Details

The Tunguska meteoroid was the object that exploded over Siberia in 1908. The airburst flattened about 80 million trees across more than 2,000 square kilometers but left no impact crater, demonstrating how destructive an atmospheric breakup can be.

Unlike the instrument-rich Chelyabinsk event a century later, Tunguska must be reconstructed from eyewitness accounts and the pattern of forest damage. Current evidence favors an asteroid airburst, although the object left no recoverable main mass. Its effects remain a benchmark for estimating the regional hazard from bodies tens of meters across.
