This site discusses magnetotelluric (MT) method used to image the earth structure. The method was pioneered by Andre Tikhonov in Russia and Louis Cagniard in France back in the 50's. Today, the applications of the method spans a very broad spectrum, such as  oil industries, engineering, geothermal, crustal studies, volcanoes, environmental studies. This site is decicated to the magnetotelluric theory and applications, and hopefully we can share thoughts and ideas, especially for geothermal applications.
