Just an interesting [update](http://www.bbc.co.uk/news/science-environment-23066055). Good thing that it exploded so high up (14.5 miles according to [Wikipedia](http://en.wikipedia.org/wiki/Chelyabinsk_meteor)). > [@](#): > > The shock wave from an asteroid that burned up over Russia in February was so powerful that it traveled twice around the globe, scientists say. > > They used a system of sensors set up to detect evidence of nuclear tests and said it was the most powerful event ever recorded by the network. > > More than 1,000 people were injured when a 17m, 10,000-tonne space rock burned up above Chelyabinsk. > > _\_ > > Alexis Le Pichon, from the Atomic Energy Commission in France and colleagues report that the explosive energy of the impact was equivalent to 460 kilotonnes of TNT. This makes it the most energetic event reported since the 1908 Tunguska meteor in Siberia. ---

Kilotons or kilotonnes? ---
