Wired.com : The long-distance scientific recordings of the blast wave from the first hydrogen bomb test have been rediscovered in a formerly classified safe at Columbia University.On 1 November 1952, the US created a 10-megaton blast that set off a low-frequency sound wave , which was recorded halfway around the world at special listening stations designed by the Lamont Geological Observatory in Palisades, New York.It was the first time a nuclear explosion had been detected from such a long distance and it marked the beginning of international test monitoring, a key element of nuclear nonproliferation plans.Related Link Build your own microbarograph
