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
Passive seismic have been also applied in another planets. For instance, during Apollo missions, the Passive Seismic Experiment sensors were deployed that detected lunar "moonquakes" and provided information about the internal structure of the Moon. Passive seismic is much less expensive than well drilling. It is also cheaper and more environmentally friendly than active seismic, which requires a strong source of the seismic waves (like an underground explosion) to predict the structure. In some cases it may be the only method for which land access is granted by the land owner. Despite the method having been successfully applied in many parts of
