The Tunguska Event: A Cosmic Mystery
On June 30, 1908, near the remote Podkamennaya Tunguska River in Siberia, Russia, an extraordinary explosion shook the Earth. This event, known as the Tunguska event, released energy estimated between 3 and 50 megatons—making it the largest impact event recorded in history. The explosion is believed to have been caused by a meteor air burst. A stony asteroid, about 50–60 meters wide, entered Earth's atmosphere and exploded at an altitude of 5 to 10 kilometers. This massive blast flattened around 80 million trees over a vast area of 2,150 square kilometers (830 square miles), but surprisingly, no crater was found. Despite occurring in a sparsely populated area, the explosion's shockwave was felt far and wide. It created seismic waves that spread across Eurasia, and airwaves reached as far as Germany, Denmark, Croatia, and the UK. The shockwave was equivalent to a 5.0 magnitude earthquake, illustrating the event's incredible power. One of the most intriguing aspects of the Tu...
