Disturbance of geophysical fields during explosion Tomsk bolide 16 October 2022

Abstract

Using the results of instrumental observations, acoustic, electrical and magnetic effects caused by the explosive destruction of a bolide on 10/16/2023 near Tomsk were established. It is shown that the effects have a non-local character and are recorded at a significant epicentral distance from the point of explosion of the bolide both during the event itself and during the arrival of the infrasound signal at the point of instrumental observations. Using an approach based on the properties of the infrasound signal not to change the characteristic frequency with distance, the energy of the source was estimated to be 3.7.1013 J.
