AB: In past years, earthquake forecasting and seismic hazard in Italy have been approached by using geological and geophysical data yielding only a partial definition of seismic release for the main active structures. In this project, we collect seismological and geodetic data to yield deterministic constraints for seismic hazard studies in areas where large earthquakes are expected to occur in a near future, called lacunae. The basic idea is to massively deploy arrays of instruments in the lacunae areas to acquire seismic and geodetic data with the goals of defining location, geometry and kinematics of the active faults and possibly constraining their strain rate. We selected three target regions: two along the Apennines (Northern Umbria and Abruzzo) and one in the Southern Alps (Alpago-Cansiglio). These areas are characterized by different tectonics and different historical seismic release. We present results for the areas located along the Apennines: the Umbria 2000-2001 and the Abruzzo 2003-2004 experiments while for the Alpago-Cansiglio we are still collecting and processing data. Preliminary results for the Umbria lacuna shows that the collected microearthquakes allow us to clearly recognize the fault system geometry and the deep structure (P- and S-wave velocity and attenuation).
