Abstract

Since Indonesia is located on the equator, causing it has a high annual rainfall approximately about 3500 mm/year. In addition, Indonesia also has many mountainous areas that causing it has a steep topography and also a various geology condition in each region. Those two factors are indicated as a trigger of natural landslide disaster. Another factor that also triggers the occurrence of the landslide is the changing of land function on catchment areas and slopes. The landslide disaster in Indonesia is increasing continuously in the last decade with the number of the event reach up to 3875 events. For example, in 2014 in Trangkil, Semarang City, the landslide was occurred and destroy at least 32 houses, and in the same year in Gombel Lama, Semarang City, 21 peoples were found buried by the landslide. In 2016 in Bukitsari Housing, landslide causing two peoples dead due to the collapse of the retaining wall. This research was conducted to visualize the form of the subsurface of soil layer by comparing the result of geo-resistivity and geological map that could be used as a reference to determine the location of the slips field.
