Led by Dr. Paolo Bergamo, this group develops various methods to estimate site-specific amplification for local seismic hazard assessments. These methods rely on geophysical measurements and earthquake recordings, combining both empirical and numerical simulations derived from geophysical models. The group produces detailed models of ground motion that inform risk mitigation strategies. Their work is essential for updating national standards, such as those for building codes and dam regulations, and for producing accurate local seismic hazard assessments. Collaborating with ENSI, the group is mandated to update the Swiss stochastic ground motion model and develop new tools to estimate ground motions at depth from surface earthquake recordings, e.g. for the proposed nuclear waste repository.
