Deterministic seismic hazard analysis for Peshawar, Pakistan
نویسندگان
چکیده
Ground motion estimation for a site (34.01 o N, 71.45 o E) located in the Peshawar in terms of Peak Ground Acceleration (PGA) values is conducted. It is carried out with deterministic seismic hazard analysis approach using faults sources within a radius of one hundred kilometers around site. The results of this study indicate that the Main Boundary Thrust located at a distance of twenty nine (29) kilometers from the site with a maximum potential moment magnitude of 8.1 is potentially the most seismogenic source for an earthquake in the region. Such a scenario earthquake may generate a design earthquake with PGA values of 0.232 g in Peshawar. PGA map for area surrounding the site (33.75 o -34.15 o N; 71.29 o 71.50 o E) is also developed in this study. This map shows that the peak-ground acceleration values are highly variable around the site.

Seismic hazard assessment like many other issues in seismology is a complicated problem, which is due to a variety of parameters affecting the occurrence of an earthquake. Uncertainty, which is a result of vagueness and incompleteness of the data, should be considered in a rational way. Using fuzzy method makes it possible to allow for uncertainties to be considered. Fuzzy inference system,...
