Geology in the News - Russian Meteorite Impact

A meteorite impacted in Chelyabinsk, Russia today (9:20 am local time) and caused massive damage via sonic booms shattering windows. This left about 1,000 people injured. Below are some of the videos and news reports on the topic. The meteor was about 10 tons as it entered the atmosphere and was traveling between 33,000-45,000 mph. Most of the meteor was destroyed upon entering the atmosphere. It is estimated that 1-5% of the original mass have struck ground (in essence going from a meteor to a meteorite). This also has no correlation to the passing asteroid expected later today.



This is the only one I have found showing the sonic boom.
