The present project proposes an innovative, integrated, multidisciplinary study aimed at defining an innovative time-dependent seismic hazard assessment protocol, fundamental for the implementation of advanced and integrated strategy on seismic risk reduction and disaster management. This can lead to define structural design rules to ensure target safety levels considering time-dependent hazard models for short- and long-term time scales. The multidisciplinary approach includes three work packages (WPs): the first two WPs focus on defining the 3D geological/geophysical models and a new time-dependent seismic hazard assessment, whereas the third WP aims at the seismic risk evaluation.
The main results will be used to develop new advanced time-dependent seismic risk protocols and hence to propose new structural design rules for time-dependent seismic hazard through sensitivity analysis and comparison of the most important parameters controlling both time dependent and time independent hazard models.
The selected area for this study is located in the northern portion of Marche Region (Italy), along the Central Apennines, characterized by an intense historical seismicity which includes the Fabriano 1741 (Mw =6.2), Cagli 1781 (Mw 6.4) and Camerino 1799 (Mw =6.2) earthquakes, and most recently the recent seismic sequence started in 2016 (Amatrice, Visso, Norcia earthquakes, Mw max =6.5).
