Earthquakes cascade and Earthquake Hazard in the Italian Apennines: Ten Years After L’Aquila.

Session ID#: 80108

Session Description:
Multiple M6+ earthquakes have shaken the Apennine Mountains of central Italy over recent decades (Colfiorito 1997, L’Aquila 2009, Amatrice-Visso-Norcia 2016), making it among the most active areas of Europe with very high vulnerability leading to tragic losses. Advances in seismology, terrestrial-space geodesy and geology make this a natural laboratory for investigating extensional tectonics. Many questions about multiple and close occurrence of shallow normal faulting earthquakes and the hazard they pose remain unanswered. How and were do they nucleate and propagate across complex fault networks?  What are the roles of crustal fluids in the triggering of seismicity?

This session invites contributions from all relevant fields (seismology, geodesy, hydrology, tectonics and laboratory), addressing questions of earthquake mechanics (nucleation, propagation), fluid diffusion, interactions and forecasting. The aim is to critically examine the current understanding to identify future research directions needed to better assess the seismic hazard of this and in similar extensional settings.
