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.
