magnetotellurics

[mag‚ned·ō·tə′lür·iks]
(geophysics)
A geophysical exploration technique that measures natural electromagnetic fields to image subsurface electrical resistivity, providing information about the earth's interior composition and structure since naturally occurring rocks and minerals exhibit a broad range of electrical resistivities.

Since that time dozens of different geophysical tools have been developed for measuring resistivity, including magnetotellurics, electromagnetics, laser magnetometers and ultra-high-resolution (UHR) aeromagnetics.
The Controlled Source Audiomagnegtotellurics / Magnetotellurics (CSAMT/MT), electromagnetic (EM) surveying field work was completed on July 24, 2010 covering all of the initial survey locations previously sited by Hasbrouck Geophysics, as well as 18 additional EM stations that cover the south end of the property.
The method, called magnetotellurics, probes earthquake zones using naturally occurring low-frequency electromagnetic waves generated by solar activity and lightning storms.
