[Some really interesting footage here. I've often wondered about the possibility of nuclear explosions creating tsunamis. And it's possible. This is a small one with only 12 feet wave height. But the Russians have a bomb that can apparently create a tsunami 500m high which would wipe out all of New York in one fell swoop. I don't think the nuclear tsunamis are that impressive. They won't be used much in an actual war. Jan]

500 Feet Deep Water Tsunami Nuclear Atomic Bomb Testing Remastered footage

Operation Wahoo shot :
The nuclear explosion was carried out in open ocean outside of Enewetak. This nuclear test codenamed Wahoo was the first underwater test in the Operation Hardtack series. This test could be considered a continuation of the Wigwam nuclear blast (a deep water nuclear test 500 nautical miles (930 km; 580 mi) off the coast of San Diego).[8] Like its predecessor, the Wahoo shot was a scientific program that studied the effects of an underwater nuclear blast on Navy systems. The nuclear device was positioned 500 feet (150 m) deep in the Pacific Ocean. This deep water test required precise targeting arrays to be set up around the blast location, which presented unique problems for the arrays as the winds, sea currents and tides needed to be within certain limits for the data to be accurate. Testing arrays were placed at depths of 400 to 800 fathoms (2400 to 4800 feet, 732 to 1463 meters) around the nuclear device. The deep water mooring systems needed for the test proved to be difficult to position, leading many analysts to believe the data skewed. The target ships to be used for this program consisted of three destroyers, an active submarine, a submarine mockup used in Wigwam tests, and a merchant marine ship.[4]:225 It was predicted that no air blast or thermal effects would be presented from the underwater blast. The fallout from the blast was also predicted to stay within the target array due to the southwest surface winds.
