• Distribution of Building Damage in the Southeastern Part of Beichuan County by the 2008 Sichuan, China, Earthquake Based on Visual Detection of Satellite Optical Images

抄録

In order to evaluate distribution of building damage in the southeastern part of Beichuan county, severely damaged by the 2008 Sichuan, China, earthquake, visual damage detection technique is applied to pre- and post-event satellite optical images. The locations of about 5,000 buildings are identified from the pre-event image. The damage of each building is classified into three categories; complete collapse, severe damage, and less than moderate damage by comparing the pre- and post-event images. The damage ratio computed from the result of the visual detection in Qushan town, the capital of Beichuan county, is more than 80%. The distribution of the building damage shows that the damage ratios on the hanging wall of the earthquake fault is higher than those on the foot wall.
