The application of multi-criteria analysis followed by weighted cell-based processing is one of the methods for tsunami vulnerability mapping. In this study, vulnerability due to tsunami disaster in coastal area of East Java Province Indonesia was carried out. Appropriate input criteria were derived from Digital Elevation Model data, satellite remote sensing and survey data. The criteria applied were elevation, slope, coastal proximity, river proximity, coastal type, and land use. Five classes of vulnerability were defined from low to high vulnerability. Digital Elevation Model from Aster GDEM was applied for creating elevation and slope map, while ALOS satellite image was used in land use mapping. Moreover, vector map of East Java coastal area was used for creating coastal type, coastal proximity, and river proximity map. Analytical hierarchy process was applied in the calculation of parameter's weight, and it described that elevation was the highest weight. The area that identified as slightly high and high class of tsunami vulnerability spread in the coastal area which has a lower elevation and predict as inundated area. Most of the area was urban areas with low vegetation density. The high vulnerability areas were mostly found in the coastal area with the sloping coast type. The result presented here can aid as a basic data for city planning related to disaster mitigation and for the evacuation process and management strategy during disaster. © Int. J. of Geomate.
