The report presents the results of studies of the characteristics of the deformation signal during the preparation of regional earthquakes according to laser deformation measurements in the adit of the Talaya seismic station (Baikal region). Studies have shown a number of features during the deformation process on the eve of regional earthquakes. The deformation data recorded on the seismic station (? = 51°40`48``N, ? = 103°38`24``E) during the period from 1994 to 2015 were used as experimental material. During th...

Continuous measurements of deformations of the Earth's crust make it possible to record changes in their character in several characteristic parameters. Such parameters include the amplitude, phase, and frequency of periodic oscillations, for each characteristic frequency separately, as well as random typical or atypical artifacts. All this information with proper processing can be used for various purposes, one of the most important tasks in this case is to reliably identify earthquake precursors. These studies r...
