Kyrgyz Seismic Network KNET: Application of KNET Data in Scientific Researches - fig. 1

Kyrgyz Seismic Network KNET: Application of KNET Data in Scientific Researches - fig. 1 Seismic data from KNET are widely used by researches from many countries. Research branches include the following topics:
<br /><br />
• seismic velocity distribution and structure of Tien Shan and Central Asia;
<br /><br />
• calibrated records for the study of seismic wave propagation;
<br /><br />
• studies related to monitoring of nuclear explosions and their detection threshold;
<br /><br />
• study of deep structures of the Earth,
<br /><br />
• investigation of focal mechanisms and seismotectonic strains and many others.
<br /><br />
KNET data are used by the national Institutes of Seismology of Kyrgyzstan and Kazakhstan, National Nuclear Center of Kazakhstan, Research Station of the Russian Academy of Sciences and different emergency departments. In recent years, different institutes of the Russian Academy of Sciences have started to use KNET data in their research. The following tasks are now being solved: on-line monitoring of regional seismic conditions, application of KNET data for routine report services, tracking of changes in regional geodynamic conditions for seismic risk assessment, studies of deep structures of investigated areas. The National Nuclear Center of Kazakhstan together with the Lamont laboratory (USA) uses KNET data to conduct verification research. Due to the convenient territorial location of KNET, the Center monitors nuclear explosions in China, India and Pakistan. In progress is the creation of a united digital catalogue of Central Asia that would include data from seismic networks of KNET, Kyrgyzstan, Kazakhstan and Uzbekistan. KNET data attracts the interest of scientists from China. They are interested in integration of KNET and digital networks located in the Tarim Platform. Due to the absence of good communication channels, at present these tasks remain unsolved. KNET data are also used during interpretation of results of electromagnetic monitoring, measurements of earth surface movements by the method of space geodesy, and analysis of geoelectric structure based on magnetotelluric sounding in relevance to problems of modern geodynamics.
<br /><br />
There are enormous lists of publications based on KNET results (Appendix to reports on KNET exploitation, 2002, 2003, etc.), including three PhD theses:
<br /><br />
1. Robert John Mellors (University of California, USA, 1995) – “Two studies in Central Asian seismology: a teleseismic study of the Pamir/Hindu Kush seismic zone and analysis of data from the Kyrgyzstan broadband seismic network.”
<br /><br />
2. Albina Adamova (Institute of Seismology, NAS KR, 2004) – “Three-dimensional velocity model of Tien Shan earth’s crust by seismotomographic studies.”
<br /><br />
3. N.A.Sycheva (Research Station RAS, 2005) – “Studies of focal focus mechanisms and seismotectonic deformations of the Northern Tien Shan by the data from digital seismic network KNET.”
