2007 earthquakes

A series of earthquakes occurred below the Aisén Fjord 20 km south of the volcano, with 7000 earthquakes recorded between 22 January and early May 2007. The largest earthquake was magnitude 6.2 on 23 April 2007 along the major Liquiñe-Ofqui Fault. It has been suggested that the earthquake swarm was triggered the eruption of Chaiten volcano 250 km further north in May 2008, in a similar way as it might have triggered the 1960 eruption of Cordón Caulle soon after the Great Chilean Earthquake on 22 May 1960.
