Tunguska event. Image 1 of 3. Computer artwork of the object that caused the Tunguska event in Siberia, Russia, forming a fireball and trail of smoke (lower left) as it moves through the Earth's atmosphere at tens of thousands of kilometres an hour. Lake Baikal is at lower left. North is at right. The Tunguska event was a massive explosion that took place at 0717 on 30 June 1908. The fireball was observed low in the sky, moving north-west. Expeditions to the area found immense damage, with over 3000 square kilometres of forest flattened. It is thought that the explosion was a meteorite or comet breaking up and exploding above the surface. For a sequence of the Tunguska event, see images R305/218-220.
