What Caused the Boom

A bolide is a bright meteor or fireball that can break apart or explode in the atmosphere. NASA and the American Meteor Society confirmed the May 30 event was a natural meteor (bolide), not a satellite or space debris.

According to NASA, the meteor was traveling at about 75,000 mph and likely fragmented about 40 miles above the ground. When a bolide breaks apart, people on the ground may hear a boom, rumble, or explosion-like sound known as a sonic boom. The sound can arrive after any visual flash because light travels faster than sound.

The double boom reported across multiple states is consistent with a larger meteoroid entering the atmosphere and breaking into pieces at high altitude.

Was It an Explosion or Earthquake?

Based on reports, the boom was not linked to a confirmed local explosion. There were no reports of structural damage or industrial incidents tied to the sound.

WBUR reported that USGS did not detect an earthquake at the time of the reports, making a seismic cause unlikely.

NASA and the American Meteor Society later confirmed the cause was a meteor. However, people should still treat any visible fire, smoke, damage, gas smell, or injury as an emergency and contact authorities immediately.
