Abstract

A research approach that integrated different geophysical methods for local subsoil evaluation using for seismic microzonation studies was carried out in this research paper. The gravity prospecting were made to map and model the thickness of Quaternary deposits (gravel, sand and clay) overlaying the Meso-Cenozoic pelagic basin deposits of the Leonessa basin. The Leonessa basin is one of the major intermontane tectonic depressions of Central Apennines boarded on the southern side by the great normal fault, here referred to as the Leonessa fault. The study involved a test area of 32 km2 occupied by 250 gravity stations. The stations were accurately located with differential GPS (Ashtech Z-Xtreme dual-frequency GPS) that provided centimetric accuracy in elevation. The gravity measurements were performed using a LaCoste & Romberg gravimeter mod. D60 that has a reading resolution and an accuracy of 0.01 mGal. Measurements have been done in the depressions and also over the basement in ord
