Study of Methodology for Classifying Local Characteristics of Disasters by Earthquakes

Abstract

This paper aims at developing a scheme to classify the local characteristic of disasters by earthquakes. First, we create the numeric indices which show the potential of the disasters. Second, conducting cluster analysis we classify typical areas in damage feature, such as Urayasu City hit by liquefaction due to 2011 Tohoku Earthquake, into seven characteristics. Finally, we classify other areas by conducting discrimination analysis to verify the method. We find that results derived from the method well classify overall damage situations due to earthquakes that hit in Japan during recent years.
