An electrical resistivity study was conducted at the selected study area to ascertain the causes leading to land instability after a portion of the area was washed away in 2005 at site 1(Officer’s Hill) and in 2007 and 2008 at site 2 (Merhülietsa). The data generated through Vertical Electrical Soundings (VES) at five VES stations were analyzed and interpretation of the sounding curves indicated the presence of three to four subsurface geo-electric layers comprising of the topsoil, fractured shale layers/shale with sandstone/siltstone intercalations, and weathered shale layers with high water content. The dominance of K type curve confirms that the study area has lower saturated bedrocks consisting of sheared, crumpled, weak, and highly weathered rocks that are in various stages of weathering and are more prone to slope failures.
