Visit of RAS academicians to Research Station of RAS

   On October 31, 2024, the RAS leadership delegation visited the Research Station with a working visit. The delegation included Deputy President of the RAS - Academician of RAS Petr Aleksandrovich Chekmarev, Deputy Chairman of the National Committee of Geologists of Russia - Academician of RAS Alexander Olegovich Gliko and Chief Specialist of the Department of International Regional Programs and Projects of RAS - Inna Leonidovna Syrus. The heads of the Research Station laboratories acquainted the guests with the scientific directions of the laboratories and the results of their activities. During the excursion, the delegation got acquainted with the infrastructure, activiry, working conditions and features of conducting field experimental work in the mountainous conditions of the Tien Shan.

20th Anniversary of the CAIAG

  On October 8-9, 2024, the Anniversary Conference with international participation dedicated to the 20th anniversary of the Central Asian Institute of Applied Geosciences (CAIAG) on the topic "Past achievements and future challenges of applied geosciences in Central Asia" was held. The conference was held at the International University of Kyrgyzstan (Bishkek).

  The staff of the RAS took an active part throughout the entire duration of the conference in the section "Dangerous Natural Processes and Phenomena in Central Asia".

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).
