What was that boom? If you felt a thunderless bang, windows rattling, or a sudden pressure wave in 2019, you weren’t alone. Around the world, residents reported mystery booms and skyquakes—brief, explosive sounds with no obvious source. Many turned out to be meteors, military exercises, icequakes, or industrial incidents—but plenty remained unexplained.

Common causes of mystery booms

  • Meteor fireballs & sonic booms that crack loudly as shockwaves reach the ground.
  • Earthquakes & icequakes (frost quakes) that produce audible cracks and rumbles.
  • Military training & industrial events (detonations, plant incidents, demolition).
  • Atmospheric & coastal acoustics where surf or inversion layers carry sound unusually far.
