Abstract
The paper presents some results obtained by transient electromagnetic (TEM) sounding. The measurements were performed in the epicenter part of Chuya earthquake of 2003, which occurred in the nearest mountain frame of Chuya tectonic depression in Gornyy Altai. Regular survey have been continued for 6 years. Electrical prospecting data obtained at the late of the 20th century on the territory of the Chuya depression were analyzed. Field investigation carried out on the territory of this depression in 1980, 2004-2006 allows time history of electrical parameter changes to be traced after great seismic event in this region.
