Mate Grande is a volcanic caldera in Aysén Region, southern Chile.[1] The volcano was discovered by geologists of the University of Chile and the discovery announced in 2021.[2] [1] It lies along the Liquiñe-Ofqui Fault.[1] The volcano received the name Mate Grande in honor of the mate drink that is popular in southern Chile.[1] Mate Grande hosts rocks that cooled from lava less than five thousand years old and is thus considered an active volcano. The diameter of caldera is about 5 km.[1]
