Abstract. The results of the study of seismic signals caused by the explosion of a February 15, 2013 meteorite are presented. The spectral and polarization analysis of the seismic waves are performed. The statistically optimal method of detecting a disorder of Gaussian autoregression processes (method c2) was used for the detection of weak signals from the meteorite explosion. Some features of the signals associated with an overground meteorite burst may permit the use of seismic data for monitoring future events.
Keywords: meteorite, seismic waves, spectrum, polarization.
