Hmmm, I think I'll wait for the above to be confirmed. That seems a bit large to me.
“But late Friday, NASA revised its estimates on the size and power of the devastating meteor explosion. The meteor’s size is now thought to be slightly larger about 55 feet (17 m) wide with the power of the blast estimate of about 500 kilotons, 30 kilotons higher than before, NASA officials said in a statement.”
“The meteor was also substantially more massive than thought as well. Initial estimated pegged the space rock’s mass at about 7,000 tons. Scientists at NASA’s Jet Propulsion Laboratory in Pasadena, Calif., now say the meteor weighed about 10,000 tons and was travelling 40,000 mph (64,373 km/h) when it exploded.”
There was another meteorite that hit Cuber!
February 16, 2013 - Another February 14th Meteor Report -
This One Over Cuba.
Before the big space rock exploded with the force of 300 TNT kilotons and crashed into central Russia at 9:20 PM local time on February 14 (3:20 AM GMT), another fireball was videotaped over Rodas near Cienfuegos, Cuba, around 8 PM local time (1 AM GMT), six thousand miles from the exploded meteor impact sites in Chelyabinsk east of the Ural Mountains. Rodos residents described a roaring sound in the sky and a moving bright light that exploded and shook some houses, but no damage or injuries were reported. Cuban media report that scientists are trying to find pieces of that explosion.
