International Monitoring System

The International Monitoring System (IMS) is a global network of sensors and stations established by the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) to detect nuclear explosions worldwide. It uses various detection methods, such as seismic, acoustic, and radionuclide sensors, to identify signs of underground, underwater, or atmospheric nuclear tests. The goal is to promote disarmament, ensure compliance with nuclear test bans, and enhance international security by providing reliable, real-time data to verify treaty adherence. The IMS’s sophisticated technology and worldwide coverage make it a key tool for global nuclear non-proliferation efforts.
