A closer look at “Tunguska Event: What Caused the Mysterious 1908 Atmospheric Explosion Over Siberia?”, exactly as the source publishes it. On the morning of June 30, 1908, a massive atmospheric explosion occurred over the remote Siberian taiga near the Podkamennaya Tunguska River. The blast flattened an estimated 80 million trees across 2,150 square kilometers, yet left no impact crater. Eyewitnesses reported a fireball brighter than the sun and a shockwave that knocked people off their feet hundreds of kilometers away.
Seismic and barometric readings were recorded as far away as Western Europe. The event, now known as the Tunguska Event, remains the largest impact event in recorded history. Scientists generally attribute it to an airburst of a small asteroid or comet, roughly 50–60 meters in diameter, exploding at an altitude of 5–10 kilometers with a force of 10–15 megatons of TNT.
