TIME SERIES MAPPING UTILIZATION ON THE SUSCEPTIBILITY ASSESSMENT OF SAN POLICARPO, EASTERN SAMAR, PHILIPPINES

Abstract

To assess changes in typhoon susceptibility in San Policarpo, Eastern Samar, the study compared and mapped Typhoon Hagupit before and after. Understanding the susceptibility dynamics through time can help reduce the likelihood of deaths and other losses. The central research questions were: Which barangays were most susceptible in both years? What has changed since Typhoon Hagupit? How did government resilience efforts affect susceptibility? Using catastrophe risk reduction approaches reduced susceptibility from 2010 to 2015. San Policarpo census statistics were used to assess 17 barangays (2010 and 2015). The researcher created an index that measured sensitivity, exposure, and adaptive capacity (Krishnamurthy et al., 2014). The susceptibility index scores were compared to depict geographical dynamics. The outcome was that susceptibility fell to a low level. This drop could be attributed to recovery operations after Typhoon Hagupit.
