Detection of Building Damage Areas Due to the 2006 Central Java, Indonesia Earthquake Using High-Resolution Satellite Images

Abstract eng:
Rapidly quantifying extent and severity of building damage is a high priority in an aftermath of a large earthquake. In this study, a semi-automated damage detection technique is applied to high-resolution satellite optical images observed before and after the 2006 Central Java, Indonesia earthquake (Mw6.3). The satellite FORMOSAT-2 images whose spatial resolution is 2m are used. In the damage detection, the difference of digital numbers between pre- and post-earthquake images is mainly utilized. The distribution of the pixels detected by the proposed method is compared with actual damage distribution evaluated from the result of visual detection of satellite images and the damage statistics. The result shows that the distribution of the detected pixels approximately corresponds to the severely damaged areas.
