The seismogenic sources of the 1976 Friuli earthquakes: a new seismotectonic model for the Friuli area

M.E. Poli and A. Zanferrari

Received: 24 September 2017; accepted: 31 October 2017

Abstract

By matching interpretation of seismic profiles of the Friuli pre-Alpine area with the surficial data collected during the detailed geological survey (CARG - FVG project), we have reconstructed the deep arrangement of the Susans-Tricesimo thrust (which is considered the seismogenic source of the 6 May 1976 earthquake, MW 6.45). The structural framework of the upper crust in Friuli is here updated, suggesting a new seismotectonic model based on the slip partitioning between the Idrija-Ampezzo right lateral strike-slip system and the SSW-verging thrust system of central-eastern Friuli. This new seismotectonic model may have crucial consequences for the assessment of seismic hazard in Friuli.
