DEVELOPMENT OF GIS DATASET FOR DAMAGE DISTRIBUTION ANALYSIS AFTER THE 2010 CHILE EARTHQUAKE

Abstract

This paper presents the results of field survey conducted by the authors after the 2010 Chile earthquake. The authors visited the affected area about a month after the earthquake occurrence. The GIS datasets for building damages in Talca and tsunami inundation areas are constructed in this study and a series of fundamental analyses are performed using the digital elevation model (DEM). In addition to that, the availability of satellite images captured after the earthquake to detect damaged buildings in Talca is discussed using the GIS data constructed in this study.
