An energy blast equivalent to 27 tons of TNT was created by a meteorite that exploded in the atmosphere over suburban Pittsburgh on New Year's Day.
NASA's Meteor Watch social media site said late Sunday a "reasonable assumption" of the speed of the meteorite would allow a "ballpark" estimate of its size as a yard in diameter with a mass close to half a ton.
It would have been easily visible in the daytime sky if the weather had not been cloudy.
As the meteorite broke apart, the blast wave from the station registered.
Shannon Hefferan of the National Weather Service told the Tribune-Review that there was a flash over Washington County. Officials believed it was a meteorite that fell through the atmosphere. Hefferan said there was a similar event in West Virginia.
Residents in South Hills and other areas heard a loud noise and felt their homes shake. There was no thunder or lightning in Allegheny County.
