Radioprobing of underground structure of the Failure Gulf, formed as a result of the M7.5 Tsagan earthquake

The Failure Gulf of the Baikal Lake was formed after a strong earthquake when dry land was lowered under the Baikal Lake water. Geoelectric characteristics of the seismotectonic structures of the studied region are described. Now the foundation of the gulf continues to depress. A border between modern bottom sediments and “paleo-soil” was revealed by means of method of radioimpedance sounding. Underground structure and electrophysical properties of the Failure Gulf of the Baikal Lake are defined.
