Tsunamis From Submarine Collapses Along the Eastern Slope of the Gela Basin (Strait of Sicily)

摘要: Geophysical surveys in the eastern slope of Gela Basin (Strait Sicily, central Mediterranean) contributed to identification several episodes sediment mass transport, recorded by scars and deposits various dimensions within Pleistocene succession. In addition a megaslide called Slide (GS), with volume exceeding 600 km3, most studied events show volumes estimated between 0.5 1.5 which is common many other submarine landslide this region that can therefore be considered as characteristic value. work, tsunamigenic potential two such landslides, so-called Northern Twin (NTS) South (SGBS), located about 50 km apart along Basin, has been investigated using numerical codes describe onset motion slide, well ensuing tsunami generation propagation. The results provide wave height these on coast southern Sicily Malta taken representative typical landslides occurring Basin.
