Meteor Over Massachusetts Triggers Explosion Reports in US
A meteor approximately 3 feet (nearly 1 meter) wide streaked across the northeastern United States on Saturday afternoon, generating a double sonic boom that prompted hundreds of emergency calls from residents across multiple states. The fireball, which entered Earth’s atmosphere near the Massachusetts-New Hampshire border at roughly 2:06 p.m. EDT, was visible from Delaware to Montreal, according to the American Meteor Society.
A Loud and Unexpected Afternoon
Reports of an explosion-like sound flooded police dispatches and social media shortly after the event. The Watertown Police Department in Massachusetts confirmed they were “getting numerous reports from residents of hearing a loud boom sound” and that it “was heard over the eastern part of the state.” The Massachusetts Emergency Management Agency (MEMA) issued a statement, as reported by GBH News, saying there were “no known emergency police or fire requests connected to these reports” and that officials did “not believe that there is any public safety threat.”
Many residents initially speculated about the cause — ranging from earthquakes to industrial accidents — before authorities and scientists identified the source. The U.S. Geological Survey confirmed that no earthquake had been detected, and that the shaking reported by residents was caused by the meteor’s sonic boom, not seismic activity, as USA Today reported.
NASA Confirms Natural Fireball
NASA officials confirmed later Saturday evening that the event was caused by a natural meteor — not space debris or a satellite re-entry. NASA spokesperson Allard Beutel said the meteor “appears to have fragmented at an altitude of 40 miles over northeast Massachusetts and southeast New Hampshire” while traveling at approximately 75,000 mph (120,700 km/h). The agency estimated the energy released at breakup was equivalent to about 300 tons of TNT, which accounted for the loud booms heard across the region.
Jennifer Dooren, NASA deputy news chief, told The Guardian that “this fireball was not associated with any currently active meteor shower, but it was a natural object and not a re-entry of space debris or a satellite.”
Meteor Experts Weigh In
Robert Lunsford, program monitor for the American Meteor Society, said the group received dozens of reports from Delaware to Montreal. “It was definitely bigger than a normal fireball, about a yard wide,” Lunsford told the Associated Press. He noted that while the meteor likely did not reach the ground, more trajectory data would be needed for a definitive conclusion. If any fragments survived atmospheric entry, they would have landed in the Atlantic Ocean off Cape Cod Bay.
Meteorologists also played a key role in identifying the event. Pete Bouchard, chief meteorologist at NBC10 Boston, identified the source as a “bolide meteor” using satellite data, while Nick Stewart, a spaceflight meteorologist, spotted an anomalous flash on NOAA’s GOES-19 Geostationary Lightning Mapper (GLM) satellite — a tool designed to detect lightning that can also pick up the distinctive signature of a meteor breaking up in the atmosphere.
What Made This Meteor Significant
At roughly 3 feet in diameter, this meteor was larger than typical fireballs, which are often caused by pebble-sized meteoroids. The energy release of 300 tons of TNT places it in the category of significant atmospheric meteor events, though it remains far smaller than major events like the 2013 Chelyabinsk meteor, which released approximately 500 kilotons of energy.
The event comes amid a period of heightened fireball activity in the United States. In April 2026, a fireball was spotted streaking over 100 miles across the eastern U.S., visible in multiple states including Connecticut, Delaware, New Jersey, New York, and Pennsylvania. March 2026 also saw numerous fireball sightings reported across the country.
No Injuries, No Damage
Authorities confirmed that no injuries or property damage have been reported in connection with the event. The meteor’s fragmentation high in the atmosphere — approximately 40 miles above the ground — ensured that the primary effects were limited to the loud sonic boom and a bright daytime fireball visible to thousands of witnesses across the Northeast.
What’s Next
Scientists at NASA and the American Meteor Society continue to analyze trajectory data to determine the meteor’s origin and whether any fragments may have reached the ocean surface. The event serves as a reminder of the constant, often unnoticed rain of natural space debris that enters Earth’s atmosphere daily, with most objects burning up harmlessly before reaching the ground.
