The present study was conducted to determine peak ground acceleration (PGA) over bedrock in probabilistic analysis methods for the seismic hazard and uniform hazard spectra at different hazard levels for Esfahan city. A series of statistics containing historical and instrumental seismic data covering from the 8th century A.D. to the now up to a radius of 200 km was employed and seismic sources ...

A natural hazard is a geophysical, atmospheric or hydrological event (e.g., earthquake, landslide, tsunami, windstorm, flood or drought) that has the potential to cause harm or loss, while a natural disaster is the occurrence of an extreme hazardous event that impacts on communities causing damage, disruption and casualties, and leaving the affected communities unable to function normally witho...

Peak ground acceleration is the maximum shaking intensity parameter in geophysics. To prevent big loss of infrastructure, dam site or multistorey buildings as well power project due to any seismic hazard, it essential mitigate damages. Seismic hazard analysis for peak was carried out hydropower Gilgit Baltistan effect hazard. Seismicity and tectonic map drawn distribution events.Study region di...

Researchers, emergency response and lifeline managers, and municipal planners are beginning to recognize the utility of seismic landslide hazard zonation. With this recognition, the decisions made based on resulting maps could have widespread social and economic impact in the event of a large earthquake. This report compares several popular permanent displacement models for assessing seismic sl...

SUMMARY Purpose: study optimization location-allocation of emergency shelter for Earthquake after destructive earthquake disaster, so as to prevent or reduce the damage caused by the earthquake and its secondary disasters, to guide the resettlement and reconstruction of post-disaster. Methods: basis on GIS, by applying the location-allocation optimization of P-center model of geographical space...

The recent studies show that the past researches may have significantly underestimated earthquake and tsunami hazard in the Makran Subduction Zone (MSZ) and this region is potentially capable of producing major earthquakes. In this study, the worst case possible earthquake scenarios of the MSZ are simulated using fully nonlinear boussinesq model to investigate tsunami hazards on the Jask Port, ...

Dynamic slope stability in open-pit mines still remains a challenging task in the computational mining design. Earthquake and blasting are two significant sources of dynamic loads that can cause many damages to open-pit mines in active seismic areas and during exploitation cycles. In this work, the effects of earthquake and blasting on the stability of the NW slope of Chadormalu mine are compar...
