The ultimate weapon: Nuclear tsunami bombs?

Back in 2006, the Egyptian weekly Al Osboa reported that American and Israeli nuclear testing had caused an earthquake in the Indian Ocean. The 2004 earthquake triggered a tsunami that killed more than 200,000 people.

The oldest conspiracies are the easiest to debunk. There is just no explosive powerful enough—atomic or otherwise—that can displace the amount of water required to create waves powerful enough to destroy cities.

The Allies carried out a lot of far-out experiments during World War II. One of the most obscure ones is New Zealand’s Project Seal, which allegedly tried to generate a tsunami with explosives.

It was the brainchild of Thomas Leech, a professor at Auckland University. Leech detonated explosives off the coast of the Whangaparaoa Peninsula in 1944 and 1955, according to reports dating back to the late 1990s in the New Zealand Herald.
