:INFO The Tunguska Event On the morning of 30 June 1908, an enormous explosion tore across the sky above the Podkamennaya Tunguska River in remote Siberia. It flattened a vast stretch of forest yet left no crater. The site was so isolated that the first scientific expedition did not reach it until 1927, nearly twenty years later, which let speculation run for decades. :TIMELINE From blast to explanation A fireball as bright as the sun crosses the sky. A blast levels the forest for many miles. 1908-07-01 | Tremors and unusual bright night skies are recorded across Europe and Asia. 1927-05-01 | Leonid Kulik leads the first expedition to the site and finds trees flattened outward from a centre. 1930-01-01 | The absence of a crater fuels theories from comets to, much later, fringe claims. The Chelyabinsk meteor renews scientific urgency around the Tunguska consensus. :STATS :MAP 60.886,101.894,Podkamennaya Tunguska, Krasnoyarsk Krai, Siberia :NOTE.half It remains the largest impact event in recorded history. Had it struck a city rather than empty taiga, the toll would have been catastrophic. | :NOTE.half The remoteness and the missing crater fed decades of exotic claims. The evidence on the ground points to a natural air burst. :LINK https://www.google.com/search?q=Tunguska+Event+1908 Read more about the event
