| Abstract | The occurrence and evolution of sinkholes in the Khorat and Sakon Nakhon basins in northeastern Thailand call for scientific explanations, particularly in the areas where there is continuing pumping of brine solution for salt production. Residents near pumping areas have been living with fear of hazards due to collapse of subsu rface cavities into sinkholes. Identification of su bsurface cavities in sinkhole -prone areas could relieve such fear. A two - dimensional resistivity survey was conducted in areas near the sinkholes at Ban Non Sa Bang, Ban Muang District, Sakon Nakhon Province. This survey proved to be suited for detection of a cavity near the ground surface. The cavity was considered as a lateral anomaly in a homogenous medium. The anomalous zone of the cavity could be distinguished as a 0.1 to 0.5 ohm-meter low resistivity zone surrounded by a higher background resistivity. The survey results indicated that a two-dimensional resistivity survey can be used as a basic tool for identifying a near -surface cavity in sinkhole-prone areas in the Khorat and Sakon Nakorn basins. |
