Pray for an Asteroid

On the morning of February 15, 2013, a 500-ton meteor entered the atmosphere somewhere near the Ural mountains, in the vicinity of Chelyabinsk, Russia, an industrial city of over a million. The intensity of the blast was estimated at around 500 kilotons of TNT equivalent, or 30 nuclear bombs of the type the Americans dropped on Nagasaki, Japan. The shock waves from the sonic boom it created blew out numerous windows. Around a thousand people were wounded, mostly with lacerations from flying glass; 40 of them remain hospitalized. The damage is being estimated at over one billion rubles ($330 million USD). Over 24,000 workers and volunteers, coordinated by Russia's Emergency Ministry, went to work on the clean-up. Their specific emphasis was on keeping buildings from freezing (the temperature in Chelyabinsk is around -20ºC). By February 17 much of the damage had been repaired. Schools, hospitals and other pubic buildings had their windows replaced and were reopened. The government is supplying replacement windows to residential buildings.
