Magnetotellurics

Magnetotellurics (MT) is a geophysical method used to explore the Earth's subsurface by measuring natural electromagnetic fields. It detects variations in electrical conductivity, which helps identify different geological materials and structures underground. By placing sensors on the surface, MT captures signals from natural sources like lightning and solar activity. These signals reveal how the Earth's materials respond to electric and magnetic fields, providing valuable information about resources, geological formations, and even potential hazards. MT is particularly useful in areas lacking detailed geological data, making it a crucial tool in mineral exploration and environmental studies.
