<p align="justify"> The study of earthquake hazard microzonation is one way to anticipate the impacts caused by the response of the soil layer in certain areas to the earthquake that occurred. This study shows the response of the Bandung subsoil due to the earthquake of subduction interface (megathrust) scenario. The seismic hazard analysis used is probabilistic method using USGS (United States Geological Survey) software. The resulting map is peak acceleration in the bedrock PGA, T = 0.2 second and T = 1.0 second for probability exceedence 2% and 10% with a period of 50 years. The purpose of seismic hazard analysis is to find the magnitude of M and the distance R represents in the location under review or called deagregation. <br /> <br /> <br /> <br /> Specific sites were performed for magnitude and distance representing the result of deaggregation ie M = 8.67 and R = 141,377 km. Site specific process is done to know the dynamic parameter of soil with NSPT data from various projects spread in Bandung City area. The determination of bedrock depth for shear wave propagation process is done by microtremor array test. The process of shear wave propagation from bedrock to surface using NERA (Non-linear Earthquake Response Analysis) software then produces the top surface acceleration map. <p align="justify">
