Abstract Background Microzonation becomes important for big cities like Medan (North Sumatra, Indonesia) as population agglomeration increases in urban areas resulting rapid and unplanned construction. Mitigation efforts must be carried out to minimize losses arising from earthquakes, such loss of life environmental damage, it can done by analyzing seismic susceptibility local site effects. Pur...

A novel probabilistic methodology for regional seismic site characterization is proposed and applied to a region with highly heterogeneous surficial geology varying soil sediment thickness stiffness. The method combines various sources of geological geotechnical uncertainties develop three-dimensional (3D) shear-wave velocity ( V s ) model evaluate the associated uncertainties. 3D unconsolidate...

Abstract. Past seismic events worldwide demonstrated that damage and death toll depend on both the strong ground motion (i.e., source effects) local site effects. The variability of earthquake distribution is caused by stratigraphic and/or topographic setting buried morphologies (e.g., irregular sub-interface between soft stiff soils) can give rise to amplification resonances with respect expec...

In the municipality of Enna, 80 HVSR measurements were performed, and some these combined with MASW seismic measurements, which made it possible to constrain data inversion obtain significant shear wave velocity models. A reconstruction depth bedrock was performed for whole territory, showing different depths higher lower areas, as evidenced also by Vseq parameter map. The frequency peaks ident...
