Liquine-Ofqui Fault


The Liquine-Ofqui Fault is major geological fault that runs a length of roughly 1000 km in a north-south direction and exhibits current seismicity . It is located in the Chilean northern patagonean Andes.

As the name implies it runs from the Liquine hot springs in the north to the Ofqui Isthmus in the south, where the Antarctic Plate meets the Nazca Plate and the South American Plate in Chile Triple Junction. A large parth of the fault runs along the Moraleda Channel. North of Liquine the fault is gradually converted into a compression area. At Quetrupillan volcano the fault is crossed by the Gastre Fault Zone. It may be classified as a dextral intra-arc transform fault.

The 1960 eruption of Cordon Caulle soon after the Great Chilean Earthquake was triggered by movements in the fault. The Aysen Fjord earthquake in 2007 and the eruption of Chaiten Volcano in 2008 are belivied to have been caused by movements in the fault.
