Seismic Hazard Assessment in Ranau: Analyzing Earthquake Risks from the Mensaban and Mesilou Faults, Malaysia

Sabah, Malaysia, is subject to frequent seismic activity, with moderate earthquakes occurring periodically. This study aims to assess seismic hazards in the Ranau region, focusing on the Mensaban and Mesilou faults using Probabilistic Seismic Hazard Analysis (PSHA). The study analyzed data from 1900 to 2020 to estimate peak ground acceleration (PGA) values for both 10% and 2% probabilities of exceedance, categorizing the region into various earthquake hazard zones. The results indicate significant variations in seismic risk across the study area, offering essential insights for improving disaster preparedness, land use planning, and the development of earthquake-resistant infrastructure.
