Geodynamic processes occurring in active regions of the planet are manifested in various geophysical fields. The task of monitoring the processes of cracking is urgent, and the successful separation of the magnetotelluric field into endogenous and exogenous components allows us to detect the moment of activation of cracking. The solution of the problem of locating the activated volume is possible with the help of a three-component gradient installation for recording the seismoacoustic field near the day surface.

An article entitled «VOLUMETRIC AND SPATIAL SEGMENTATION OF THE TIEN SHAN LITHOSPHERE ACCORDING TO GEOPHYSICAL DATA» by the research team of the authors of the Laboratory of Deep Magnetotelluric Research of the RS RAS (Rybin A.K., Bataleva E.A., Nepeina K.S., Matyukov V.E.) is published in the scientific journal «Geodynamics & Tectonophysics», indexed by the international Scopus database of the third quartile (Q3).

The geological and geophysical materials on the deep structure of the crust and upper mantle of the Central Tien Shan were collected and analyzed under Project 16-17-10059 supported by the Russian Science Foundation. For the comprehensive analysis of geological and geophysical information, the data on the Northern Tien Shan were prepared under the state assignment of the Research Station RAS in Bishkek for 2019–2021, which was funded by the RF Ministry of Science and Higher Education (project АААА-А19-119020190063-2).

Regional GNSS measurements in Kyrgyzstan in 2021.

   This year, employees of GPS laboratory (RS RAS) conducted routine field measurements of the Kyrgyz GPS network sites based on the Global Navigation Satellite Systems (GNSS) method. Annual repeated surveys of the same GPS sites on the study area allow to fix the high-precision position of the site at the measurement time and to track the multi-year rate of its displacement to solve fundamental geodynamic problems, as well as to assess the danger of the population and vital objects.

   From May to September 2021, two campaigns (KGS21a from 25.05.2021 to 25.06.2021; KGS21b from 17.08.2021 to 15.09.2021) were carried out for measure regional sites on the territory of Kyrgyzstan (Fig.1).

News of Electromagnetic observation Group of LIS RS RAS

The staff of Electromagnetic observation Group of Laboratory of Integrated Studies of Dynamic Processes in Geophysical Fields (EOG LIS) carried out a series of experiments for registration of variation of the total intensity of geomagnetic field during the periods of electromagnetic soundings with ERGU-600-2 system.

The proton magnetometer MV-07 is used as a recorder, which has a measurement range of 20-100 μT and resolution of 0.01 nT with data storage in flash memory of the device in a binary format.

The measurements were carried out with a sampling rate of 5 seconds and a duration of 6 hours during the ERGU-600-2 operating sessions.

Field work of the Magnetotelluric Research Group (DMTS)

In the period from July 13 to July 24 2021 the MTS group consisted of 4 teams carried out detailed works on the profile "Boom", located near the Zholbulak village of, Kemin raion. Three teams conducted magnetotelluric sounding (MTS) on 16 points of the profile, where the duration of registration of MT field in MTS mode at each observation point was 16-20 hours and on one observation point in DMTS mode, duration of observations was 180 hours. The work was carried out by means of Phoenix MTU-5 and MTU-5A measuring complexes in the standard registration mode. The beginning of work was preceded by calibrations of recorders and sensors of MT stations. At all observation points, a control recording of at least 40 minutes was preceded by a check recording to assess the level of interference and adjust the parameters of the working recording. The electric components of MT field were measured using measuring units with electric dipoles 50 m long. The magnetic field components were measured using MTS-50 induction sensors. At all sounding points, grounding of dipoles was performed using non-polarizing electrodes, at 9 observation points including the DMTS point, grounding of dipoles was performed according to the "sensor to sensor" principle with the previous observations conducted in 2020. The orientations of measuring units at these points completely repeated the previous deployments. Installation of eight new MTS points was carried out between the observation points previously worked out in 2020, ensuring an equal distance to neighboring points, taking into account the terrain relief.

Team №4 carried out work on the Boom profile using electrotomography and induced polarization methods using the Skala 48 multielectrode station. Registration of data on the profile was performed by two types of unit: "Schlumberger" and "Wenner". Operation of the station was performed using two multielectrode cables, the length of each connecting cable is 120 meters, installation of electrodes was carried out with a step of 5 meters, the total number of electrodes when deploying two connecting cables is 48 pieces. The length of the work area was 3555 meters, registration was carried out in 29 basic observation points. Upon completion of the main works on the profile, in the area of points FT9 (DMTS) - FT8 (MTS), a trial 24-hour monitoring was carried out in number of 36 registrations, duration of each 42-44 minutes by electrotomography and induced polarization methods, Schlumberger installation type.
