Prediction and Evaluation of Earth Flow Disaster in Hiroshima Using Satellite Remote Sensing

Abstract

In Hiroshima there are many steep slopes. Recently, the development of the mountain slope has brought up the possibility of earth flow disaster. Therefore, the risk prediction technique has become a necessity. In this paper, the earth flow disaster, which occurred in Hiroshima on June 29, 1999, was examined using artificial satellite data of wide area. The satellite information data showed the usefulness of the risk prediction technique in forecast the slope torrent of mountains. Furthermore, the accuracy confirmationof the earth flow disaster prediction technique by using the satellite data showed the effectiveness of the future application.
