An extensive geological, geotechnical and geophysical investigation was undertaken for the seismic microzonation of Avezzano, the main town of Fucino plain (L’Aquila province, Italy). Here, during the 1915 Fucino earthquake evidences of liquefaction were detected. The present study focuses on the liquefaction hazard assessment based on in-situ tests like piezocone (CPTu), dynamic penetration (standard SPT and super heavy DPSH tests), and seismic dilatomer SDMT tests. Results at the test site of Pozzone area have been reported and discussed hereafter. Preliminary results of liquefaction analyses carried out using simplified methods are illustrated, compared and discussed throughout the paper. According to these first outcomes, the SDMT and CPTu investigation methods show similar values of liquefaction susceptibility.

Abstract
An extensive geological, geotechnical and geophysical investigation was undertaken for the seismic microzonation of Avezzano, the main town of Fucino plain (L’Aquila province, Italy). Here, during the 1915 Fucino earthquake evidences of liquefaction were detected. The present study focuses on the liquefaction hazard assessment based on in-situ tests like piezocone (CPTu), dynamic penetration (standard SPT and super heavy DPSH tests), and seismic dilatomer SDMT tests. Results at the test site of Pozzone area have been reported and discussed hereafter. Preliminary results of liquefaction analyses carried out using simplified methods are illustrated, compared and discussed throughout the paper. According to these first outcomes, the SDMT and CPTu investigation methods show similar values of liquefaction susceptibility.Pubblicazioni consigliate
