Foreland seismicity associated with strike-slip faulting in southeastern Sicily, Italy: Seismotectonic implications and seismic hazard assessment

摘要

Between February 6 and 12, 2016, an earthquake sequence affected the western sector of the Hyblean foreland domain in SE Sicily (Italy), a region characterized by several disastrous events, as the seismic history describes, of which little is still known about the seismogenic sources. Despite the low magnitude of most events (M-Lmax 4.3), the sequence represents one of the largest episodes of seismic strain release in the area over the last 30 years since the December 13, 1990 earthquake (M-L = 5.4).
