However, thesouthern part exhibitsstrongseismicand tsunamogenicpotentialwiththeprominentexampleoftheM =9.5 May22,w1960 Valdivia earthquake. In this study data from an amphibious seismic array (ProjectTIPTEQ) is presented. The network reached from the trench to the active magmaticarc incorporating the Island of Chiloé and the north-south trending Liquiñe-Ofqui faultzone (LOFZ). 364 local events were observed in an 11-month period from November2004 until October 2005.
