Authorities of the National Aeronautics and Space Administration (NASA) American revealed that a meteor caused sonic booms over the city of Pittsburgh, Pennsylvania, during the night of New Year.
The agency estimates that the explosion of the celestial body was equivalent to 30 tons of TNT, with a speed of 45,000 mph, according to the site Meteor Watch.
Furthermore, it was estimated that its size approached a meter in diameter, with a mass of about half a ton, about 454 kilos.
The phenomenon could not be clearly appreciated, because that night it was cloudy. But scientists claim that would have been easily visible in the daytime sky, with a brightness up to 100 times higher than that of the full moon.
As indicated Meteor watch, the explosion was detected by infrasound station close to the fact, which recorded the shock wave of the meteor breaking.
In addition, professionals from the National Metereological Service revealed that the satellites registered a flash over county Washington shortly before 11:30 on Saturday.
Meanwhile, residents of nearby areas indicated having heard a loud noise and perceived movements and tremors in their homes, despite the fact that local authorities indicated that there was no seismic activity in the zone.
This would not be the first record of these characteristics, but rather a similar event occurred on September 17, in the county of Hardy, in West Virginia.
