Nuclear Test Ban Treaty Monitoring

In 1996, the UN member states drafted an agreement banning nuclear tests. An International Monitoring System (IMS) coordinated in Vienna was established to control adherence to this agreement. The IMS monitors seismological, hydroacoustic, radionuclide and infrasound data and associated communications, supported by the Technical Secretariat's International Data Centre (IDC).

The SED contributes by providing data recorded by a purpose-built seismic station near Davos which, for example, recorded ground shaking 12 minutes after the nuclear test conducted in North Korea in January 2016.
