The Independent reports, the shockwave from a meteor which exploded over Russia earlier this year traveled twice around the earth, scientists have said.
More than 1,000 people were injured when the 10,000-tonne, 17m rock exploded over the town of Chelyabinsk.
Tremors from the explosion of the space rock were recorded at 20 'infrasonic' monitoring stations around the globe, says The Independent, recording seismic readings of potential nuclear explosions underground.
The explosion occurred on 15 February this year when the asteroid, which entered the Earth's atmosphere travelling at 50 times the speed of sound, notes The Independent, exploded in an air burst above the southern Ural region of Russia. Some 7,200 buildings in six different cities were damaged by the explosion.
