While the detection of nuclear explosives in the atmosphere far from a test site, and in space, was not an issue, underground explosions had the potential to be muffled or detected as an earthquake. Maddock thus enhanced instruments to amplify the signal caused by an explosion, allowing for detection of explosions thousands of kilometres away. In order to attain political control of nuclear explosions, such equipment would be required in multitudes, resulting in the 1973
