The revision of the October 30, 1901 earthquake, west of Lake Garda (northern Italy)

On November 24, 2004 an earthquake (M_w= 5.0) struck the west side of Lake Garda (northern Italy), producing moderate but widespread damage. It provided the opportunity of reviewing the seismicity of all the area over the past two centuries, whose former most significant event is the October 30, 1901 earthquake (M_w= 5.5), while other minor but damaging events are the January 5, 1892 (M_w=5.0) and November 16, 1898 (M_w=4.6) earthquakes. On the reviewing we found common similarities in ground shaking distribution as recurrent damaged spots, amplification zones due to local site condition or energy radiation. We believe that these findings are suitable to provide information for provisional purposes in low hazard level area hampered by the lack of knowledge about the seismic sources. New data are provided both in MCS scale and EMS. The sensitivity of a source parameters estimation technique was evaluated for the major event.
