Tunguska event, enormous explosion that is estimated to have occurred at 7:14 AM plus or minus one minute on June 30, 1908, at an altitude of 5–10 km (15,000–30,000 feet), flattening some 2,000 square km (500,000 acres) and charring more than 100 square km of pine forest near the Podkamennaya Tunguska River in central Siberia (60°55′ N 101°57′ E), Russia. The energy of the explosion is estimated to have been equivalent to the explosive force of as much as 15 megatons of TNT—a thousand times more powerful than the atomic bomb dropped on Hiroshima, Japan, on August 6, 1945.
Read “The fire came by”. Can’t remember the author.
Give us the link if it is really so useful, comrade.
The Fire Came By, by John Baxter (Australia). I looked it up for you all. Synopsis and amazon purchase links. It is about this incident and suspects it to be a nuclear disaster caused by a crashing ufo. https://www.goodreads.com/en/book/show/1080031
