DESIGN GROUND MOTION PREDICTION FOR LAHORE AND SURROUNDING REGION IN PAKISTAN

Being second largest city of Pakistan, Lahore has emerged as a major industrial and population centre and it is growing rapidly. To mitigate the consequences of possible earthquake in future, a realistic seismic hazard assessment and design ground motion for new infrastructure is necessary. To meet this need for developers and designers in this region, design ground motion for Lahore and surrounding region is evaluated on basis of seismic hazard assessment. The most significant seismogenic sources for this region are western Himalaya and Sargodha High source zone. Peak Ground Acceleration (PGA) expected for city of Lahore with only 10% probability of exceedance in 100 years, is estimated to be 0.09g. Design Ground Motion for this expected ground acceleration is presented in the form of design response spectra and compatible time histories.
