Mocha-Villarrica Fault Zone

Aerial view of the volcanic alignment of Villarrica (closest), Quetrupillán and Lanín (farthest).

The Mocha-Villarrica Fault Zone is a northwest-trending geological fault zone in southern Chile and Argentina.[1] The fault zone runs from Mocha Island in the Pacific to the Andes where it aligns Villarrica, Quetrupillán and Lanín volcanoes.[1] It is one of several fault zones that traverses the north-south Liquiñe-Ofqui Fault.[2]
