Abstract
A comparison was made of temporal variations in atmospheric pressure and soil radon concentration measured in loose sediments at three monitoring stations in the Baikal region for the period of manifestation of three fairly strong earthquakes – Bystrinsky (21.09.2020, K = 14.6), Kudarinsky (09.12.2020, K = 14.0) and Khubsugulsky (11.01.2021, K = 16.0). It has been established that the release of radon is controlled in the region by variations of atmospheric pressure. Irregularities of this dependence, first identified in the course of a formalized statistical analysis, occur for each of the studied seismic activations. They are connected with the process of preparing an earthquake, which opens up real opportunities for developing an emanation approach to medium-term forecasting.
