On this day in 2013 - February 15th - a meteor explosion occurred over Chelyabinsk in Russia causing around 1500 injuries.

The meteoroid was about 20 meters across with a mass of 12,000-13,000 metric tonnes. Fortunately, the explosion occurred high in the atmosphere and the atmosphere absorbed much of the energy. However the shock waves caused a lot of damage, and many of the injuries were from flying glass.
