DEVELOPMENT OF RESEARCH ON FORECASTING STRONG EARTHQUAKES IN THE NORTHERN TIEN SHAN
Keywords:
telemetry network KNET, earthquake, seismicity, the Tien Shan Mountain system, epicenter mapAbstract
The Tien Shan Mountain system is one of the most earthquake-prone areas in the Central Asian region, where the maximum strength of earthquakes reaches 10-11 points. Within its boundaries, several zones of possible occurrence of earthquake sources with a magnitude of 7-8.5 are identified. The main seismogenic structures are the North Tien Shan, Gissar-Kakshaal (Southern Tien Shan) and Central Tien Shan seismically active zones. The article discusses the main stages in the development of prognostic research in the Northern Tien Shan. The local telemetry network KNET, installed here in 1991, allows you to register earthquakes in digital form, collect and process seismic information in real time. Note that KNET has no analogues in the Central Asian region. At the same time, geophysical, geodynamic, hydrogeochemical, hydrodynamic and other types of monitoring observations are carried out in order to identify precursor anomalies of expected strong earthquakes.
