The International Monitoring System of the CTBTO is designed to detect nuclear explosions, anywhere, anytime. It is so sensitive, it can pick up the smallest seismic event and trace the dispersal of miniscule amounts of radioactive substances. In March 2011, when Japan was struck by a chain of devastating events -- earthquake, tsunami and nuclear accident -- CTBTO's monitoring stations around the world recorded and tracked the unfolding crisis, and kept authorities informed. In the days and weeks that followed, CTBTO's global warning system underlined its importance to disaster prevention and mitigation.
