Witnesses saw a “blue-ish light, nearly as bright as the Sun, moving across the sky.” What followed was an estimated 15 megaton explosion which knocked over about 80 million trees in about a 1300 square mile area, forming a butterfly shape pattern. This also sent a shock wave throughout parts of Europe and Asia, registering as far away as England (about 4000 miles away). Further, the atmospheric pressure change was also significant enough to be measured all the way in Great Britain. Another interesting side effect of this blast was that, for several days after the blast throughout most of Asia and Europe, the night sky glowed. It was so bright that people as far away as China reportedly were able to read in the middle of the night by nothing but the glow of the sky.
