Forensic seismology
Forensic seismology is the forensic use of the techniques of seismology to detect and study distant phenomena, particularly explosions, including those of nuclear weapons. Because of the efficiency with which seismic waves propagate through the Earth and the technical difficulties of decoupling explosions to diminish their seismic radiation, forensic seismology is a critical technique in the enforcement of bans on underground nuclear testing. In addition to nuclear explosions, the signatures of many other kinds of explosions can also be detected and analyzed by forensic seismology, and even other phenomena such as ocean waves (the global microseism), the movement of icebergs across the sea floor or in collision with other icebergs, or explosions within submarines. Organizations with expertise in forensic seismology include AWE Blacknest, Los Alamos National Laboratory, Sandia National Laboratory, and Lawrence Livermore National Laboratory. Seismic detection of nuclear detonations Forensic Seismology is one of several other methods used by the global community to determine compliance with the Comprehensive Nuclear Test-Ban Treaty (CTBT). A network of approximately 170 seismic stations, along with data generated from sources such as infrasound, hydroacoustics, and radionuclide detection, is used to identify and locate nuclear detonations. Forensic seismology is specifically used to locate nuclear detonations
