Abstract

A great Indian Ocean earthquake occurred in 2004 had caused uplift and subsidence with various rates in Sumatra and Indonesia. The post-seismic land vertical motion apparently changed land formation and coastal topography. However, it's usually difficult to quantify how coastline has changed after an event in a short time and with low cost. In this study, we utilize historical Landsat images in this region to first compose an inundation chance model along the coastal zone. This model is then converted into digital elevation model by giving height references (upper and lower boundaries) from NAO.99b tide model. The vertical motion in a range of few tens of centimeters can be seen in several tidal flats potentially caused by this megathrust earthquake.
