STATEMENT BY CTBTO EXECUTIVE SECRETARY TIBOR TÓTH ON THE SEISMIC EVENT DETECTED IN NORTH KOREA AS A RESPONSE TO MEDIA QUESTIONS
A verification regime is being built to monitor compliance with the Treaty. Over 85 percent of the 337 facilities in the International Monitoring System are already in place, see interactive map. The Member States are provided with data collected by the monitoring stations, as well as data analyses prepared by the International Data Centre in Vienna, Austria. Once the Treaty has entered into force, an on-site inspection can be invoked in case of a suspicious event.
The North Korean nuclear tests on 9 October 2006 and 25 May 2009 were detected immediately by the CTBTO’s monitoring stations.
