Researchers from the Urals Federal University, based in Yekaterinburg, have determined that the small stone-like pieces found near Lake Chebarkul in the Chelyabinsk region of Russia are pieces of space rock that landed there on Feb. 15.
A total of 53 pieces were brought to the university for analysis, the largest of which measured a centimetre in diameter, while the smallest was about one millimetre.
Researchers have determined that the composition of the stones is typical of meteorites — the product of a meteor, which appears as a streak of light in the Earth's atmosphere.
A circular hole can be seen in the ice of Chebarkul Lake where a meteor reportedly struck the lake near Chelyabinsk, about 1500 kilometres east of Moscow. (Associated Press) More than 1,000 people were injured last Friday after the meteor streaked across the sky and exploded over Russia's Ural Mountains with the power of an atomic bomb.
Amateur video taken by a local resident, Sergey Hametov, showed smoke trail hanging in the sky followed by a loud crash and alarms going off.
The video and information provided by Hametov were consistent with AP's own reporting of the event and with other videos depicting the same incident.
An interior ministry spokesman also said about 600 square metres of a roof at a zinc factory had collapsed.
There was no immediate clarification of whether the roof collapse was caused by meteorites or by a shock wave from one of the explosions.
Meteors typically cause sizeable sonic booms when they enter the atmosphere because they are travelling much faster than the speed of sound.
The meteor entered the Earth's atmosphere at a hypersonic speed of at least 54,000 km/h, the Russian Academy of Sciences said in a statement.
The astonishing Friday morning event blew out windows in more than 4,000 buildings in the region, mostly in the regional capital Chelyabinsk.
Russian police and officials were stationed at a frozen reservoir outside the town of Chebarkul on Saturday morning, the suspected landing site for meteorite fragments.
According to officials the fragments left an eight-metre crater in the ice.
Scores of people remain in hospital, but their injuries were reported not to be life-threatening.
Regional officials believe the damage from the explosion could cost as much as one billion rubles ($33 million Cdn) to repair.
