The Tunguska Event: A Mysterious Siberian Explosion
On June 30, 1908, a massive explosion rocked Siberia, near the Podkamennaya Tunguska River. Believed to be caused by an asteroid or comet fragment exploding in the atmosphere, at an altitude of 5 to 10 kilometers, the blast flattened over 2,000 square kilometers of forest, toppling millions of trees. The force was estimated to be equivalent to 10-15 megatons of TNT, yet no impact crater was ever found. This enigmatic event remains one of Earth's largest recorded impact events and a subject of scientific fascination.
