Geophysical Survey Methods

Geophysical survey methods are techniques used to explore and map underground features without digging. They involve measuring physical properties like ground density, magnetic fields, electrical conductivity, or seismic vibrations to detect differences in underground materials. Common methods include ground-penetrating radar, magnetic surveys, electrical resistivity, and seismic surveys. These tools help identify buried objects, rock layers, water sources, or archaeological sites by interpreting variations in the data collected. They are valuable for engineering, environmental studies, resource exploration, and archaeology, providing a non-invasive way to understand what lies beneath the Earth's surface.
