Its seismic potential is significant, and M>7 earthquakes occur periodically with intensive shaking in the epicenters (up to 10 points). The problem of prediction and forecasting of strong earthquakes has always been critical for this region, considering its increasing urbanization, industrial clusters and transport systems. The article describes the methodology based on rock deformation monitoring data, which aims at developing a technology capable of efficient prediction and forecasting of strong earthquakes. The technology is based on the stick-slip model developed by of W. Brace and J. Byerlee and its synergetic interpretation proposed by Ma J. et al. This model shows the preparation of the earthquake source in stages, which is reflected in deformation monitoring data. An integral property of the deformation process is its self-organization right before an earthquake. The self-organization, that always takes place before a seismic event, is considered by the authors as an inevitable shortterm precursor. All other indicators that occur randomly are considered occasional precursors. The article is focused on the methodology aspects and describes the technical details of measuring the rock deformation. It presents the proven methods of data processing with the major goal of detecting the inevitable precursor. Described in detail are the structural-geodynamic conditions of the locations of rock deformation monitoring points in the study area. The main results are based on the rock deformation records taken before three strong earthquakes in the study area – Kultuk (August 27, 2008), Bystrinskoe (September 21, 2020), and Kudara (December 10, 2020) earthquakes. The study shows that, in contrast to the inevitable precursor, the occasional precursors are manifested depending on the geodynamic conditions of the earthquake source preparation, the position of the monitoring point relative to the source, and the structural conditions of the monitoring point location.","PeriodicalId":147615,"journal":{"name":"The Bulletin of Irkutsk State University.

The geosystems of the Barguzin basin have a complex space-time differentiation connected with a long history of development and functioning in the conditions of the Baikal rift zone. The formation of modern geosystems was preceded by a long history of development, with fluctuations in natural conditions and the interpenetration of the steppe and taiga. Natural factors of differentiation of geosystems are climate aridization, increased stagnant moisture (due to groundwater), salinization. On the territory of the barguzin basin selected 13 classes of facies, typologically belong to three physiographic regions: the baikal-dzhugdzhurski mountain-taiga, southern siberian mountain taiga, central asian steppe. The article deals with the spatial and temporal differentiation of barguzin basin geosystems, which is largely determined by the establishment of the baikal rift zone, namely: the presence of in-tersecting systems of short and straight faults, modern differentiated tectonic movements, the formation of contrasting landforms, increased seismicity and dynamics of exogenous processes.","PeriodicalId":147615,"journal":{"name":"The Bulletin of Irkutsk State University.

As part of the work, the systematic correction for the study area was determined to recalculate altitudes from a digital terranean model according to SRTM topographic data to the Baltic Height System. The river width data from SRTM-based information after systematic correction are in good agreement with the width from large-scale satellite images as well as with the field width measurements at appropriate levels. The paper presents the results of the extrapolation of the rating curve, using the Chezy equation approach, the Stevens-Velikanov technique and the stage-area and stage-velocity method, using the area curve and the average depth curve obtained on SRTM materials. For each research method used in the study, by comparing with the reference of rating curve, the values of the average probable deviation were calculated. As part of the study the extrapolated rating curve is presented as an analytical equation, and the approximation error is determined.","PeriodicalId":147615,"journal":{"name":"The Bulletin of Irkutsk State University.
