Abstract
The 2-D geoelectrical resistivity survey investigated the subsurface cavities in Tamot district,
Phatthalung province. The electrical resistivity survey of 2D-ERI was used by the wenner configuration
with 10 m of the electrode spacing, 120 m of maximum depth for 21 levels and a line survey length of
700m. The result showed the electrical resistivity anomaly for the detection of three sinkholes and
two limestone cavities. The dimension of the three limestone cavities was about 20-30 m. The
sinkhole and limestone cavities were characterized to be geological structure in this area.
