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

10.09.2024

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.

The tests focused on the innovation in the equipment — enlarged 100*100 m probing frame, which allows expanding the range of controlled depths of the earth's crust. A series of tests were conducted in modes with a pseudonoise sequence of probing pulses and a number of probings with periodic sequences. A comparison of probing frames was conducted — 50 meter and 100 meter. The orientation of these frames to the cardinal points was preserved and repeated the previously conducted measurements at separate point.

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.

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".

News of 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.

RS RAS and IS NAS KR scientific collaboration 

June 11, 2021

    The cooperation between the RS RAS and the Institute of Seismology of the National Academy of Sciences of the Kyrgyz Republic (IS NAS KR) continues in the field of seismological research.

    The employees of the Institute of Seismology carried out field seismological research in the Issyk-Kul region in accordance with two agreements from January 8th to May 21t, 2021. The Group of New Technologies Introduction has prepared and delivered three sets of RT130-01 seismic stations with STS-2 seismic sensors. The software and methodological documents for conducting research were also handed over. RT130-01 stations and STS-2 seismic sensors were purchased with financial assistance of CRDF (U.S. Civilian Research and Development Foundation) - American Civilian Research and Development Foundation.

    Field works involves the installation of RT130-01 type seismic stations, complete with wide-range STS-2 seismic sensors in the studied area and continuous recording for a certain time of microseisms and vibrations from remote earthquakes and industrial explosions. The duration of observations depends on the level of seismic activity at the territory and is set in such a way as to register at least 10 seismic events with good recording quality. One recording point was taken as a reference. The rest of the items are mobile.

    Problems arose during the data processing. The level of seismic interference is significantly higher than the level of microseisms during the station installation and the terminal usage, with the help of which the equipment is controlled and monitored. Microseisms are indistinguishable in comparison with these background disturbances. It is necessary to remove noisy beginning and the end in the data record and areas with the operator presence near the sensor for high-quality data processing.

    The staffs of GNTI RS RAS also provide IS NAS KR with methodological assistance, operator training and consultations during field work, provision of seismic data processing programs.

    The maintenance of the network of GPS stations continues. You can see below the workplace at the Osh’s station in the picture:

    After 7 years of cooperation, our curator Sarah Doelger moved to another UNAVCO division. Jacob Sclar will temporarily perform her duties.

KNET и GPS geophysical nets operation

04th September 2020г.

  The scheduled works at KNET and GPS nets objects were made by the Group of New Technologies Introduction (GNTI) after the COVID quarantine cancellation.

  The top part of the KNET East Repeater mast was bended by strong wind. Fortunately the antennas were not damaged. 

  Two masts for antennas directed to the Chumysh Repeater, ULHL and KZA stations were installed to fix the problem. The solar panels were left on the old thick mast. The Institute for Seismology of the National Academy of science of Kyrgyzstan employee Tatjana Nikitenko assists to monitor the stations operation.

  The leading engineer S.M. Konovalov prepared new GPS server to swap the old one in communication chamber. Trips to update the TALA and SUMK GPS stations are scheduled in autumn time.

  The stations data download occurs in normal mode. Operators-colleagues perform the data transfer from 4 stations: KMTR (at Kumtor mining), KRTV (close to Kurchatov city in Kazakstan), SEL2 (close to Medeu skate ring), PODG (close to Podgornoe village 200 km away to East from Almaty). 4 stations data is downloading automatically through the phone and radio channels by GPS server. The GPS data quantity and quality are checked by special program and staff daily. 2 stations data (OSHK and KAZA) is download manually by NEI group staff. 

  Unfortunately it is impossible to reach the RS RAS objects in Kazakstan due to the quarantine. The important arrangements were performed by Chumysh Repeater guards. 

14^th October 2020.

The reliability increasing of the data download process was the purpose of visit to TALA (Talas city) GPS station on 22-24^th September. The second purpose was to decrease the expenses for data download through the intertoll trunk. Modernization arrangements were made by the Group of New Technologies Introduction (GNTI) leading engineer Sergey Konovalov.

The intertoll trunk communication channel troubles appeared periodically before of the old phone radio extender. The line of sight between RS RAS and 21t Phone Station disturbs some times.

The GSM 900/1800МГц cellular modem TELEOFIS RX100-R2В was bought in Moscow. The modem firmware was update after interaction with supplier. Many program changes were made in the GPS server located in the communication room. The data transfer testing was made at RS RAS. O! cellular provider is used. The modem and external antenna were installed at GPS station. The data download process through cellular network starts by GPS server at first. The cellular data transfer is cheaper as intertoll trunk transfer. The intertoll trunk transfer start at second time if all the data was not download. The data residual downloads in this case.

The expenses will be decrease in terms of numbers about 9-11 times after some week’s usage experience. Expected month’s costs are 300 soms. 3500 soms are the costs for the month’s intertoll trunk usage.

6 Sonnenschein А600 batteries (500Ah, 2V, 1998 year production, 22 years usage) were change by one gel 100Ah battery manufactured in Saint Petersburg. 22 years usage is a perfect parameter for the Sonnenschein gel batteries.
