Abstract
Tsunami induced by Sumatra earthquake (Mw = 9.0) damaged in the coastal countries of the Indian ocean. It was expected that the seismic strong motion caused damages in structures. However, there was little information on them, because tsunami washed damaged structures completely. The investigation of the structure damages due to seismic motion was carried out in Banda Ache, Indonesia. This paper focused on damages in geotechnical disaster such as liquefaction, slope failure and subsidence of land. Swedish weight sounding was carried out in the region where ground deformation was observed. Mechanisms of ground deformation were discussed.
