The basic purpose of the project is to prolong operation of KNET on the present high level of quality and data availability (not less than 95 %), keeping up of existing pattern of service of the network and data transfer.
The Kyrgyz broadband seismological network (KNET) with a normal data return rate better than 95 % and ability to record remote seismic events with magnitude >3.5, is one of the most active world producers of seismological data for conducting modern seismological research. The seismograms are transmitted in near real time. They can be browsed through and are passed in 5-10 sec after the sensors have detected seismic event. KNET operatively ensures delivery of the high-performance seismic data to the scientist, which carry out seismological studies actually of all aspects, from monitoring domestic seismic activities and estimations of a seismic hazard up to detailed analyses of deep structure of Earth’s crust and mantle.
The data of the KNET network are used in Kyrgyzstan and Kazakhstan by national Institutes of seismology, National nuclear center of Kazakhstan together with laboratory LAMONT (USA) as well as institutes of the Russian Academy of Sciences. Thus the problems of the operating supervision behind seismic circumstances in locale, usage data of the KNET network for a service of the urgent dispatches, tracing behind variation of geodynamic circumstances in locale are solved with the purpose of an estimate of a seismic hazard, learning of a deep-seated structure of researched territory, monitoring of nuclear explosions over territories of China, Indium and Pakistan.
In a stage of organization to be making the uniform digital directory of Central Asia, which includes the data of seismic networks Kyrgystan, Kazakhstan, Uzbekistan, KNET. It is planned to prepare and to publish the integrated seismic bulletin of KNET and the seismic network of Kazakh National nuclear center. This will be the first step to the generalized digital directory for Central Asia seismicity. The Chinese scientists have exhibited interest in usage of KNET data, and also in association of a digital network located in territory the Tarim platform and KNET. However absence of enough good communication channels now restrains the decision of these problems.
The results of KNET operation are also being used in international scientific project to study if high-power pulses generated during start-up of geophysical magnetohydrodynamic machine (MHD-generator) and other high-power sources have influence on the regional seismicity.
