Meteor Blast Over Bering Sea Was 10 Times Size of Hiroshima (theguardian.com)

A meteor explosion over the Bering Sea late last year unleashed 10 times as much energy as the atomic bomb that destroyed Hiroshima, scientists have revealed. From a report: The fireball tore across the sky off Russia's Kamchatka peninsula on 18 December and released energy equivalent to 173 kilotons of TNT. It was the largest air blast since another meteor hurtled into the atmosphere over Chelyabinsk, in Russia's south-west, six years ago, and the second largest in the past 30 years. Unlike the Chelyabinsk meteor, which was captured on CCTV, mobile phones and car dashboard cameras, the December arrival from outer space went largely unnoticed at the time because it exploded in such a remote location. Nasa received information about the blast from the US air force after military satellites detected visible and infrared light from the fireball in December.

Lindley Johnson, a planetary defense officer at Nasa, told BBC News that blasts of this size were expected only two or three times a century. The space agency's analysis shows that the meteor, probably a few metres wide, barrelled into Earth's atmosphere at 72,000mph and exploded at an altitude of 16 miles. The blast released about 40% of the energy of the meteor explosion over Chelyabinsk, according to Kelly Fast, Nasa's near-Earth objects observations programme manager, who spoke at the 50th Lunar and Planetary Science conference near Houston.

      I wonder how "random" (or more technically: uniform) the distribution really is though. Most meteors move within the ecliptic, and so will approach the Earth "from side" and not "from top" or "bottom". As such, at higher lattitudes a 1 square km of Earth's surface will probably have less chance of being randomly hit than 1 km sq close to the equator, because it is much more angled versus the path of average meteor's approach...
