  1. Managing Data from Seismic Networks & IRIS International Development Seismology September 9-15,2015, Hanoi, Vietnam Institute of Seismology, National Academy of Sciences, Kyrgyz Republic Kyrgyz System of Seismic Monitoring

  2. Institute of Seismology, National Academy of Sciences, Kyrgyz Republic Seismic monitoring Geographically Kyrgyzstan is located in the limits of the Tien-Shan orogen, the modern tectonic activity of which defines a high seismicity of this territory. Very strong earthquakes with magnitude up to 8 and a lot of weaker events occur here. In average we process about seven thousand earthquakes per year. That is why a seismic monitoring was and remains one of the most actual problems for our republic. Map of seismicity of Kyrgyz territory for 2014 (M ≥ 0.5, N=7931)

  3. Institute of Seismology, National Academy of Sciences, Kyrgyz Republic Developmental stages of Kyrgyz System of Seismic Monitoring • The instrumental seismic observations in Kyrgyzstan have begun since 1927 on the base of analogue stationsthat essentially influenced on the network efficiency. • In October, 1990 the first digital broad-band seismic station AAK10 has been installed on the Kyrgyz territory as observation point of Global Seismographic Network IRIS/IDA. This seismic station is included into IMS CTBTO as a 3C auxiliary stationAS060. • Since 1991 the telemetry network KNET consisting of 10 stations, equipped with broad-band high-sensitive devices has begun its operation here. • In 2007, within the frame of CTBT capacity building, NORSAR, with support from the Ministry of Foreign Affairs of Norway, provided the Kyrgyz Institute of Seismology with 10 digital broad-band stations, most of which have been installed in the south of Kyrgyzstan characterized by the high level of seismic activity. • In 2009 the new seismic network has been registered in FDSN as KRNET (Kyrgyz Republic Digital Network). At present it consists of 16 broad-band stations located on all territory of Kyrgyzstan. Moreover under IRIS support the real time data of 13 KRNET stations are openly accessible at the IRIS–DMC website. • Nowadays the Kyrgyz system of seismic monitoring includes 10 KNET stations and 16 KRNET stations, otherwise 26 seismic stations.

  11. Institute of Seismology, National Academy of Sciences, Kyrgyz Republic Data transmission and exchange • AAK (AS060) waveforms in real time mode are sending to the IDC CTBTO. • KRNET waveforms in real time mode are sending to the IRIS/DMC. • Since 2011 both preliminary and final bulletins of KRNET data are sending to the ISC. • Seismic bulletins  Xinjiang Uyghur Autonomous Region Earthquake Administration (China), Seismological Expedition of Kazakhstan, Institute of seismology of Uzbekistan, Geophysical Service of Russian Academy of sciences. • Seismic catalogue and waveforms under corresponding request  KNDC (Kazakhstan), NORSAR (Norway), GFZ (Germany), Institute of seismology of Tajikistan, Institute of seismology of Uzbekistan.

  12. Institute of Seismology, National Academy of Sciences, Kyrgyz Republic Database of Kyrgyz Institute of seismology • Seismic catalogue since 250 BC till present time. It contains information about 138000 earthquakes. • Seismic bulletins since 1950. • Archive of analogue seismograms both of earthquakes and different type of explosions since 1927. Archive of scanned seismograms of nuclear explosions (some part of them were digitized). • Catalogue of chemical explosions since 1990 till present time. • Catalogue of geomagnetic data since 1989 till present time. • Catalogue of geochemical data since 1988 till present time. • Catalogue of microshocks since 1987 till present time. • Catalogue of focal plane solutions since 1946 till present time. • Catalogue of tilting and strain data since 1986 till 2003.
