Determination and Mapping of the Causes of High Risk of Earthquake Hazards Using Geoelectrical Data in Bengkaung, Batu Layar, West Lombok Indonesia

The Bengkaung area, Batulayar District, West Lombok is suspected to be very vulnerable the risk of earthquake hazards. However, in this area no scientific research, either geological or geophysical, has ever been carried out regarding hazard. How are physical characteristics lithology and structure disaster? purpose study was determine subsurface structures that were validated by level damage. method used geoelectric local building damage data. results 2D anomaly modeling show lithological layers form sand, sandstone, clay, andesite lava faults, fresh lava, granite. fault detected center a north-south direction. Earthquake hazard analysis shows cause high Village presence faults cohesive lithology. highest potential southern part Village. ​​Bengkaung dominated clay properties, especially on surface. western northern parts have medium low vulnerability last two areas non-cohesive soils sandy lapilli pumice
