Largest underground nuclear test in US history

1 decade 5 years 11 months 3 weeks ago

"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.
