Australian astronomer Brad Tucker has also pointed out that a brief magnitude 6.8 earthquake in the remote settlement of Syagannakh in Russia's Yakutia Republic was close to the right time to have been associated with the meteorite. A seismic plot shows a "short, sharp shock" that might have been some of the space rock exploding in the air, although Tucker acknowledges it could also be a coincidence.

Editor's Note: NASA has revised their size and energy estimates for the Russia meteor upon review of further data. Scientists now believe the small asteroid was about 17 meters, or 55 feet, in diameter and had a mass of 10,000 tons. The revised estimate of energy unleashed by the meteor is about 500 kilotons, more than 30 times the blast yield of the atomic bomb dropped on Hiroshima.


Only 55 feet and it did all of that? We got lucky this time.

Wow. This rock was on the threshold. Had it been any bigger...


Then something like this would have happened.

Russian scientists have recovered a giant chunk of the Chelyabinsk meteorite from the bottom of the lake it crashed into.

The meteor that blazed across southern Urals in February was the largest recorded strike in more than a century. More than 1,600 people were injured by the shock wave from the explosion as it hit near the city of Chelyabinsk, estimated to be as strong as 20 Hiroshima atomic bombs.

Scientists on Wednesday recovered what could be the largest part of the meteorite from Chebarkul Lake outside the city. They weighed it using a giant steelyard balance, which displayed 570 kilograms (1,256 pounds) before breaking.

Sergei Zamozdra, an associate professor at Chelyabinsk State University, told Russian television the excavated fragment was definitely a chunk of the meteorite.
