Abstract

GMPEs are empirical equations used in seismic hazard analysis studies to predict ground motions. These GMPEs do not exit for Pakistan. In previous studies, GMPEs are adopted in different regions of the world. In this study, all the previously used GMPEs along some global ones are collected and evaluated with local strong motion data collected from different agencies. In this study, strong motion data are collected from different agencies in Pakistan. Provided data is in the wave-form that was converted into digital form for use in the analysis. These strong motion records were used to compile a strong motion catalog. By using the software, we removed the noise and put the mean removal on the wave for filtering and finding the low and high pass value.The analyses of standard deviation data show that Sharma et al. (2009) and Akkar and Bommer (2010) GMPEs results in high values of standard deviation compared to that of Boore and Atkinson (2008). This study clearly shows that internationally published GMPEs are not necessarily suitable for every region. Even a meager amount of strong motion data is used for evaluation of these GMPEs so only those conforming closer to local crustal conditions can be used for determination of seismic hazards.
