Video Flagged Dead

Largest underground nuclear test in US history

"The ground riseth beneath."

A longer version of a previous sift.

From YT: Cannikin was detonated on 6 November 1971. The announced yield was "less than five" megatons -- the largest underground nuclear test in US history. (Estimates for the precise yield range from 4.4 Mt to 5.2Mt.) The ground lifted 20 feet, caused by an explosive force equivalent almost 400 times the power of the Hiroshima bomb. Subsidence and faulting at the site created a new lake, over a mile wide. The explosion caused a seismic shock of 7.0 on the Richter scale, causing rockfalls and turf slides of a total of 35,000 square feet.

Hurray for the good guy! For the nation with the largest stockpile of weaponry capable of wiping out the planet, and the only nation to actually use nukes against a civilian population resulting in mass casualties and decades of post nuclear deformities!
