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.
