Propaganda and misinformation cannot fool seismographs. Designed to detect earthquakes, these devices capture any disturbance in the earth, be it a volcanic eruption, mining prospecting, a win for Barça, a hole in a quarry and, now, the bombs and missiles that fall on Ukraine. In a novel work published in the prestigious magazine Nature, a group of researchers demonstrates how a seismological network designed to detect nuclear tests thousands of kilometers away captures the explosions of the Ukrainian war. And there are many more than those recognized by both sides.
