+The Tunguska Event was a massive, mysterious explosion near the Podkamennaya Tunguska River in [Siberia](/wiki/siberia), Russia, on June 30, 1908. It flattened an estimated 80 million trees, likely caused by the atmospheric airburst of a large [meteor](/wiki/meteor) or comet. No impact crater was ever found, making it one of Earth's most significant yet puzzling impact events.
