	Tunguska event - Wikipedia, the free encyclopedia
		The curious effect of the Tunguska explosion on the trees near ground zero has been observed during atmospheric nuclear tests in the 1950s and 1960s, and is due to the shock wave produced by such large explosions.
		In 1965, Cowan, Atluri, and Libby suggested that the Tunguska event was caused by the annihilation of a chunk of antimatter falling from space.
		In a two-episode story arc of "The X-Files" ("Tunguska" and "Terma"), the Tunguska incident was purported to be caused by an asteroid impact.

		Tunguska (Тунгуска) is a remote, largely uninhabited region in Siberia, Russia.
		It is known for an enormous impact event near the Stony (Podkamennaya) Tunguska River at about 7:17 AM local time, on the morning of June 30, 1908, which felled an estimated 60 million trees over 2,150 square kilometres but did not leave a crater.
		The size of the blast is said to have been the equivalent of between 10 and 15 megatons of TNT (40 to 60 petajoules).

	Explosion Occurred in Stony Tunguska Region
		Tunguska is located in the Central Siberian Plateau, a sparsely populated, desolate region of peat bogs and pine forests.
		Tunguska is also NNE of the mysterious Lake Baikal (which curves down toward Irkutsk).
		The comparative isolation of the Tunguska region is perhaps best illustrated by the fact that Kansk, one of the main railroad towns nearest the explosion, is 2,500 miles from Moscow and 3,000 from St. Petersburg -- a distance as great as from New York City to Los Angeles.

	Tunguska phenomenon
		The possibility that the Tunguska event could be explained by the collision of an antimatter meteorite was put forward in 1965 by by Clyde Cowan, C. Atluri, and Willard Libby [5], and supported by Gentry [8] in 1966.
		A possible explanation for the elevated C-14 content found by Cowan et al was suggested in 1977 by John Brown and David Hughes of the University of Sheffield [4], who pointed out that sufficient neutrons to account for the American radiocarbon data could have come from the hot plasma generated by a comet's passage.
		Another spectacular explanation for the Tunguska catastrophe was hatched by Jackson and Ryan in 1973.

	Tunguska Event (Site not responding. Last check: 2007-10-20)
		Tunguska is a remote area of north-central Siberia, Russia.
		The prevailing explanation of the Tunguska event was that a stony meteorite had exploded about 8 km above ground, leaving no surface depression and little debris but resulting in a shock wave that accounted for the terrible destruction.
		In later trips to map the zone and collect samples, some scientists found tiny spherules in the ground or small pieces embedded in trees but not all researchers were convinces these are pieces of space debris.

		To explain the peculiar pattern in which energy was deposited at the Tunguska site, many investigators have favored the explosion of a comet with such a low density that it would rapidly decelerate and come to a stop in the atmosphere.
		Thus, a stony asteroid about 30 meters in diameter and moving at 15 kilometers per second would disintegrate at roughly the same height at which the Tunguska object apparently exploded, whereas an iron-rich asteroid would explode too low - if at all - and a carbonaceous asteroid would explode too high.
		To improve estimates of the probability of atmospheric explosions or direct impacts caused by cosmic projectiles striking Earth, Chyba and his colleagues intend to use their computer model to check systematically the fates of different types of objects over a wide range of sizes as they enter the atmosphere.

	Tunguska event of 1908 was to be of geophysical origin!
		Tunguska event in place and in time coincided with a strong upsurge of tectonic activity on regional and (partly) global levels.
		It is based on the fact that the Tunguska spacebody explosion stimulation undertaken by Victor Korobeinikov with his co-workers has shown the internal energy of the spacebody to be commensurate with its kinetic energy to produce the existent forest fall (otherwise the hypothetical meteoroid could not "explode" switfly enough)[6].
		According to Zotkin, Nikolaev, and Peskov [2000] experiments with 26 trees in the epicenter of Tunguska event have estimated an average wind speed to uproot a tree in the epicenter's area as low as of 26 m/s (the rather low value is probably due to a shallowness of trees roots in the area).

		Unfortunately, his model quickly gained much highly biased publicity proclaiming that the Tunguska mystery finally had been solved, and that the possiblility of the object's identity being of cometary origin could be categorically ruled out.
		At this stage of the Tunguska investigations the comet and asteroid theories appear to be the most promising, but the matter is far from being closed, and annual expeditions to the Tunguska site will most likely continue.

		The Stony Tunguska (Russian: Подкаменная Тунгуска, Podkamennaya Tunguska, literally Understone Tunguska) is a river in Siberia; it is a right tributary of the Yenisei and has a length of 1865 km.
		The name of the river comes from the fact that its significant stretches flow under pebble fields without open water.

		The so-called "Tunguska Event" or "Tunguska Blast" (so named for the rural region near the Stony Tunguska River devastated by the explosion) has since become famous among both astronomy aficionados and conspiracy theorists, often blurring the line between science fiction and science fact.
		Moreover, when the Kulik expedition finally reached the Tunguska blast epicenter in 1927, the mineralogist noted a group of trees at the center of the damage area that remained standing straight up, while everything around them lay pressed flat in an expansive butterfly-wing pattern.
		While conspiracy theorists still hold to many wild explanations for the Tunguska Event—including the explosion of an alien spacecraft—scientists have largely divided into two camps of theories: the comet or the meteorite.
