A loud explosion was reported in the southwest suburbs of Pittsburgh, Pa., on Saturday morning.

Allegheny County tweeted on Saturday morning that it received several 911 calls to say there had been tremor in the South Hills area.

Although there are theories, Allegheny County officials close to the N.Y.P. said the blast was not caused by an earthquake or lightning.

Residents in south-west Pennsylvania saw New Year’s Eve with a bang when many heard a loud bang and found their houses shaking at about 11.30am on Saturday morning.

Jill Tarasi, 42, said she was sitting on her couch in Hampton while the rise began.

The National Weather Service said the most probable but unconfirmed cause was an explosion of a meteorite.

Meteorologist Shannon Hefferan told the paper a similar bolt of lightning, believed to be a meteorite explosion, was registered in Hardy County, West Virginia, on September 17.
