is a volcanic group of scoria cones, maars and small stratovolcanoes in southern Chile, southeast of Ranco Lake. The highest cone is Los Guindos, which is a small stratovolcano with an elevation of 1,114 metres (3,655 ft). The volcanic group has recorded eruptions from 1955 and 1979. Located south of Maihue Lake and north Puyehue Volcano Carrán-Los Venados group is placed at the intersection of several faults on the thin crust (~30 km) of southern Chile, among them Liquiñe-Ofqui and Futrono Fault.
