Description


Tunguska event

The Tunguska event was an enormously powerful explosion that occurred near (and later struck) the Podkamennaya Tunguska River in what is now Krasnoyarsk Krai, Russia, at about 7:14 a.m. KRAT (0:14 UT) on June 30 [O.S. June 17], 1908.[2][3] The explosion, having the epicenter (60.886°N, 101.894°E), is believed to have been caused by the air burst of a large meteoroid or comet fragment at an altitude of 5–10 kilometres (3–6 mi) above the Earth's surface. Different studies have yielded widely varying estimates of the object's size, on the order of 100 metres (330 ft).[4] It is the largest impact event on or near Earth in recorded history.[5] The number of scholarly publications on the problem of the Tunguska explosion since 1908 may be estimated at about 1,000 (mainly in Russian). Many scientists have participated in Tunguska studies, the best-known of them being Leonid Kulik, Yevgeny Krinov, Kirill Florensky, Nikolai Vladimirovich Vasiliev, and Wilhelm Fast.[6]
