the mixture of natural and artificial seismic sources with random distributions cause diffuse wave field with random amplitudes and phases called noise. when noise is analyzed in a long-term process, it contains surface waves which are spread in all directions. thus, ambient noise contains data relevant to the surface waves. in recent years, as broadband seismic networks have been distributed v...

Based on Biot’s theory and the indirect boundary element method (IBEM), Monte Carlo is utilized to generate random samples calculate displacement response of a saturated sedimentary valley under SV wave incidence. The purpose this paper explore effects randomness porosity, permeability coefficient, geometric shape seismic amplification effect complex sites. It shown that change media porosity i...

Seismic microzonation is defined as the process of subdividing a potential seismic or earthquake-prone area into zones with respect to some geological and geophysical characteristics sites such ground shaking, liquefaction susceptibility, landslide, rock fall hazard, earthquake-related flooding, etc. Very often, data are used from existing motion that related other geographical regions thus lea...

The Karmania Hazard Model (KHM) is a GIS-based application for earthquake scenario development and disaster management. The lack of integrated and automated tools for estimating resources needed in the aftermath of an earthquake during the disaster response phase motivated the design and implementation of a comprehensive, interactive, and user-friendly model. This model draws on datasets integr...
