Meteor Russia (2013)

On 15 February 2013, a small asteroid entered Earth's atmosphere over Russia at about 09:20 local time with an estimated speed of 18 km/s (40,000 mph); The dazzling light of the meteor was bright enough to cast moving shadows during the morning daylight. The object exploded in an air burst over Chelyabinsk Oblast at a height of about 15 to 25 km with a bright flash and a powerful shock wave. About 1,500 people were injured, two seriously.
All of the injuries were due to indirect effects rather than the meteor itself, mainly from broken glass from windows that were blown in when the shock wave arrived, which came several minutes after the bright flash. Over 7,200 buildings in six cities across the region were reported to have been damaged by the explosion.
With an estimated initial mass of 11,000 tonnes, and measuring approximately 17 to 20 meters across, the Chelyabinsk meteor is the largest object to have entered Earth's atmosphere since the 1908 Tunguska event and the 1930 Brazilian event, and it is the only meteor known to have resulted in a large number of injuries.
