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.).

The election of Director of the Federal State Budgetary Institution of Science Research Station of the Russian Academy of Sciences in Bishkek city (RS RAS)

On October 28, 2020, the General Meeting of Employees of RS RAS was held. The main issue on the agenda was the election of Director of RS RAS.

The election procedure was carried out in accordance with the RS RAS Charter and the Regulation on the procedure for the Director election of RS RAS

Earlier, by Order of the Ministry of Science and Higher Education of Russia No. 386-p of October 19, 2020, two candidates were approved for the post of director of RS RAS:

1) Dr. Pavel ALEXANDROV;

2) Dr. Anatoly RYBIN.

Olga Zabinyakova, Scientific Secretary of RS RAS, was elected as a Chairman of the General Meeting of Employees. Also, by RS RAS order, the Election Commission was appointed, which was headed by S.S., Acting Head of the Laboratory for Integrated Research of Geodynamic Processes in Geophysical Fields, candidate of Physics and Mathematics Sanzhar Imashev.

The total number of RS RAS staff members included in the voting list was 137 people. The number of registered election participants was 109 people, including 2 employees of the Representative Office of the RS RAS in the Russian Federation who voted by e-mail (quorum was observed).

Both candidates presented their election program, including the development program of RS RAS for 2020-2025 years. After that, a debate took place during which RS RAS employees had the opportunity to ask questions to candidates and speak out in support of one of them.

A secret ballot procedure was held, after which members of the Election Commission voiced the election results: 29 votes for candidate Pavel ALEXANDROV, 79 votes for candidate Anatoly RYBIN. Thus, the vast majority of votes was casted for Anatoly RYBIN.

Congratulations to Dr. Anatoly Rybin on his victory in the elections for the post of Director of the Research Station of the Russian Academy of Sciences in Bishkek city!

Management and staff of the Kyrgyz National University named after Zh. Balasagyn congratulate Dr. Anatoly Rybin with contested victory for the post of RS RAS Director!

GMTS News

From 23 September to 07 October 2020, in continuation of monitoring observations carried out since 2012 on the territory of the Bishkek geodynamic test site, along the "East" and "Centr" profiles of the Kentor using the Phoenix MTU-5 measuring complexes, by the MTS group consisting of three teams, MT-soundings were performed at 30 points of the Centr (C1-C4, C6-C11) and «East» (E1-E11, E13-E21) profiles.

The beginning of the work was preceded by the calibration of the recorders and sensors of the MT stations. At all observation points, a control record of at least 40 minutes was preceded to assess the level of interference and adjust the parameters of recording the working record. The electric components of the MT-field were measured using measuring devices with electric dipoles 50 m long. Magnetic field components were measured with using of MTC-50 induction sensors. The dipoles were earthed by nonpolarizable electrodes by the “electrode to electrode” principle with previous observations at all sounding sites. The orientations of the measurement setups completely repeated the previous deployments. The duration of the MT-field registration at each observation point was 15-16 hours.

In the period from 23 September to 02 October 2020, the brigade № 3 of the MTS group carried out work on magnetotelluric sounding (MTS) on the "Boom" profile, located in the area of ​​the Zholbulak village, Kemin district. The number of observation points was 9 (FT1 - FT9). The work was carried out with a Phoenix MTU-5 station in the regular registration mode. The beginning of the work was preceded by the calibration of the recorder and sensors of the MT station. Duration of registration of the MT-field at each registration point is more than 14 hours. Upon completion of work on this profile, the team from 02 October to 07 October 2020, together with two teams of the group, continued to perform work on the "East" profile of the Kentor.

LAHD news

In accordance with the research plan (topic code FMNN-2019-0004, state registration number AAAA-A19-119020190065-6), LAHD continued work on the creation of a modern hardware and software measuring complex for conducting electromagnetic sounding of the earth's crust using the TEM method using pseudonoise sounding signals.

In September this year, LAHD employees carried out a series of field experiments with a manufactured experimental sample of the measuring complex. The main tasks solved in the process of experimental work are further development of the technology for conducting field measurements, improvement and debugging of algorithms and software for data processing. The goal is to obtain high-quality curves of the field formation in a wide dynamic (≥ 150 dB) and frequency (0.2 ÷ 40,000 Hz) ranges of recorded signals. Field experiments were carried out at the near test point "Polygon, MGD".
