Bollettino Sismico Italiano 2013

Abstract

This paper describes the status of the National Seismic Network (RSN) and outlines the main characteristics of the seismicity recorded in Italy during 2013. In this year 417 seismic stations were acquired for the RSN, most of them owned by the National Institute of Geophysics and Volcanology (INGV) while the other coming from local, regional or foreign monitoring networks. The Italian Seismic Bulletin (BSI) of 2013 contains 25180 located earthquakes, of which almost two thirds belong to the 41 seismic sequences identified; among these the most significant is the one that began in June in Lunigiana, which also recorded the strongest earthquake of 2013: ML 5.2, which occurred on June 21st. The minimum magnitude of completeness of the BSI in 2013 is MC 1.2. A chapter of the work illustrates the seismicity of anthropic origin present in the BSI (about 1%) and the seismograms of a collapse landslide occurred in the Alpine arc, an area where phenomena of this type occur very frequently.
