Mass movement-induced tsunamis: main effects during the Patagonian Fjordland seismic crisis in Aisén (45°25'S), Chile

The epicentre of the long-lasting seismic crisis started on the evening of January 22,2007 and it was located 20 km to the west of Puerto Chacabuco in the Patagonian fjordland, Chile (45°25'S). Approximately 7,000 events were recorded up to early May, four of which reached magnitudes greater th...
