Geology and the deformation of potential limestone geohazard by using Electrical Resistivity Imaging(Eri) survey At Kampung Jias, Kuala Betis

Limestone are very soluble rock which causes it easy to formed karstic feature such as cavities, caves, solution slots, pinnacled bedrock, stalactites or stalagmites and basal notches overhang cliffs. A major fault and joint are structurally controlled most of sinkhole and cave.While 45 % of the study area consist limestone. This research was conducted to study the geology and the deformation of potential limestone geohazard by using electrical resistivity imaging (ERI) at Kampung Jias, Kuala Betis. The main objectives of the study were to produce the geological map of study area with the scale of 1:25 000 and to determine the potential of limestone geohazard in the study area using ERI. Method was being used in this study is by using geological mapping to identify the geomorphology, lithostratigraphy and structural geology of the study area. The rock unit exist in the study area is limestone, tuff and metasediment rock which is phyllite.. The formation of the study area is Gua Musang formation. While potential of limestone geohazard being determined by using ERI. The equipment has been use in ERI survey is ABEAM, 2 cable and electrode. Three survey line has been run in the study area. The result is Line 1 and Line 2 has low possibility for limestone to occur. While line 3, that used pole dipole principle might has high possibility of sinkholes to occur. The conclusion geological map with scale 1:25000 managed to being produced and in the study area has possibility sinkholes to occur.
