Magnetohydrodynamic generator helps predict earthquakes
Investigations of the Earth's deep layers using a magnetohydrodynaic (MHD) generator are examined. The apparatus sends very strong (up to 2,000 A) electric current pulses into the Earth for a distance of 40 or more kilometers. Passing through different rocks, the discharge makes it possible to obtain data on their resistivity and to detect dangerous sectors among them. The possibility of this is related to the fact that the deformation of rocks prior to an earthquake changes to a lesser degree than their resistivity. A variety of seismic, geomagnetic, electrometric and seismogeochemical observations are made. These include the changes in the seismic regime, magnetic fields, variations in the chemical and gas composition of ground water. A map of seismic regionalization of the republic is constructed on the basis of the multisided investigations. It defines zones of possible occurrence of strong earthquakes and also less seismically active regions favorable for further exploitation.
