Investigators are investigating the cause of a mysterious “sonic boom” that was heard by thousands of residents in Massachusetts and Rhode Island on Saturday afternoon.
Around 2 p.m. local time, residents across eastern Massachusetts, including the Boston metropolitan area, reported hearing a loud boom accompanied by shaking in homes and buildings. The sound was described as an explosion-like noise or sonic boom and was reported as far south as Rhode Island and in locations including Cambridge, Medford, Wellesley, Newton, Melrose, and areas near the South Shore.
Multiple residents contacted emergency services, leading to an influx of 911 calls. Boston Police Department officials dispatched officers to investigate, with initial focus on the Brighton area.
“I don’t know [what it is]. I’m getting tons of calls. It’s kind of bizarre,” a department spokesperson told the Daily Mail.
Dashcam and other video recordings captured the sound, with one resident in Cambridge noting a double bang and leaves on trees remaining still, consistent with a sonic boom rather than a ground-level event. Viewers reporting to local media outlets like WCVB described the experience, with one Melrose resident from Melrose stating that it shook “the whole house, actually all houses in the neighborhood,” and was “much louder than a transformer exploding and definitely not an earthquake.”
@MsCoffee76 I just got off the phone with Miss coffee and she said they heard a loud explosion in Massachusetts and also Rhode Island. It looks like it’s a trending topic here on X. Does anybody have any information on this topic? pic.twitter.com/QKNXcYFu7z

The U.S. Geological Survey (USGS) confirmed no seismic activity corresponding to the reports, ruling out an earthquake. No military exercises, aircraft incidents, or industrial explosions were immediately linked to the event either.
Meteorologists pointed to satellite data as a potential explanation. NOAA’s GOES-19 Geostationary Lightning Mapper (GLM) detected a distinct flash over the Massachusetts coast at approximately the same time, around 2:11 p.m.
Spaceflight meteorologist Nick Stewart noted on X that the flash density product showed an anomalous flash “pretty distinctive of a bolide/meteor reentry” east of Boston. “This is the likely source of the loud boom/explosion,” Stewart speculated.
WBZ-TV Chief Meteorologist Eric Fisher and others echoed this assessment, indicating the event was consistent with a meteor or bolide entering the atmosphere and producing a sonic boom upon fragmentation or deceleration.
Such events have occurred previously in the region and elsewhere, where large meteors (bolides) generate audible shockwaves that can be felt over wide areas without causing ground damage. No meteorite fragments or impact sites have been reported in this case.
The investigation remains active but preliminary, with officials continuing to gather reports and data. No further incidents were reported in the immediate aftermath.
