Geodetic, geological and geophysical evidence of active tectonics in south-western Sicily and offshore
tIntegrated geological, geodetic and marine geophysical data provide evidence of active deformation insouth-western Sicily, in an area spatially coincident with the macroseismic zone of the destructive 1968Belice earthquake sequence. Even though the sequence represents the strongest seismic event recordedin Western Sicily in historical times, focal solutions provided by different authors are inconclusive onpossible faulting mechanism, which ranges from thrusting to transpression, and the seismogenic sourceis still undefined. Interferometric (DInSAR) observations reveal a differential ground motion on a SW–NEalignment between Campobello di Mazara and Castelvetrano (CCA), located just west of…
Geodetic and geological evidences of activetectonics in western Sicily (Italy): insights onthe seismogenic source of the 1968 Beliceearthquake sequence.
The night between the January 14th and 15th 1968, a wide area of western Sicily (Italy) was shaken by a strong earthquake, the main shock of a seismic crisis that hit the region until the January 25th. The disastrous event, that is the strongest seismic event recorded in Western Sicily in historical times, caused about 370 deaths and the destruction of many villages facing the Belice river valley, which was the epicentral area for this unexpected natural disaster. The seismic sequence consisted of a main shock with M=5.9 and a series of pre-shock and aftershocks that were clustered along a NE-SW alignment. Focal planes solutions provided by many authors in the last decades show controversia…
