The phenomenon has also captured the imagination of authors, finding its way into fiction. These currents exhibit diurnal patterns, flowing towards the Sun during the day and towards the poles at night.īoth telluric and magnetotelluric methods exploit these currents for subsurface exploration, aiding in activities like geothermal and mineral exploration, petroleum prospecting, fault zone mapping, groundwater assessment, and the study of tectonic plate boundaries. The Earth's crust and mantle are host to telluric currents, with around 32 mechanisms generating them, primarily geomagnetically induced currents caused by changes in the Earth's magnetic field due to solar wind interactions with the magnetosphere or solar radiation's effects on the ionosphere. These currents have extremely low frequency and traverse large areas near or at the Earth's surface. Natural electric current in the Earth's crustĪ telluric current (from Latin tellūs, "earth"), or Earth current, is an electric current that flows underground or through the sea, resulting from natural and human-induced causes.
