Tunguska (ТунгуÑ?ка) is a remote region in Siberia, Russia. Now known as Evenkia, the area is largely uninhabited, but still reknown for the mysterious explosion that occurred there in 1908, near the Stony (Podkamennaya) Tunguska River.

Little is acutally known about what has been come to be called the Tunguska Blast or Tunguska Event. What is known is that on June 30, 1908, strange lights were seen in the sky early in the morning. At 7:17 a.m., a massive mid-air explosion (estimated to be between 10 and 15 megatons in strength) occurred. Somewhere in the region of 60 million trees across 2,150 square kilometers were destroyed, and an entire lake was vaporized. Amazingly, no one was killed.

The most common hypothesis to explain this blast is a very large meteorite. However, many details remain anomalous to meteorite impact.
