"On March 1, 1954, U.S. bomb-makers caught up by unleashing from Bikini Atoll a deliverable hydrogen weapon, code-named Bravo, its 15 megatonnage making it nearly one and a half times the yield of the Mike shot. Bravo was the most powerful U.S. bomb ever detonated and one equivalent to 1,000 Hiroshima-sized bombs, according to U.S. government documents released in 1994. Weisgall observes, "Hiroshima paled in comparison to Bravo, which represented as revolutionary an advance in explosive power over the atomic bomb as the atomic bomb had over the conventional weapons of World War II." . . .
The Runit Island entombment is of special interest because a nuclear-waste crypt is now being finished 800 miles from Honolulu to bury plutonium-laced materials under a cap of coral soil at Johnston Island, where four failed nuclear-tipped missile shots in 1962 showered the atoll and waters with radioactive debris.
