Impact of Seismic and Air-Blast Waves Caused by Civilian and Military Explosions on Critical Infrastructure Facilities

The parameters of seismic waves during a civilian explosion in the directed destruction of brick chimneys by detonation of explosive charges were determined using a seismic measuring complex consisting of standard onecomponent sensors (SM-3) for recording the parameters of vertical, longitudinal, tansverse (vert (Z), long (X) and tran (Y)) components of the oscillations, the electrical signals from which are transmitted to a personal computer (PC) through a 16-channel analogue-to-digital converter (ADC). Similarly the parameters of seismic and acoustic waves from a military explosion during the impact of shells on the Kyiv TV tower were determined using a MiniMatePlus seismic station (Canada), consisting of a MiniMatePlus seismograph, a 3-component sensor for recording the parameters of vertical, longitudinal, tansverse (vert (Z), long (X) and tran (Y)) components of the oscillations (seismic) and a microphone for measuring the air-blast waves (acoustic). The results from both seismometric measurements of the parameters of earth surface vibrations during the collapse by blasting of a high-rise chimney (60 m) in the village of Kalynivka, Vasylkiv district, Kyiv region, and the results of seismic and acoustic vibrations during the explosion on 01 March, 2022, in Kyiv, and the missile strike on the Kyiv TV tower, with their subsequent destructive effects, both on the ground and in the air, are presented. A comparison of the parameters for a civilian and a military explosion, with the available calculation methods for determining the seismic and acoustic effects of these explosions, is presented.
