ABSTRACT
Probabilistic seismic hazard analysis (PSHA) has been carried out for the district of Jalandhar. The earthquake data has been collected from different seismological agencies, e.g. NDMA, IMD, ISC-UK and USGS, and a comprehensive earthquake catalogue has been developed. Several ground motion prediction equations have been reviewed to select a GMPE appropriate for carrying out PSHA. Earthquake hazard parameters have been estimated for PGA and spectral acceleration. The seismic hazard maps of district have been developed for different return periods at 10%, 2% and 1% probability of exceedance. The results show that the district can experience strong shaking from earthquakes originating in north-west Himalayas. Nonlinear site response analysis has also been carried out for limited number of sites in order to investigate the effect of local site conditions on earthquake ground motions. It has been observed that the soils of district of Jalandhar are capable of amplifying earthquake ground motions. Therefore, structures must be designed using the hazard parameters determined considering the local tectonic setup of the region as well as the local soil conditions. The developed hazard maps would help engineers and architects involved in planning and design of earthquake resistant structures and retrofitting works.
