Parameters of infrasonic waves generated by the Chelyabinsk meteoroid on February 15, 2013

Resumo

Data from infrasound stations are used to determine the basic parameters of infrasonic waves generated during the passage and airburst of the Chelyabinsk space body: time lag, duration, spectral structure, dispersion dependence, and celerity. A simulation is performed for the parameters of the infrasonic waves. A comparison between the simulation and observation results shows a good agreement.
