Geologic Background:
The Carran-Los Venados volcano group includes a
group of 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 Cordon
Caulle-Pueyhue
volcanic chain. The Mirador scoria cone and two maars,
Rininahue and Carran, were formed during the 20th
century. They are concentrated where the regional
Liquine-Ofqui fault zone intersects the alignment of
volcanic vents.
Historic Activity:
- Three historic eruptions from three different
vents.
