Prof. Sakuhana first mentioned the fall of the great meteorite in Russia. “The meteorite was about 17 meters in size, but the town was wrapped in a white flash of light, and the subsequent shock wave caused the site to panic. It was.In fact, in Russia in 1908 about 50 meters of meteorite has fallen to Siberia, an unmanned area at the same latitude of 60 degrees north.“If it was out of time and it had fallen into a major European city at 60 degrees north latitude, the World War I might not have happened because of the response.”The meteorite fall to the Yucatan Peninsula, Mexico, which caused the dinosaurs to be destroyed 65 million years ago, caused a tsunami of 10 to 15 kilometers in magnitude and more than 11 meters.
