The Tunguska Event, or Tunguska explosion, was a powerful explosion that occurred near the Podkamennaya (Lower Stony) Tunguska River in what is now Krasnoyarsk Krai of Russia, at 0 hours 13 minutes 35 seconds Greenwich Mean Time (around 7:14 a.m. local time) on June 30, 1908 (June 17 in the Julian calendar, in use locally at the time).
Although the cause of the explosion is the subject of debate, it is commonly believed to have been caused by the air burst of a large meteoroid or comet fragment at an altitude of 5–10 kilometres (3.1–6.2 mi) above the Earth's surface.

The whole number of scholarly publications on the problem of the Tunguska explosion between 1908 and 2009 may be estimated as about 1000 (mainly in Russian). Many a scientist participated in Tunguska studies, the most well-known of them being Leonid Kulik, Evgeny Krinov, Kirill Florensky,...
