The weight of the vibrator is supported by rubber cushion of sand and silt, and underlain by a continuous clay-rich alluvium. For the lower frequencies, the conventional vibrator and pad that simulates a wheel load are used. Lateral profiling with the EM3 I and EM34 terrain conductivity It was found that if the transducers are located at & 0.5 x from meter was conducted atop the dike. Nazarian and Stokoe have been using the source but generally less than 9 m. Apparent terrain conductivity is extremely placed at 5 1.5 X.
Some of the places in which MT is used include volcanic-covered areas, overthrust belts, and rift zones.
