Investigation of the Factors Controlling the Duration and Productivity of Aftershocks Following Strong Earthquakes in Greece

Strong crustal earthquakes in Greece are typically followed by aftershocks, the properties of which important factors seismic hazard assessment. In order to examine earthquake sequences, we prepared an catalog comprising aftershock sequences with mainshocks Mw ≥ 5.5 from 1995 2021. Regional parameters were estimated highlight variations decay and productivity among regions similar seismotectonic characteristics. A statistically based method estimating duration a metric relative different cases employed. From detailed analysis selected attempt unravel physical mechanisms behind deviations resolve contribution background seismicity, Omori–Utsu law mainshock faulting properties. our analysis, depends upon rupture process mainshock, independently its magnitude. The same applies productivity, however, other tectonic setting (e.g., coupling) or source-related focal depth, stress drop) also contribute. regional rate models could be utilized as initial ones forecast occurrence rates at early stage following mainshock.
