Impact craters are the dominant geographic features on many solar system object in planetary bodies. Geophysical studies in geographic features may assist in studying of deformation and fracturing of the rock. 2-D resistivity imaging method is one of the geophysical method applied in subsurface study for meteorite impact at Bukit Bunuh. The study line was WE direction, perpendicular to Sungai Perak and two mountain ranges, Bintang Range and Titiwangsa Range. A survey line of 2.065 km was done

The first zone is with resistivity value of 10-800 ohm-m and 3000 ohm-m with thickness 5-60 m. The second zone with resistivity value >3000 ohm-m was granitic bedrock. A lot of fracture and fault were identified within the granitic bedrock and other potential areas of poor rock quality.
