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 ...

Hazard Analysis and critical Control Point system is a preventive tool for assuring the safe sound manufacturing of foods products. It’s based totally on common utility technical scientific standards to meat process.

the percent of normal precipitation index (pnpi) is a widely used drought index to provide good estimations about the intensity, magnitude and spatial extent of droughts. the objective of this study was analyzing spatial pattern of drought by pnpi index. in this paper, according to the data of 40 stations in iran, during 1967-2009, the pattern of drought hazard is evaluated. influenced zone of ...

the identification of natural hazard prone areas for future planning requires an efficient decision support tool to provide the appropriate weights for the various topographical, geological, and seismological factors responsible for the expected hazards. in the present study, an analytical hierarchy process (ahp) with six earthquake hazard parameters (ehps) was used as a decision support system...
