Monitoraggio della sismicità locale nel Cilento nel periodo febbraio-ottobre 2014
Main Article Content
Abstract
Some temporary seismic stations were installed in Cilento from February to October 2014 for a monitoring of the local seismicity in the area of Roccadaspide and surrounding villages, where two earthquakes of magnitude Mw=3.6 and Mw=3.7 occurred on January 22, 2014. Following the warnings of rumbles and tremors from people living in the area, reported also by local press and television, a field survey was realized and the seismic monitoring begun. Acquired data showed a sequence of microearthquakes likely triggered by the two events occurred on January 22. We identified more than 750 very small earthquakes (M<2), of which more than 60 have been located. The 95% of the sources is located in an area of about 10 km2 with depth lower than 3 km. For about 15 earthquakes recorded by at least 5 stations we were able to compute also the focal mechanism. Results of our analysis suggest a predominant distensive dynamics in the epicentral area, although the full picture is rather complex, with significantly different mechanisms for sources very near to each other.
