Abstract

A wide survey of the construction damages held in the nearby historic centres of San Pio delle Camere and Castelnuovo (AQ), after the 6 April 2009 earthquake in Abruzzo, have been done. The soil of the upper part of San Pio delle Camere is characterised by high level of consistency, while the soil of the lower part of the village and of the Castelnuovo burg is generally highly compressible, performing relevant amplifications during the earthquake. Moreover the usual typology of constructions, made up by irregular stones masonry with poor mortar, assures a relative uniformity of the response to the earthquake. From the numerous damage mechanisms on the facades and on the internal parts of the buildings, a map of the equivalent PGA experimented during the above seism has been determined. In addition, the study of the signals recorded by some accelerometric stations around the epicentre, and processed with proper attenuation laws, furnishes further data for the seismic microzonation of the area.
