| Scope (Session Description) |
The 1996 Comprehensive Nuclear-Test-Ban Treaty (CTBT) bans nuclear test explosions underground, in the ocean, and in the atmosphere. To ensure treaty compliance around the globe, the CTBT comprises a unique and comprehensive verification regime: The International Monitoring System (IMS). The IMS consists of 337 stations worldwide and uses four state-of-the-art monitoring technologies: 1. Seismic, 2. Hydroacoustic, 3. Infrasound, and 4. Radionuclide. As of 2023, more than 90-% of the facilities are operational, transmitting real-time data to the International Data Centre in Vienna, Austria.
In addition to detecting nuclear test explosions, the vast amount of data collected by the IMS gives rise to a range of civil and scientific applications, such as the study of tsunami events, earthquakes, volcanoes, climate change, the dispersion of radionuclide particles, and many other geophysical phenomena.
This session aims to bring together stakeholders from National Data Centers, station operators, and members of the research community, serving as a forum for discussion on all aspects of the IMS and test-ban treaty monitoring. Topics may include - but are not limited to - the status of the network in Japan and elsewhere, research outcomes from IMS data, and perspectives on future development of CTBT technologies, algorithms, and capacity building.
Presentations focusing on regional or global monitoring systems other than the IMS are welcome, especially when similar technologies are used (seismic, hydroacoustic, infrasound, and radionuclide). Contributions from early-career scientists are highly encouraged. |
