Russian meteor exploded with force of 30 Hiroshima bombs
The 55-foot rock, said by Nasa to have a mass of 10,000 tonnes, plunged to Earth in the Urals region on Friday morning, causing shockwaves that injured 1,200 people and damaged thousands of homes in an event unprecedented in modern times.
Nasa estimated that the energy released by the meteor’s impact with the atmosphere was 500 kilotonnes, around 30 times the force of the nuclear bomb dropped on Hiroshima in 1945. It entered the atmosphere and broke up at an altitude of around 32 miles, causing a shockwave that blew out windows and set of car alarms in Chelyabinsk two and a half minutes later.
