1. The Tunguska Event (1908)
On June 30, 1908, a massive explosion occurred over Siberia, flattening approximately 2,000 square kilometers of forest. This event, known as the Tunguska Event, is believed to have been caused by the airburst of a meteoroid or comet entering Earth’s atmosphere. Despite extensive studies, no impact crater was found, making it one of Earth’s most powerful recorded explosions. Scientists estimate its energy at 10-15 megatons of TNT. (nasa.gov)
