The proliferation of nuclear weapons urged the Superpowers and other nuclear nations to monitor the state of advancement of atomic programmes in foreign countries. A variety of geophysical techniques developed in connection with nuclear testing. In particular, the rise of underground tests propelled the expansion of seismology and world-wide surveillance seismic networks were established to gather data on nuclear explosions.
