Abstract: A quick assessment method of earthquake damage loss based on Remote Sensing (RS) is introduced in the paper, which includes two parts, damage information acquisition and loss assessing. Damage information acquisition contains earthquake damage index mode and image classification mode. The former obtains macro earthquake damage of resident sites on ground through the relationship between damage index and intensity, and the latter uses digital image processing technique to gain the classified earthquake damage. The loss assessment is different according to the different modes of damage information acquisition. This method based on RS and GIS satisfies the actual demand, establishing a multi-person working mode and increasing the speed of earthquake damage assessment based on RS.

Key words: Earthquake damage, Loss assessment, Remote sensing image, GIS
