Seismic hazard assessment in Sikkim, India using MCDM models
Year: 2025
Type: article
Abstract: Seismic hazard mapping is crucial for earthquake preparedness and mitigation, specifically in the Himalayan Belt. Because several factors must be evaluated throughout the evaluation process, it can be represented as a multiple-criteria decision-making (MCDM) problem. In this study, we have applied the integrated Analytical Hierarchy Process-Entropy MCDM models to assess the seismic hazard in Sikkim, India. The findings of this study indicate that 43.20% of the total geographical area and 54.64% of the inhabitants reside under the high to very high seismic hazard level. The finding was validated using a receiver operating characteristic curve, showing an accuracy level of 64%, which is satisfactory. This work may be helpful for the government and disaster management agencies to prepare for destructive events that may occur in this belt of the Himalayas.
