The preliminary regional seismic hazard map for Pakistan and adjoining regions published by Sarwar et al. (2018) is here updated. The earthquake catalog by Khan et al. (2018) is adopted, and the latest computer codes for the neo-deterministic seismic hazard assessment (NDSHA) are used. At the regional scale, NDSHA is based on the generation of synthetic seismograms at a regular grid of 0.2 degrees × 0.2 degrees. The main input is a set of earthquake sources and layered anelastic structural models. As a result, seismic hazard maps are produced in terms of maximum displacement (Dmax), maximum velocity (Vmax), and design ground acceleration. The comparison between probabilistic (PSHA) and NDSHA maps for Pakistan shows that the currently adopted PSHA maps generally underestimate the level of ground shaking that might be expected for future events.
