Paper Abstract

The effect of infrasonic pulsed radiation from the Chelyabinsk bolide on the perturbations of the electron concentration in the D region of the Earth's ionosphere is considered. According to the electromagnetic measurements in the geophysical observatory Mikhnevo of the Institute of Geospheres Dynamics of Russian Academy of Science (IDG RAS), an estimate of the displacement of the reflection point of the SDV signals is obtained. Influence of infrasound radiation on the propagation of VLF signals on the Novosibirsk-Mikhnevo path is considered. The amplitude of the displacement of particles of the environment from infrasonic radiation is estimated. There is a good agreement between theoretical and experimental estimates.
