On February 15, 2013 the network of seismic and infrasound arrays of Kazakhstan recorded signals from fireball explosion around Chelyabinsk. Using infrasound station records the signals from fireball explosion were detected and investigated, apparent velocity, frequency bands, azimuths of signal arrival were determined. Using seismic stations data the time and place of acoustic wave ground impact and magnitude of seismic event were determined. This event is the second by its force after falling of Tungus meteorite in 1908.

The contribution of Kazakhstani stations has been suumarized in comparison with other stations of the International Monitoring System (IMS) in a number of associated phases into the REB bulletin (Reveiwed Events Bulletin) of the International Data Center (IDC). It has been demostrated that all stations of Kazakhstan, both seismic and infrasound ones, are quite effective in monitoring and take one of the first places. This is confirmed by the results of mapping of the epicenters of the events of the world as well as such parameters as minimum amplitude and proportion of a number of events detected with participation of Kazakhstani stations to the general number of events in REB. The region of Central Asia (CA) has been considered in detail in the REB results as well as bulletins of Kazakhstan National Data Center (KNDC) – seismic and infrasound – with examples of estimate of real-time accuracy of locations. Infrasound bulletin of events of KNDC on CA has been compared with REB. In KNDC bulletin the location has been implemented as per data of four infrasound stations, including one Russian station Zalesovo. A larger number of events has been noted in KNDC bulletin in comparison with the REB one.

The paper describes the results of studying the capacities of the new infrasound array Makanchi in recording infrasound signals from new sources that have not been studied earlier. The first results are presented for a cooperative data processing from the four arrays: Aktyubinsk IS31, Kurchatov, Russian station Zalesovo I46 and new infrasound array Makanchi.
