VIII International Symposium

Dear colleagues!

We are glad to inform you that VIII International Symposium “PROBLEMS OF GEODYNAMICS AND GEOECOLOGY of INTRACONTINENTAL OROGENS” will be held from 28 of June to 2 of July, 2021, on the basis of Research Station RAS in Bishkek city, Kyrgyz Republic.

First newsletter with the theme of the event and a preliminary schedule

Main results of 2020

According to the complex of geological and seismological data on the northern slope of the Kyrgyz ridge (Tien Shan, the Sokuluk-Kegety interfluve), the area with increased values of signs of seismic hazard was identified.

In this area, each cell in longitude and latitude 0.25°×0.25° contains up to 360 earthquakes K>6 according to the KNET network data for 1994-2019. This number of earthquakes here is 2-10 times more than seismic events in the cells around. Also in this area there is a high density of faults with increased values of normalized Coulomb stresses and a high probability of their reactivation. According to geological and geodetic data and solutions of focal mechanisms, these faults have thrust and strike-slip kinematics, which indicates the concentration of matter. There are no earthquakes here with a significant level of stress relief as in the area around, which also indicates an increased level of seismic hazard for the selected area.

Figure. Zoning of faults by the magnitude of normalized Coulomb stresses [Rebetsky and Kuzikov, 2016] against the background of the distribution of the number of earthquakes (1994–2019) over the cells ≈20×28 km sq. (0.25°×0.25°). The focal mechanisms of earthquakes with K≥10 are marked in blue. Earthquakes with stress dropped Δσ≥10 MPa are shown as red circles. The pink rectangle is a seismically hazardous area (≈64×30 km sq.).

Laboratory of Geophysics

We’d like to draw your attention to the web page of the LABORATORY OF GEOPHYSICS on the website of the Research Station of RAS, where all relevant information on RS RAS activity within the framework of Laboratory functioning will be published.

Recall that on September 30, 2020, KNU Rector of the Kyrgyz National University Kanat Sadykov and RS RAS Director Dr. Anatoly Rybin signed an Agreement on Laboratory of Geofisics opening on the basis of the Department of Electronics and Theoretical Physics of the Faculty of Physics and Electronics of KNU. (additional Agreement of 30. 09. 2020 to the Agreement on scientific and technical cooperation between RS RAS and KNU of 23. 03.2018).
