Detection of cavities in Kuala Lumpur Limestone using geo-electromagnetic method

Cavities in Kuala Lumpur Limestone have been known to have caused problems, such as sinkholes, subsidence, slump zone, and other geohazards. Hence, the main purpose of this study had been to detect cavities in limestone with the application of Geo- Electromagnetic Method using EM 34-3 equipment in K...
