Special Issue: New Challenges in Seismic Hazard Assessment

With the continuous development of society, the rapid urbanization of cities, and the increasing construction of large-scale infrastructure projects, seismic hazard studies are becoming increasingly necessary. Seismic hazard assessment faces challenges requiring advanced and comprehensive approaches to understand and mitigate potential risks. There are many studies on seismic hazard using different methodological approaches in Italy and worldwide. These include geological records, such as paleoearthquakes, paleotsunamis, and coseismic rupture models [1–8], macroseismic investigations for analyzing the damage evolution during seismic sequences [9–13], and geophysical studies, including seismic and electrical tomography, as well as gravity and magnetic imaging techniques [14–17]. This Special Issue focuses on recent advances in the study of seismic hazards from multiple perspectives. A key aspect of this issue is the contribution of new geological coseismic data and macroseismic analyses evaluated by the ESI scale [18]. These studies are particularly valuable for improving our understanding of the mechanisms of shallow fault- ing caused by small-to-medium earthquakes, even in volcano–tectonic settings. Currently, earthquake data in the magnitude range 3.0 < M < 5.0 are significantly lacking, making this research crucial to fill the current knowledge gap and improve the completeness of available seismic databases.
