Abstract Analyses of satellite radar imagery before and after the 2004 and 2005 Sumatra earthquakes reveal an overview of the uplift and submergence pattern of islands along the subduction zone and provide an outline of the regions that experienced coseismic vertical deformation. We find evidence of crustal deformation from the northern tip of the Andaman Islands to Nias Island. A line 145 km east of the trench separates western uplifted zone from eastern subsided zone. Agreement with the field observation demonstrates the feasibility of our method. We find that radar imagery analysis is more efficient for investigating vertical displacements than similar techniques using optical sensors.
