A massive boom was heard in the Pittsburgh area on New Year’s Day, leaving residents wondering what caused the noise and ground to shake.
According to the National Weather Service, the noise was believed to be caused by a meteor that exploded.

On Saturday, Allegheny County Officials tweeted that there had been calls to 911 about the disturbance.
Officials said they did not know what caused the incident but had confirmed there was no seismic activity and no thunder or lightning when the incident happened.
While officials with the county had no idea what caused the noise, the NWS said their data showed a flash in the area that was not lightning around 11:26 a.m.
However, they did not confirm for certain that it was a meteor causing the noise and ground to tremble, but they did say in a tweet that it was “the most likely explanation at this time.”
Jill Tarsi, 42, told TribLive that she was on her couch in Hampton when she felt her home shake as she heard the boom.
“It sounded like a house was exploding,” Tarasi told TribLive. “I have friends from all over saying they heard it, too.”
