- Abstract
This work determines the parameters of the meteoroid that exploded in Chelyabinsk oblast on February 15, 2013. Using video observation and automobile registration cameras, we identified the trajectory and velocity of the meteoric body from the beginning of its glow to the destruction. The precise explosion time (03:20:34UTC) was determined on the basis of records of the broadband seismic stations and arrivals of the surface wave. The estimated explosion energy with assumption of a point source similar to a high thermonuclear explosion was 100 kt in TNT equivalent based on the surface wave amplitude. The archive of records of seismic stations during the meteorite flight is composed.
