Meteor Fragments Over Northeastern US, Producing Loud Sonic Boom

On May 30, 2025, at approximately 2:06 p.m. local time, a meteor entered Earth's atmosphere and fragmented over the northeastern United States, producing a loud sonic boom heard and felt across multiple states.

No injuries or property damage were reported. NASA confirmed the object was a natural meteor—not space debris, satellite re-entry, or an earthquake.

Event Details

The meteor fragmented at an altitude of approximately 40 miles (64 km) over northeastern Massachusetts and southeastern New Hampshire. NASA reports the object was traveling at roughly 75,000 mph (120,000 km/h) before breaking apart.

The American Meteor Society (AMS) estimated the meteor was 3 to 5 feet (1 to 1.6 meters) in diameter with a mass of up to 5.6 metric tons prior to fragmentation.

The energy released at breakup was equivalent to approximately 300 tons of TNT (with one source estimating 230 tons), producing a sonic boom that rattled windows and shook houses across the region.

Detection and Observations

Multiple agencies and instruments detected the event:

NOAA's GOES-19 satellite captured the flash via its Geostationary Lightning Mapper (GLM)
National Weather Service radar recorded signatures from Boston (KBOX), Boston Logan (TBOS), Long Island (KOKX), and Albany (KENX)
The United States Geological Survey (USGS) received shaking reports but confirmed no seismic event was recorded—indicating a sonic boom from a suspected bolide, not an earthquake
The American Meteor Society collected dozens of reports from Delaware to Montreal, including accounts of a double boom, ground shaking, and a daytime fireball
A dashboard camera in New York captured the event

Official Statements

Jennifer Dooren, NASA deputy news chief, stated the fireball was not associated with any active meteor shower—a natural object, not space debris or a satellite.

NASA's Astromaterials Research & Exploration Science division reported that remnants fell into Cape Cod Bay at a depth of 34 meters (100 feet), adding that the meteorites are within reach from a boat using a 100-foot rope.

"The meteor was definitely bigger than a normal fireball, about a yard wide."
— Robert Lunsford, American Meteor Society

The Massachusetts Executive Office of Public Safety and Security confirmed receiving reports of an audible boom and ground tremors, with no emergency requests linked to the event. The Watertown Police Department reported numerous resident calls about a loud sound in eastern Massachusetts. The Massachusetts Emergency Management Agency also received reports of shaking.

Shauna Edson, an astronomy educator at the Smithsonian National Space and Air Museum, explained that the sound resulted from air compression as the meteor moved rapidly and from the stone breaking apart under stress. She noted that analysis of the meteor's brightness, speed, angle, and duration helps determine its origin—possibly a fragment of an asteroid or other small space object.

Robert Lunsford of the American Meteor Society noted it was unlikely the meteor struck the ground; if it did not burn up completely, it would have landed in the ocean.

Meteor Characteristics

NASA's analysis revealed several unusual features:

The meteor entered at an unusually steep angle
It was detected at an altitude of 31 miles—double the typical detection altitude of 15 miles
Radar tracked the meteor for approximately 2 minutes, shorter than the usual 8–10 minutes
The density was calculated at 8,000 kg/m³, consistent with an iron meteorite
Data suggests the meteor broke into fragments and produced small pieces
NASA stated the meteorite was "evidently very mechanically strong"

Broader Context

Most meteors burn up harmlessly in the atmosphere. Larger objects can survive long enough to create fireballs and shock waves. NASA noted that such objects are difficult to track in space and generally pose no serious threat to populated areas.

By comparison, near-Earth asteroids larger than 460 feet (140 m) in diameter are more dangerous and easier to track. NASA monitors over 40,000 such large asteroids.

The only documented case of a person being directly hit by a meteorite occurred in 1954 in Sylacauga, Alabama, resulting in minor injuries. In 2013, a larger meteor exploded over Chelyabinsk, Russia, releasing energy equivalent to about 440,000 tons of TNT, causing injuries and property damage.

This event follows other recent meteor sightings in 2025 and 2026, including:

A green fireball over Mount Mayon volcano in the Philippines (May 25)
A meteorite that struck a Texas home (March 21)
A fireball over Ohio (March)
A fireball over Texas that scattered meteorites

Additionally, a sonic boom event in South Carolina the previous day remained under investigation at the time of this report.
