Did you hear that? Here’s what we know about the big buzz heard about MAS.

Local News “The Bolide meteor made a loud bang.”

Was it thunder? earthquake? meteor? Sonic boom?

People across Greater Boston and beyond heard and felt a loud bang Saturday afternoon, as reported across various social media platforms and neighborhood groups.

“Did anyone hear the loud explosion around 2:10pm in the Oak Square area?” Boston City Council President Liz Brydon posted in the Allston-Brighton Facebook group.

Some social media users speculated it was an explosion, earthquake or sonic boom.

Meteorologists quickly ruled out an earthquake and suggested that the incident was probably a meteorite. Here’s what local officials and meteorologists say:

“A very large flash detected by the GOES-19 GLM is not associated with active thunderstorms,” spaceflight meteorologist Nick Stewart reported.

“There is no lightning in this current storm, and there is no USGS earthquake,” NBC10 Boston meteorologist Pamela Gardner said.

I think this NOAA product that measures some sort of energy definitely shows the explosion in the atmosphere over Cape Cod Bay. This is what we all heard. Just a little bigger than the tree I thought it fell. #Boom pic.twitter.com/Gz0aPFEI4N

All – Numerous reports of a “big boom” with shaking felt at ground level across the inland mass from about Franklin Massachusetts northward into north central RI.

This afternoon, Massachusetts Public Safety officials received reports of audible booms and earthquakes in eastern Massachusetts. Although we don’t know the cause yet, there are no known emergency police or fire calls associated with these reports and we don’t believe…

– Executive Office of Public Safety and Security (EOPSS) May 30, 2026

“There have been hundreds of emergency calls across eastern MA, southern NH. and northern CT,” Northeast Massachusetts Emergency Alerts posted on Facebook at 2:31 p.m., confirming a loud sound was heard in the Peabody/Middleton/Linfield area.

“There is no confirmation of what this may have been, but there was no evidence of any type of fire or explosion when companies responded to investigate in several towns,” the post noted. “It’s possible there was an earthquake or some type of sonic boom. A similar incident occurred over the past few days in South Carolina. There have been no reports of any ongoing danger to the public.”
