An Overview on the Seismic Hazard Analysis of Gujarat

The present research paper reviews the progressive development of the seismic hazard analysis of the Gujarat region. In peninsular India, Gujarat and its neighboring states witnessed frequent earthquakes that can be categorized as deadly and damaging, although they were located far from any plate boundaries. In India, the zonation map has been modified and updated regularly. Seismic zonation was done at the national and regional levels, considering different approaches. A thorough investigation of the local site characteristics in terms of geological, geophysical, and geotechnical qualities, including microzonation studies, is required to address the issue of seismic hazards. The various methodologies have limitations adopted in the literature to carry out seismic hazard analysis and site-specific studies in Gujarat. The seismic hazard analysis is a very essential procedure to develop a microzonation map of the region. Peak ground acceleration values at the bedrock level can be determined by hazard analysis. This paper is about how different researchers tried to find earthquake risks in different parts of Gujarat using different methods.
