Group of electromagnetic observations (GEO) news (Laboratory of Integrated Studies)

In August 2024, the staff of the Group of electromagnetic observations (GEO) of the Laboratory of Integrated Studies (LIS) resumed experimental work on the study of seismic and acoustic response of the geo-environment to sensing by electric pulses of the ERGU-600 electric exploration generator set. On August 12, 2024, measurements were made at the Southern Dipole field observation point by a mobile receiving station organized on the UAZ basis.

The registration of geoacoustic signal was carried out using the DYMAS-24 mobile digital system with a Veloget-3D triaxial geophone at the outcrops of bedrock near the feeding dipole. To view and analyze the measurements, a special data preprocessing program of the DYMAS-24 "EveProc" geoacoustic signal registration system was used, developed by LIS employees. Together with this, geomagnetic observations were carried out with the registration of the full vector of the magnetic field T, for which the MV-07 magnetic variation modular station was used.

The observations carried out by the laboratory make it possible to obtain additional qualitative information that can be used in the analysis of spatial and temporal features of deformation processes occurring within the polygon and its surroundings, as well as in the interpretation of data using other geophysical methods.

Regional GNSS measurements on the territory of Kyrgyzstan in 2024. KGS24a, KGS24b.

This year, the field group of the GPS Laboratory (LGPS) based on the Global Navigation Satellite Systems (GNSS) method conducts planned field measurements of GNSS network points on the territory of the Chui, Jalal-Abad, Talas, Issyk-Kul, Naryn regions of Kyrgyzstan within the framework of the State Assignment: "Study of modern movements of the earth's crust of the Tien Shan and adjacent territories by methods of ground and space geodesy" reg. No. 1021052806451-5-1.5.1.

Repeated surveys of the same GNSS points in the study area make it possible to determine the high-precision position of the point at the time of measurement and track the long-term rate of its displacement to solve fundamental geodynamic problems, as well as to assess the danger to the population and vital facilities. From May to September 2024, LGPS employees traditionally carry out two campaigns (KGS24a from 04.07.2024 to 03.08.2024; KGS24b from 21.08.2024 to 16.09.2024).

Each team includes an operator and a driver of a ZIL-131 or GAZ-33088 vehicle. Each team measures 14-15 points per month, with 36 hours allocated for each point. The vehicle mileage during one campaign was 1,500-2,200 km. The average vehicle mileage between observation points was 130 km. Since 2020, GSDN employees have been taking GNSS measurements using Russian-made MP-8 receivers capable of recording signals from 4 satellite constellations: GPS, GLONASS, Beidou and SBAS (Fig. 2).

News of the Laboratory of Advanced Hardware Development (LAHD)

On August 15, 2024, a series of experiments were conducted in the Chunkurchak gorge to test the technology of electromagnetic monitoring of the earth's crust stress-strain state using experimental electrical exploration measuring complex with pseudonoise signals developed at the Laboratory of Advanced Hardware Development (LAHD).

The main objective of the experiments is to test the sounding frame with a long side equal to 100 m introduced into the equipment. Previously, experiments were conducted with a frame with a long side equal to 50 m. Experiments were conducted with both a 50x50 frame and a 100x100 meter frame. The data obtained will allow a comparative assessment of the effectiveness (increase in depth) of probing with an increase in the area of ​ sounding frame.

News of the Group of New Technologies Introduction (GNTI)

On May 16-18, 2024, the GNTI employees upgraded the equipment of KAZA permanent GPS station, located near the Kazarman village. The LTE router was installed, which allows receiving data on a daily basis, as well as promptly monitoring the station operation. Earlier, data was delivered 8 times a year through a personal visit to the station, which led to high operating costs.

The KAZA station was launched in July 1997 in a joint project with NASA and is distinguished by high quality and stability of data.

GMTS News

In the period from July 16 to August 6, the MTS group consisting of 2 teams carried out work on the Ukok-2 profile, which is located south of the Kochkorka in the Kochkor district of the Naryn region. The works was carried out on magnetotelluric sounding (MTS) at 11 points. At 10 observation points, the duration of MT-field registration in the MTS mode was 36-43 hours, at the FT21 observation point in the DMTS mode, the registration was performed in the form of two registration sessions, the duration of each was about 240 hours.

The works was carried out using Phoenix MTU-5 measuring complexes in the standard recording mode. The start of the work was preceded by calibrations of the recorders and sensors of the MT stations. At all observation points, a control recording lasting at least 40 minutes was made to assess the level of interference and adjust the recording parameters of the working record.

The MT field electric components were measured using measuring installations with 50 m long electric dipoles. The magnetic field components were measured using MTS-50 induction sensors. At all sounding points, dipole grounding was performed using non-polarizing electrodes; dipole grounding was performed according to the “sensor to sensor” principle from previous years of observations. The orientations of the measuring installations at these points completely repeated the previous deployments.
