The Lunigiana and Garfagnana areas are located in the northwestern termination of the Etrurian Fault System which is a NW-SE trending normal fault system with a length of about 350 km from Umbria to Tuscany [1]. Historical observations and studies of seismicity showed it is an active and seismogenic zone. In this work we investigate and model the Mw 5.3 (Ml 5.2), June 21st, 2013 earthquake, occurred in the discontinuity zone between the Lunigiana and Garfagnana areas. Our results suggest that the fault responsible for the June 2013 earthquake may correspond to a breached relay ramp connecting the Lunigiana and Garfagnana seismogenic sources

Abstract

The Lunigiana and Garfagnana areas are located in the northwestern termination of the Etrurian Fault System which is a NW-SE trending normal fault system with a length of about 350 km from Umbria to Tuscany [1]. Historical observations and studies of seismicity showed it is an active and seismogenic zone. In this work we investigate and model the Mw 5.3 (Ml 5.2), June 21st, 2013 earthquake, occurred in the discontinuity zone between the Lunigiana and Garfagnana areas. Our results suggest that the fault responsible for the June 2013 earthquake may correspond to a breached relay ramp connecting the Lunigiana and Garfagnana seismogenic sources
