The determinant of slip plane and volume potential of landslide mass using resistivity data in Air Kuning Batu Merah, Ambon City

Abstract

To reduce the risk of landslides and to be aware of areas that have the potential for further landslides, detailed measurements of these zones are required. Measurements were made to identify a sliding plane below the surface using the geoelectric resistivity method of the Wenner-Schlumberger configuration. The resistivity data from the interpretation results are used to determine slip plane’s slope and the potential for landslide masses. The research location is on steep hills in Air Kuning Batu Merah, Ambon City. The results showed that the slope angles for line-1 were 4.20 degrees, line-2 was 17.60 degrees, line-3 ranged from (22.80 - 23.20) degrees, and line-4 was 21.80 degrees. Furthermore, the estimated volume potential of landslide mass based on the cross-section of subsurface resistivity is 3,063.88 m3. With an indication of a landslide field, the slope has the potential for a subsequent landslide if affected by external and internal factors.
