Abstract
A huge magnitude 9.0 earthquake occurred besides western coast of Sumatra Island, Indonesia on December 26, 2004. The earthquake created the huge tsunami in many countries along Indian Ocean, such as Indonesia, Sri Lanka, Thailand, India and so on. Tsunami disaster damage in Banda Arch province of Indonesia is one of most serious events in the world. In order to assess the tsunami disaster damage, a scene of Disaster Monitoring Consortium (DMC) satellite image received on January 7, 2005, after the catastrophe, and several Landsat7 ETM+ images received before earthquake were collected. Based on Remote Sensing and GIS technology, the tsunami disaster monitoring and quick assessment have been carried out. The result shows that the western coast of Sumatra Island in Arch province, near earthquake center, suffered more seriously from tsunami disaster, and the eastern coast damage is insignificantly. In the whole Arch province, the loss of Banda Arch city, capital of Arch, is most serious. About 483 square kilometers area had been flooded due to tsunami in western coast of Sumatra island of Arch province, including 26 square kilometers urban building area, 430 square kilometers rural area and 27 square kilometers water area, such as wetland, lake and pond. In the end, Digital Elevation Model (DEM) is used to analyze the relation between terrain and tsunami destruction. The result shows that the elevation of flooded area due to tsunami, in general, is below 20 meters.
