Deterministic Seismic Hazard Assessment for Nepal
Abstract eng: A deterministic seismic hazard analysis (DSHA) study was carried out for Nepal. The catalogue of earthquakes was updated for Nepal and the adjoining region (26°-31.7°N, 79°-90°E) from 1255 to August 2015. DSHA for Nepal was carried out by calculating peak ground accelerations (PGAs) at bedrock level over the grid of 0.2° × 0.2° (longitude and latitude) covering the entire territory of the country considering every seismic event in the updated catalogue as a point source, determining shortest source-site distances, and selecting a suitable ground motion prediction relationship. The resulting deterministic seismic hazard map indicates distinct characteristics of spatial distribution of PGA in Nepal: high hazard (0.88 g) in the north-eastern section of the country, and low hazard (0.07 g) in southern Nepal. The calculated PGA values in the present analysis are compared with the values of PGA estimated recently for the 10% probability of exceedance in 50 years and found a general agreement in the north-eastern segment of Nepal.
