Rilievo macrosismico del terremoto del Garda del 24 novembre 2004

Abstract

On November 24, 2004, Northern Italy was struck by a Ml=5.2 earthquake located near the Garda Lake. A few smaller events followed the main shock. The felt area was very large, ranging from Venice to Milan, and from Ljubljana (Slovenia) to Pisa. Significant damage occurred in the epicentral area, which is approximately the same of the October 30, 1901 earthquake. The day after the quake, reconnaissance teams performed a macroseismic survey of the affected area in order to define the damage scenario. Damage was mostly concentrated in the area west of Lake Garda, between the town of Salò and the Valsabbia valley. Damage to old masonry buildings consisted in partial collapses, falling of chimneys and roof tiles and large cracks in walls. Some churches and towers were also damaged. There was almost no damage to reinforced concrete (RC) structures.
