A Probabilistic Seismic Hazard Analysis (PSHA) was conducted to access the seismic risks associated with the power house site and this process assisted us in creating a hazard curve. Peak Ground Acceleration (PGA) is calculated for a range of earthquake event levels and return periods. The PGA, for this site is determined to be 0.55g for the design basis earthquake (DBE) for a 475-year return period. A site-specific response spectra specifically for design basis earthquakes (DBE) was constructed in order to compare the result with the response spectra from the Indian Standard (IS 1893:2016) and the Nepal Building Code (NBC 105:2020). The calculated PGA value is found to be greater than the PGA value mentioned in NBC 105:2020 for the power house site.
