Electro-Magnetic Surveying

Electromagnetic (EM) surveying is a technique used to detect and map subsurface features by measuring how electromagnetic fields behave underground. It involves sending electromagnetic signals into the soil and recording how they are affected by different materials, such as minerals, water, or voids. These measurements reveal variations in electrical conductivity, helping geologists and engineers identify mineral deposits, groundwater, or structural anomalies. EM surveying is non-invasive, quick, and widely used in resource exploration, environmental assessments, and engineering projects to gather detailed subsurface information without digging or drilling.
