	Tunguska event - Wikipedia, the free encyclopedia
		The Tunguska event was an aerial explosion that occurred at 60°55′ N 101°57′ E, near the Podkamennaya (Stony) Tunguska River in what is now Evenkia, Siberia, at 7:17 AM on June 30, 1908.
		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.

	Tunguska (Site not responding. Last check: 2007-10-20)
		Tunguska is a remote, largely uninhabited region in Siberia, Russia, near a river of the same name.
		It is known for an enormous impact event about a quarter after seven 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 Upper (Verkhnyaya), the Stony (Podkamennaya), and the Lower (Nizhnyaya) Tunguska rivers are tributaries of the Yenisei River.

	PRELIMINARY RESULTS FROM THE 1961 COMBINED TUNGUSKA METEORITE EXPEDITION
		The great popular interest in the Tunguska meteorite that arose after the 1958 expedition was to a considerable extent fostered by the fantastic suggestion of a nuclear origin for the explosion, an idea based on factual material of questionable competence.
		The expedition of 1961 was organized on the initiative of the Committee on Meteorites on the basis of a decision taken by the Ninth Conference on Meteorites and the 30 September 1960 Decree of the Presidium of the USSR Academy of Sciences [17].
		Thus the problem of studying the material composition of the Tunguska meteorite is inseparably interwoven with the general study of meteoric dust, and part and parcel thereof.

		Le collisioni tra pianeti e comete sono piuttosto frequenti su scala astronomica: la Terra incontrò una piccola cometa nel 1908, che esplose nella taiga siberiana causando l'evento di Tunguska, che rase al suolo migliaia di chilometri quadrati di foresta.
		Nel 1910 la Terra passò attraverso la coda della Cometa di Halley, ma le code sono talmente immateriali che il nostro pianeta non subì il minimo effetto.

	Tunguska event of 1908 had to be of geophysical origin!
		Since that time the situation with the "meteorite fall" Tunguska rather resembles a pendulum: one group of scientists turns up new strong evidences that Tunguska event couldn't have been caused by an asteroid made of stone or iron, thus it had to be caused a comet.
		Nowadays the situation with so called "Tunguska meteorite" resembles a pendulum: one group of scientists turns up new (and old too) strong evidence that Tunguska couldn't have been an asteroid made of stone or iron, thus it had to be a comet.
		The Tunguska event is also associated with other disturbances and anomalies, as, for example, unusual pattern of seismic manifestations, which also don't conform with the meteorite fall, but unfortunately, I have no time to discuss them.

		A year later, he wrote a story in which the blast at Tunguska was represented as the result of an exploding nuclear power plant of a spaceship from Mars, which was seeking fresh water from Lake Baykal.
		Tunguska was not an isolated event; it could happen again, and we better get ready for it.
		According to a 1978 TV program, "The evidence supported the Soviet contention that Tunguska was the result of a nuclear holocaust," a conclusion directly counter to that of the experimenters themselves and a statement that falsely implies that Soviet scientists in general contended that the event was nuclear in origin.

		The similarity between the geomagnetic effects of the Tunguska Event and of the thermonuclear explosions just mentioned were generally dismissed by the scientific community because of its seeming unliklihood.
		Two phenomena in the history of the Tunguska research are of key importance: 1) The explosion of the cosmic object occurred in the air; and 2) Analysis of the geomagnetic effects of 30 June 1908 recorded by the Irkutsk Observatory.
		Attempts to explain the unusual Tunguska geomagnetic effect, based on hypotheses about the blast wave of the explosion affecting the ionosphere, were criticized in Zolotov's monograph and in a computational paper by Zhuravlev and Demin [Zolotov, 1969; Zhuravlyov et al., 1967].

		Science News: Tunguska: the explosion of a stony asteroid.
		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.
		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 Explosion
		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.

	Great 1908 Tunguska Explosion - UFO Meets Comet?

	The Tunguska Problem: An Anomaly Par Excellence - UFO Evidence
		The point is not only that the Tunguska problem has for many years been one of the favorite research subjects of our institute, or that there are among the members of its Scientific Council a few leading Tunguska researchers.
		At the same time, the amount of the TSB's indirect traces, left after its explosion (beginning with the trees leveled over an area of about 2150 square kilometers and ending with mutations in the pines), also exceeds the entire quantity of all traces of UFO landings ever found (or thought to be found).

		The fuss about the Tunguska problem raised by the mass media irritated the USSR Academy of Sciences and it was therefore decided to find out which of the equally "obvious" pictures of the catastrophe was correct.
		Authors of any hypothesis about the Tunguska phenomenon should understand: if their hypothesis does not explain such well-established empirical facts as the geomagnetic storm after the explosion, anomalies of the thermoluminescence, radiation burn of trees, mutations in pines, etc.—it does not explain the Tunguska event.
