Özet
The Lake Van basin and its surroundings (36,500 km(2)) in the eastern Turkey have not been investigated adequately in terms of earthquake vulnerability, and pre-earthquake preparedness. In this study, a digital terrain model (DTM) of the Lake Van region was developed combining an ASTER digital elevation model (DEM), Landsat-7 ETM+ imagery, remote sensing techniques, and geographical information systems. Terrain characteristics derived from DTM with DEM, and a 3-D land-use and land-cover fly-through view such as fault zones, drainage patterns, lineaments, and landforms were interpreted in terms of earthquake vulnerability. Our results indicate that the directions of Mus-Tatvan (Mus thrust), Bitlis thrust, and ErcisPatnos-Malazgirt-Varto-Karliova along with Van and Ercis possess the highest risk of earthquake hazards.
