The 22 March 2020 Zagreb ML 5.5 earthquake ground shaking resulted in damage to buildings and infrastructure. most affected were older cultural heritage (built before 1963) the old city centre with significant extent epicentral zone (southeastern foothills of Medvednica Mt.). This study presents site response analysis on realistic profiles from epicentre towards accelerometric stations QUHS QAR...

SUMMARY In this paper, we simulate the earthquake that hit city of L’Aquila on 2009 April 6 using SPEED (SPectral Elements in Elastodynamics with Discontinuous Galerkin), an open-source code able to propagation seismic waves complex 3-D domains. Our model includes accurate reconstruction Quaternary deposits, according most up-to-date data obtained from Microzonation studies Central Italy and a ...

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...

Seismic modeling aids the geophysicists to have a better understanding of the subsurface image before the seismic acquisition, processing, and interpretation. In this regard, seismic survey modeling is employed to make a model close to the real structure and to obtain very realistic synthetic seismic data. The objective of this study is to analyze the resolution and illumination of the fault by...

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...
