What is thought to have caused the Tunguska event in 1908?

Though scientific consensus is that the Tunguska explosion was caused by the impact of a small asteroid, there are some dissenters. Astrophysicist Wolfgang Kundt has proposed that the Tunguska event was caused by the release and subsequent explosion of 10 million tons of natural gas from within the Earth’s crust.

What is mysterious about Tunguska?

Because no traces of a meteorite were found, it many scientists concluded that the culprit was a comet. Comets, which are essentially muddy ice balls, could cause such a devastation and leave no trace. But now, 105 years later, scientists have revealed that the Tunguska devastation was indeed caused by a meteorite.

Why is the Tunguska event important?

The study of the Tunguska event is important because past collisions with extraterrestrial bodies have had major effects on the evolution of the earth. Some 4.4 billion years ago, for example, a Mars-size planetoid seems to have struck our young planet, throwing out enough debris to create our moon.

What is the meaning of Tunguska?

Its explosion had a high concentration of energy, approaching that of a nuclear explosion. Also, it was accompanied by ionizing radiation and radioactive fallout.
