Tunguska event

1908 air burst explosion in Siberia, Russia

The Tunguska event was the explosion of between 3 and 50 megatons TNT equivalent in the Russian Empire's Yeniseysk Governorate, near the Podkamennaya Tunguska River in modern Krasnoyarsk Krai, on the morning of 30 June [O.S. 17 June] 1908. It was the largest impact event on Earth in recorded history (though much larger impacts occurred in prehistoric times, including the Chicxulub impact which ended the Cretaceous period). The event is attributed to a meteor air burst, the atmospheric explosion of a stony asteroid about 50–60 m (160–200 ft) wide.
