About vDec

The International Monitoring System (IMS) is a global network that uses state-of-the-art seismic, hydroacoustic, infrasound and radionuclide facilities to monitor the Earth, oceans and atmosphere 24/7 for signs of nuclear explosions.

The data recorded by the system are widely considered to be unique and a treasure trove of knowledge with a broad range of civil and scientific applications. Today, CTBTO data are not only being used to detect nuclear explosions but also to investigate the impact of climate change, warn about tsunamis or to track radiation on a global scale.

The virtual Data Exploitation Centre (vDEC) provides scientists and researchers from many different disciplines and from around the globe with access to our data to conduct research and to publish new findings. Scientists have the opportunity to meet and exchange knowledge and information at a range of fora, including the CTBTO’s Science and Technology Conference series, workshops and technical meetings, or via this dedicated vDEC page.

The strong relationship between the scientific and technological community and the CTBTO helps to ensure that the IMS remains at the forefront of technological innovation and that no nuclear explosion goes undetected.
