The possible landslide in Kg. Chuchoh Puteri, Kuala Krai, Kelantan were investigated using the electrical resistivity imaging (ERI) technique. The survey for the collecting of data was conducted along six lines. Each survey line was 200 meters long, with 5 meters between electrodes. ABEM Terrameter LS 1 is used to record all the data and RES2DINV software is used to process it. While conducting the geophysical survey, the relationship between resistivity and conductivity is reciprocal. A pole-dipole array configuration was utilised in survey Lines 1, 2, 4 and 5 and in survey Lines 3 and 6, a Schlumberger array configuration. Survey Lines 2, 3, and 6 are primarily indicated as having a high probability of experiencing a landslide using the pseudosection 2-D profile. The findings reveal varying resistivity at a depth of study between 40 and 80 meters for a survey line length of 200 meters. In general, the resistivity survey's seven pseudosections showed two distinct types of soils: dry residual soil (1 1500 ¦m) and weathered volcanic rocks (>1500 ¦m). Residual soils with varying saturation levels, hard soil and weathered volcanic rock, have dominated the soil profile. These profiles can generally be divided into two (2) zones: thin/thick layers of loose to dense residual soils (10 100 ¦m; Zone A) and thin/thick layers of dense and hard material (> 1000 ¦m). © The Authors, published by EDP Sciences.
