Meteor Breaks Up Over Massachusetts Causing Sonic Boom and Tremors

A bright meteor, known as a fireball, fragmented over northeastern Massachusetts and southeastern New Hampshire Saturday afternoon, producing a loud sonic boom and tremors felt across the region. NASA confirmed the event occurred around 2:06 p.m. Eastern Time, with the meteor breaking apart at an altitude of approximately 40 miles.

NASA estimated the energy released during the breakup to be equivalent to about 300 tons of TNT, which accounted for the loud noise and ground shaking reported by residents. The space agency described the object as a natural meteor, unrelated to any active meteor shower, space debris, or satellite re-entry.

The Massachusetts Emergency Management Agency received multiple reports of an audible boom and tremors in the eastern part of the state but noted there were no emergency police or fire requests linked to the incident. The United States Geological Survey (USGS) characterized the phenomenon as a “widely felt sonic boom from a suspected bolide,” explaining that unlike earthquakes, which occur at discrete locations, sonic booms happen along a linear path in the atmosphere. The USGS confirmed there was no earthquake or ground impact associated with the event.

Dozens of eyewitnesses across the Northeast reported seeing the fireball, helping scientists reconstruct its path through the atmosphere. Satellite lightning data from the National Oceanic and Atmospheric Administration (NOAA) showed a signature consistent with a meteor entering the atmosphere near the South Shore of Boston around the time the boom was heard.

Shauna Edson, an astronomy educator at the Smithsonian National Air and Space Museum, explained that meteors enter Earth’s atmosphere at incredible speeds, often between 25,000 and 160,000 miles per hour. Most meteors burn up harmlessly, but larger objects can survive longer, creating shock waves similar to those of supersonic jets. These pressure waves can reach the ground as sonic booms, sometimes heard dozens of miles away. Edson noted that the sound people hear is caused by air compression from the meteor’s rapid movement and sometimes from the meteor breaking apart.

Edson also said that if the meteor landed off the Massachusetts coast, it is unlikely any fragments would be recovered, as most meteorites fall into the ocean. However, eyewitness accounts and video footage can provide valuable information about the meteor’s brightness, speed, trajectory, and duration. She described meteors as “time capsules” that carry crucial information about the solar system.

This meteor event follows other notable fireball sightings and sonic booms reported across North America in 2026. Earlier this year, meteors exploded over Ohio and Texas, with the Texas event reportedly scattering meteorites across the Houston area, including an unconfirmed report of a fragment crashing through a home’s roof. Just a day before the Massachusetts event, residents in South Carolina reported a mysterious blast initially mistaken for an earthquake; the USGS later identified it as a sonic boom, though the exact source remains under investigation.

Researchers stress that there is no evidence these meteors pose an impact threat to Earth.
