On 30 June 1908, just after 7 AM (all dates correspond to our Gregorian calendar), an explosion occurred in the harsh forests in Siberia near the Tunguska river. The explosion happened over an area that is nearly unpopulated, so apart from an estimated 80 million trees (and, we suppose, the wildlife in that area of 2150 km²) only three humans died in the event that would likely have been a major catastrophe if it had happened over a densely populated area.| Photos: Pixabay
