Geomorphological study of the Leyte debris avalanche using satellite imagery remote sensing

Abstract

Geomorphologic characteristics of the Leyte debris avalanche occurred on 17th Feb. 2006 in Philippine was detected using high-resolution satellite imageries. Especially, the shape of hummocks was measured using ALOS PRISM stereo imageries, and was analyzed by GIS compared with the hammocks of Bandai Volcano. As the result, it is clear that the relationship between volume of collapse and size of hummocks between flow distance and long axis direction of hummocks.
