KYRGYZ SEISMIC NETWORK KNET

The Research Station (RAS) Kyrgyz Seismic Network (KNET) was established in 1991 with 10 stations equipped with STS2 seismometers. Real-time processing began in July 1998. KNET's catalog of earthquakes from 1994 to 2006, using programs like HYPOCENTER and 6-layer velocity models, boasts an impressive RMS of 0.2-0.3 sec. With over 5000 events recorded, KNET is utilized by scientific organizations like the Institute of Seismology and the National Academy of Sciences. Research subjects include nuclear explosion detection, deep Earth structures, seismic wave velocities, and focal mechanisms. KNET's data are instrumental in studying seismic activity distribution, while also facilitating international collaborations. For more information, reach out to nelya@gdirc.ru or visit gdirc.ru.

  3. KNET Location Year of creation: 1991 Number of stations: 10 Seismometers: STS2 (Streckeisen)

  4. KNET List of stations

  5. KNET Station, characteristics of STS2 sensor

  6. KNET Realtime Realtime process: July 1998 года Points: KIS,RS RAS,IRIS Programs: ANTELOPE -to be updated Operation system: SOLARIS 2.9

  7. KNET Catalog of earthquakes (1994-2006) Programm: HYPOCENTER 6-layer velocity model (Stive Roecker) RMS: 0.2-0.3 sec (1200 м) Number of events: more 5000

  8. KNET Using KNET data in Scientific Research Scientifics organizations Institute of Seismology, National Academy of Sciences of the Kyrgyz Republic; Institute of Physics and Mechanics of Rocks, National Academy of Sciences of the Kyrgyz Republic; Institute of Seismology, Ministry of Education and Science, Republic Kazakhstan; Schmidt Institute of the Physics of the Earth, Russian Academy of Sciences; Indiana University (US); Institute of Geophysics and Planetary Physics, University of California, San Diego (US); Massachsetts Institute of Technology (US); International Seismological Center (Thatcham, UK) Subjects of researchs The research connected with an opportunity of the control of nuclear explosions and studying of a threshold of their detection. Researches of deep structures of the Earth. Distribution of seismic waves velocities and velocity structures of the Crust of Central Asia. Studying of focal mechanisms and seismotectonics deformations and etc. Wide band seismological studies (grading records for studying distribution of seismic waves, spectra of seismic signals etc). Relationships between regional and global seismicity, and between weak and strong events occurring.

  9. KNET Using data for researchs in RS RAS Study of STD Distribution of omega angle ( stressed-strained state angle) Two regimes of STD: Strike slip and Ttanspression Study of distribution of seismic activity Distribution of seismisity: real, Puasson, Poya, Gamma.

  10. Resume • Digital seismic network KNET is a good tool for • World geoscience community • Regional (Central Asia) seismologists and geophysisists. • KNET is relevant for international collaboration under FDSN
