Ryoichi Yanagawa, Shigeki Sakai

Abstract


The estimated tsunami height and inundation depth in March 11th, 2011 were shown and geographically analyzed. The spatial distribution of tsunami inundation and its height were visualized with GIS, and regional characteristics of representative areas were spatially examined. Considering the spatial distribution of inundation area, depth and house damage, it was separated by three groups having a similar characteristics. The zonal classification by house damage and typical inundation depth were clarified the regional features and differences.
