Abstract:
Modern Probabilistic Seismic Hazard Assessment (PSHA) methods usually require seismo-tectonic information that is not readily available in many developing countries. In this study, a new event based PSHA method is developed based on instrumental seismicity and limited information on historical seismicity, geology and tectonic setting of the study region. The effect of tectonic setting is included by assigning seismic source zones associated with known major faults. Historical seismicity, when available, is integrated with instrumental seismicity to determine long term hazard. The method uses Monte-Carlo simulations to generate synthetic earthquake event catalogues with randomized key hazard parameters. The proposed PSHA method is tested using Pakistan as a case study. The results of this study compare well with the National Building Code hazard map of Pakistan, while they show more detailed local hazard distribution. This methodology is part of a wider general framework called EQRAM for ERA and mitigation studies.
