Abstract
This layer provides the 475 year return period PGA (peak ground acceleration) measured in g for earthquake ground shaking. This dataset was derived from an area and fault source model for Nepal by using a detailed earthquake catalogue aggregated from sources including NGDC, ISC-GEM, ANSS, and many historic catalogues and papers. Outputted at 1km resolution. A standard hazard modelling process has been used employing Mmax; site effects; a-b values; and GMPE combinations. It should be noted that many different models are possible as part of the PSHA process and this represents the best fitted regional model. This should only be used for indicative purposes.
