The explosion of an ammunition depot near Khmelnytsky is visible at seismic stations in Europe

Seismic and acoustic waves from this event are seen at European stations. It was big: ML~2.5-3.0. It is difficult to accurately calculate the TNT equivalent but for surface explosions, it should be between 10 and 100 t. Considering the fact it was not a concentrated source the upper limit is more probable. Actually, there were several distinct events close in space and detected within a few hours. The depot was likely not so simple. There was another event a few hours later with a larger magnitude to the south – likely underground, as no acoustic was observed.
