Abstract
By utilizing ortho images of aerial photographs taken within 3 days after the mainshock of the 2016 Kumamoto earthquake, we classified the damage of buildings into 4 damage levels. In addition, we separated the age of buildings by comparing with the National Land Image Information published by Geospatial Information Authority of Japan (GSI), and divided into wooden and non-wooden buildings with each shapes of buildings. And that, we developed approximately 320,000 GIS data by checking up with the Fundamental Geospatial Data published by GSI. In addition, we verified the accuracy of aerial photographic interpretation data with visual judgment data by field investigations. Furthermore, we generated GIS data with 250 meter square meshes which interpolated seismic intensities and damage ratios, then compared these data with 2 different ages of wooden buildings both in case of the foreshock and the mainshock of the 2016 Kumamoto earthquake.
