Tsunami Effect in Nanggroe Aceh Darussalam and North Sumatra Provinces, Indonesia

In relation to identifying the destructed area in Nanggroe Aceh Darusslam (NAD) and North Sumatra, as the result of quake and Tsunami on 26 December 2004, LAPAN - the National Institute of Aeronautics and Space of Indonesia - and other institutions in Indonesia, such as Indonesian Soil Research Institute (ISORI), and Agency for Assessment and Application of Technology (BPPT), have conducted damage assessment of affected area. Remote sensing data, field observation, and CS techniques have been combined to identify the destructed area. Visual interpretation of Landsat TM and IKONOS and simulation using DEM has been exercised for the activities. The result shows that a total length of coastline corridors destructed by tsunami in NAD and North Sumatra is about 600 km to at least 1 km inland. Total area destructed is 120,295 ha, 21.5 % of which is settlement and 272% is agricultural lands with various level of damages and several types of causes. Field observation indicated that a dense coconut trees or. and palm oil trees corridor of 100-200 m width is the potential of vegetation belts to reduce devastating effect of tsunami occurred along coastline.Hlm. 1-1
