Description
Summary:Active subduction off the Indian Ocean coast of Sumatra, Sumatra Subduction Zone, admits the responsibility of triggering earthquake along the boundary region on Sumatra Island. Lobu Tua Village is located near to coast Sumatra that has an underground layer in the form of Alluvium which is considered in the vulverable subsurface layer. The aim of this research is investigating the characteristics of stratification and soil properties in Lobu Tua village by using geoelectrical Data is collected from resistivity meter of ARES-G4 v4.7 SN: 0609135. Schlumberger Geoelectrical method is applied to do groundwater mapping by resistivity value at some path. The first path shows the results of electrode measurements are 6.38 meters of the base layer from the lateral surface with the area of silt soil 155 meters, may lead to land subsidence (liquefaction). The second path shows the groundwater-surface in the sounding layer is 21 meters with the potential landslides. The 2-dimensional cross-sectional model image was performed to display the cross-sectional resistivity of the rock coating method by using the Res2Dinv.
