RAPID SEISMIC RISK ANALYSIS OF MAJOR CITIES OF INDIA USING DEMOGRAPHIC DATA

Abstract

dissertation is presented to contribute towards disaster management and earthquake risk studies. This study is done for 48 major cities of India keeping in mind that risk is always greater for the regions with large populations, India being the second most appropriate example in this regard. This study is based on another earthquake risk assessment technique done for 23 cities in Turkey and was developed by Kepekci and Ozcep [6]. The objective of their method, very similar as ours, is to estimate earthquake risk levels. In this study, the earthquake risk was a function of population, number of household’s and ground motion level. All the demographic data has been obtained from India Census 2011 and all the Ground motion data is attributed to national disaster Management authority of India. Maximum risk was estimated for Delhi and risk rating were estimated for all the cities under the study. Other cities where the risk was found to be highest are Mumbai. Asansol, Kolkata, Ahmedabad and Jaipur (Descending order of risk).
