FIELD: instrumentation.
SUBSTANCE: invention refers to the methods of detecting the forerunners and can be used to identify the possibility of earthquakes in the Baikal Lake region. The invention concept is as follows: water samples are taken from the zone of intersection of deep breaks in the Baikal Lake territory where earthquakes of different intensity took place repeatedly. Sampling is performed by a water intake structure comprising a deepwater intake (8), an electric pump (9) set at the water intake station on the Baikal bank, filters for coarse (10) and fine (11) treatment of water. Concentration of helium dissolved in the deep water is examined. A conclusion on possible earthquake is made on the basis of the curves of the helium concentration variation.
EFFECT: detection of a possibility that an earthquake will occur.
