Research activities in this field regard primarily modeling of tsunamis generation by dislocation events, slope failures and volcanic eruptions as well as the study of tsunami propagation and impact on the coasts and on coastal structures and infrastructures. With reference to the tsunami generation by earthquakes, a novel research activity regards the characterization of slip heterogeneities on the fault planes depending on the earthquake magnitude and focal mechanism, as well as on the particular tectonic environment where the earthquakes occurs. Applications are the assessing of tsunami hazard, vulnerability and risk in the European seas with special attention to Italy and the setting up of monitoring network and tsunami alert systems. Most of these activities have been undertaken in the recent past in the frame of European RD projects (TRIDEC, NearToWarn, ASTARTE).
