Description:
Eastern Sicily is an area where some of the most catastrophic earthquakes in Italian history occurred.
As reported by historical sources, these earthquakes induced liquefaction phenomena. In two areas
along the Ionian coast of Sicily we found liquefaction evidence in Holocene deposits. In the Minissale
site (east of Mount Etna), the observed liquefaction features can be related to the 1169 and 1693
earthquakes, while in the Agnone site (south of Catania), the deformational structures can be
tentatively associated to the 1542 and 1693 events. Both sites locate in areas where historical
liquefaction has been observed in the past, thus confirming the actual liquefaction susceptibility/
potential in this region. The evidence of repeated liquefaction events at the same site, highlights the
relevance of the paleoseismic approach for modeling the recurrence time and preparing scenarios of
seismic effects in eastern Sicily, where seismogenic sources are scantly defined.
