In the frame of a comprehensive investigation of historical earthquakes of Anatolia, we propose a re-appraisal of four major earthquakes/sequences occurred after 1000 AD (1114/1115, 1269, 1513/1514 and 1544), which could be considered as predecessors of the earthquakes of February 6, 2023. The main purpose is to provide reliable parameter values fo...

The 1693 Noto earthquake, which struck on 11 January, is one of the Italy’s largest and most devastating earthquakes. According to the Italian Parametric Earthquake Catalogue, it reached a maximum intensity of 11 on the Mercalli–Cancani–Sieberg scale and had an estimated magnitude of M 7.3. Nevertheless, its precise location and source definition r...

Introduction. Following the goal of CPS (Centro di Pericolosità Sismica, Center for Seismic Hazard) that is to develop a new Italian seismic hazard map, we propose an updated macroseismic intensity attenuation model for the whole Italian territory and Sicily (without Mount Etna area) that can be applied for computing PSHA in terms of macroseismic i...

Investigating relationships between macroseismic intensity and strong-motion data requires the existence of these two records for the same seismic event and site. In Italy, this comparison is feasible through the cross-matching of the Italian Macroseismic Database (DBMI) and the Italian Strong-Motion Database (ITACA) which are the most comprehensiv...
