The Tunguska Incident: Siberia's Unexplained Megablast

On June 30, 1908, an explosion 1,000 times more powerful than the Hiroshima bomb detonated over remote Siberia, flattening 80 million trees across 830 square miles. No crater. No debris. After 117 years, the cause remains hotly debated.

The event is classified as an atmospheric airburst caused by a stony asteroid approximately 50-60 meters in diameter entering Earth's atmosphere at approximately 27 km/s (Mach 80). The object is believed to have detonated at an altitude of 5-10 kilometers, converting its kinetic energy into a thermal flash and supersonic shockwave without surface impact. The absence of significant meteoritic debris is attributed to complete vaporization during atmospheric entry. NASA designates this as the largest impact event in recorded human history.

Butterfly-Shaped Forest Destruction Pattern

Butterfly-Shaped Forest Destruction Pattern

Soviet mineralogist Leonid Kulik's 1927 expedition documented a distinctive "butterfly-shaped" pattern of devastation spanning approximately 70 km across and 55 km longβ€”totaling 2,150 kmΒ² (830 sq mi) of flattened taiga with an estimated 80 million trees felled. The "wings" represent areas where the blast wave expanded perpendicular to the object's flight path, while the narrow central "body" marks the trajectory. Trees display a subtle "herring-bone" pattern caused by interaction between the spherical blast wave and the conical bow wave traveling ahead of the object.
