Kyrgyz Seismic Network Kyrgyz Seismic Network Kyrgyz Seismic Network. The territory of Kyrgyzstan is characterized by high seismicity. About three thousand earthquakes occur on average each year with magnitude up to eight points. Therefore, seismic monitoring is of crucial importance to the country. The Kyrgyz Seismic Network, KNET, is the first regional continuous telemetric network of very broadband seismic data in Kyrgyzstan. This network was jointly developed by several institutions under Joint Seismic Program by Incorporated Research Institutions for Seismology (IRIS), which were: University of California, San Diego, the Kyrgyz Institute of Seismology, and the Russian Institute of High Temperature Physics. As a
Seismic tomography frame to compare tomographic models to for iteration. Initial models had resolution of ~3000 to 5000 km, as compared to the few hundred kilometer resolution of current models. Seismic tomographic models improve with advancements in computing and expansion of seismic networks. Recent models of global body waves used over 10 traveltimes to model 10 to 10 unknowns. Seismic tomography uses seismic records to create 2D and 3D images of subsurface anomalies by solving large inverse problems such that generate models consistent with observed data. Various methods are used to resolve anomalies in the crust and lithosphere, shallow mantle, whole mantle,
