Abstract Recent studies found that some structural damage can be attributed to the effect of surface waves. A shallow underground structure may heavily influenced by waves, which makes lose energy over distance more slowly than body This study deals with evaluating Rayleigh waves (R-waves) interaction cavities on seismic ground response and amplification pattern using Finite Element Method (FEM...

We analyzed 12 years of continuous seismic data acquired by two stations in Central Apennines (Italy) with the aim to investigate temporal variations H/V spectral ratios. The are located epicentral areas main strong motion earthquakes occurred Italy last (L’Aquila 06 April 2009, Mw 6.1; Amatrice 24 August 2016, 6.0; Visso 26 October 5.9, and Norcia 30 6.5). ratios computed both on recorded stat...

Abstract The latest studies concerning seismic risk assessment in Italy were developed without considering the site geo-lithological effects, thus limiting to rock soil type. In this study, for evaluation of amplification we used results recent works based on Italian microzonation data. As first study is performed entire territory at municipality scale, factors (AFs) have been assigned chief to...
