It exploded around 9:20 a.m. local Moscow time

A meteor exploded in the sky above Russia early Friday morning, shattering the glass of thousands of windows and leaving many citizens injured.

The meteor, estimated to be about 10 tons, entered the Earth's atmosphere traveling at 33,000 MPH and exploded around 9:20 a.m. local Moscow time. The explosion occurred over Russia's Urals region about 18-32 miles above the ground.

According to Chelyabinsk health chief Marina Moskvicheva, about 985 people in the city of Chelyabinsk alone required medical assistance. Approximately 110 of them have been hospitalized, and about 159 of the injured were children. This doesn't include other possibly injuries in other cities.

The Emergency Ministry said 20,000 rescue workers have been mobilized.

Vladimir Stepanov of the National Center for Emergency Situations at the Russian Interior Ministry said about 270 buildings have been damaged due to the explosion, where most of it consists of broken glass. Hospitals and schools are some of the buildings affected.

Another report from RT.com said 3,000 buildings alone were affected in Chelyabinsk, where shattered window glass measured 100,000 square meters.

The Russian space agency Roscosmos said that one meteroid entered the atmosphere and burned into meteorites that spread across three regions in Russia, including Chelyabinsk. Some were believed to be scattered in neighboring Kazakhstan as well.

After reading more about the meteor, I don't think your analysis is correct.

This explosion had 20-33 times the energy of the Little Boy dropped on Hiroshima (300-500 kilotons vs 15). According to estimates, the major exlposion/breakup occurred at an altitiude anywhere between 12 and 32 miles high (Nasa said 12-15, Russia said 19-32), compared to 1,968 ft at Hiroshima. At the low end of the estimate, that's 63,360 ft high -- 3,000 feet higher than the Concorde's maximum cruising altitude. At the high end of the esitmate, that's 168,960 ft -- the top edge of the stratosphere.

Had this thing broken up closer to earth, we could have seen some major damage.

Now if the articles I read are misinterpreting NASA's words and and the total energy of the object was 300-500 KT, then maybe I'm wrong.

Forgot the point: That kind of explosion is going to make one heck of a shockwave and sound.

What you're seeing is the media incorrectly reporting what they've heard scientists saying.

The figure they gave for the "explosion" is actually the figure for the kinetic energy of the meteor. Basically it's just mass x velocity. Since it obviously came to a stop it had to dissipate all that kinetic energy in the atmosphere. It doesn't mean that it exploded.
