On Saturday, November 1, 1952, a momentous event in history took place in total secrecy - the United States detonated the world's first "Super Bomb" at Eniwetok Atoll, Marshall Islands. A thermonuclear device, codenamed Mike, demonstrated the capability of producing a fusion reaction on earth, a process similar to that which powers the sun. This book is a riveting historical account of the Scripps Institution of Oceanography's involvement in that test, because of uncertainty that Mike might blow a section of the atoll away, thus generating a dangerous tsunami. Three days later, a natural earthquake generated a large tsunami in the northwestern Pacific. The author conjectures whether it would have been deemed coincidental had the real tsunami occurred three days earlier.
