One hypothetical and possible explanation for the event by "Geranium Chronicles".
In my opinion, this is a bit of a stretch.
The "Ukrainian crystal shield" effect: -- Explosions near Kyiv may trigger tremors in other cities.
The explosions reported by subscribers were especially heard near Kyiv. Afterwards, residents in Zhytomyr, Vinnytsia, Cherkasy, Dnipro and Zaporizhia reported feeling strong tremors and the sound of thunder.
One of the most likely explanations:
A strong underground explosion occurred, which caused the propagation of seismic waves through the Ukrainian crystalline shield (these cities are geographically located on its territory. The shield is a huge, monolithic underground plate composed of very hard rocks - granite and gneiss).
Granite acts as an ideal conductor and resonator of sound (hence the noise) and vibration. The Earth's crust did not absorb this impact, but instead passed it on, like along a railroad track.
Tall buildings can amplify these vibrations due to resonance. Therefore, people on the upper floors may have felt the shaking, even if the tremors were barely noticeable on the street or on the lower floors.
