The Tunguska event, also known as the Tunguska explosion, was a powerful explosion that occurred on June 30, 1908 in a remote area of Siberia in Russia, called Podkamennaya Tunguska. It is likely the largest event of its kind in history, causing enormous damage to the Earth’s surface and leaving many questions about its cause.
The explosion caused the destruction of a vast forest area of nearly 2,000 square kilometers. The fireball was visible up to a distance of 1,000 kilometers from the epicenter and caused a sound audible as far away as the observatory in Irkutsk, 3,000 kilometers away. The consequences of the explosion were not immediate, as the area was uninhabited at the time, but later surveys found traces of a large fire and chemical changes in the soil.
The cause of this explosion is still not clear. Various theories have been proposed, such as the impact of an asteroid or comet, the explosion of methane gas, or even a test of some secret weapon. However, none of these theories has been definitively confirmed and the cause of the Tunguska event remains a mystery.
