Wahoo and Umbrella were code names for two underwater nuclear tests conducted in 1958. Wahoo was detonated on May 16, 1958 and Umbrella was detonated on June 8, 1958. Pat Bradley, the cameraman who photographed these events recounts his first hand experience of seeing these tests and being on the island as the explosion took place.
Look at the massive volume of water that was thrown up from under the surface... It's mind boggling. What kind of power are we talking about here?
Bleurgh, tidal waves are one of my phobias. Can you imagine, standing at the shore, and looking up to a tidal wave that is, say, ten metres tall - it is just hovering there above you, ominously, menacingly; you know that it is going to break any moment, and it's almost as if the wave itself knows. There isn't enough time to make an escape, your fate is sealed.
Impressive natural force in another sense, though.
