Analysis of tsunami disaster mitigation priority on urban area settlement

Abstract

Abstract Settlement in coastal areas is at risk of a tsunami disaster. In urban areas, the risk of disaster can be greater than the area behind it. This study aims to analyze the priority of tsunami disaster mitigation based on settlements criteria in urban areas. The data collection technique uses a questionnaire given to experts in the field of disaster mitigation. The research variables consisted of occupancy typology, settlement locations, settlement patterns and density, coastal environment, evacuation routes and evacuation sites. Processing and analyzing data using statistical product and service solution software. The results of the regression analysis obtained that the settlement model Y = 3,055 – 0,410 residential typology + 1,119 settlement locations -0,017 settlement patterns + 1,323 settlement density + 0,040 coastal environment + 0,853 evacuation routes + 0,875 evacuation places. A high correlation was obtained on the location criteria and settlement patterns. Based on the mean value, the criteria for vertical evacuation places have the highest value, so can be recommended as a priority for the tsunami mitigation plan in urban settlements.
