EXPERTS’ PANEL: One year after Fukushima – The CTBTO’s contributions to mitigating natural and nuclear disasters

UPDATE – 9 March 2012

Broadcast quality video is now available for broadcasters. It includes a new animation showing the spread of radioactive releases, CTBTO monitoring stations in Japan and the operations room of the Earthquake and Tsunami Division of the Japan Meteorological Agency.  It’s accompanied by a shotsheet with a storyline.  Contact Kirstie Hansen (, Tel. +43 1 26030-6540) for details.

Initial Post – 7 March 2012:

Apart from detecting nuclear tests, each of CTBTO’s four monitoring technologies – seismic, hydroacoustic, infrasound and radionuclide – provides States with real-time, high-quality data that can help save lives in the event of disasters such as tsunamis and nuclear accidents.

The colloquium ‘CTBTO Past and Future Contributions to Emergency Preparedness: Fukushima Case Study’ will discuss, in particular, the International Monitoring System’s capability to enable national authorities to issue timely tsunami warnings. It will also assess the dispersal of radioactive emissions after a nuclear accident. Japan recently made a large voluntary contribution to further enhance the CTBTO’s capabilities to monitor airborne radioactivity.

WhenFriday, 9 March 2012, from 10:00 to 13:00

WhereVienna International Centre, M Building, room M3 – Vienna, Austria.
The event is open to the media and the public. For those who cannot attend, it will also be live-streamed on the CTBTO’s website.

Read more about the programme, registration issues and a note for broadcasters in the 7 March media advisory, here.

Speakers – Ambassador Toshiro Ozawa, Permanent Representative of Japan to the International Organizations in Vienna, Deputy Director General Denis Flory of the International Atomic Energy Agency (IAEA), Wolfgang Weiss, Chair of the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) and  representatives from the World Meteorological Organization (WMO), the World Health Organization (WHO), and from UNESCO’s Intergovernmental Oceanographic Commission (IOC) will share their perspectives on the disaster mitigation efforts and how CTBTO data were used.  Experts, scientists and lead analysts from the CTBTO will share their first-hand experiences and offer some rare and valuable insights into how the system performed.  The floor will be open for questions from those attending the event.

The Comprehensive Nuclear-Test-Ban Treaty (CTBT) bans all nuclear explosions by everyone, everywhere. A verification regime with over 300 sensors monitors the globe around the clock for nuclear explosions in order to detect violations of the Treaty. During the Tohoku earthquake and nuclear accident, the CTBTO data helped authorities in Japan and other countries to issue timely tsunami warnings and later helped monitor radioactive releases from the damaged Fukushima power plant.
