The POT surprised in the last when revealing that a meteorite caused sonic booms over the city of Pittsburgh, Pennsylvania, during the night in which it was celebrated New Year. According to the agency’s estimate, the explosion of the celestial body was equivalent to 30 tons of TNT.
The phenomenon was noticed by NASA’s Meteor Watch social media site, which, based on a “reasonable assumption,” indicated that the speed of the meteor was 45,000 mph (72,420 kph). Thus, he estimated its size roughly around one meter in diameter, with a mass close to the half ton (454 kilograms).
If it weren’t for the cloudy weather, the phenomenon would have been easily visible in the daytime sky, perhaps 100 times brighter than a full moon, NASA said.
Through a post on social networks, Meteor Watch reported that the detection of the phenomenon was possible thanks to a nearby infrasound station recorded the shock wave of the meteor when breaking, which allowed the estimations to be made.
The meteorologist of the National Meteorological Service, Shannon hefferanhe said to Tribune-Review that the data of the satellites registered a flash over Washington County shortly before 11:30 am Saturday and that authorities believed was due to a meteor “falling through the atmosphere.”
Hefferan said that a similar event occurred on September 17 in Hardy County, West Virginia.
In turn, according to the AP agency, South Hills residents and other nearby areas reported hearing a loud noise and that at the same they felt movements and tremors in their homes. Allegheny County authorities, however, confirmed that there was no seismic activity or any weather phenomenon that could explain it.
