The Preparatory Commission for the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) held a special session on 4 March 2005 to consider a possible contribution of the CTBTO Preparatory Commission to a tsunami warning system.  The decision of the Preparatory Commission made at the special session on 4 March 2005 is attached.  The Provisional Technical Secretariat of the Preparatory Commission for the CTBTO will continue to cooperate with UNESCO and the International Oceanographic Commission (IOC) on the possible contribution to a tsunami warning system and will report on developments of the cooperation at the June session of the Preparatory Commission. The Comprehensive Nuclear-Test-Ban Treaty bans any nuclear weapons test explosion in any environment.  Drafted at the Conference on Disarmament in Geneva, and adopted by the General Assembly of the United Nations on 10 September 1996, the Treaty was opened for signature on 24 September 1996 at the United Nations Headquarters in New York.  To date, it has been signed by 175 States and ratified by 120.  It will enter into force when it has been ratified by all 44 States listed in Annex 2 to the Treaty.  Thirty-three of these States have so far deposited their instruments of ratification.

(a)Explore and initially assess with national authorities and international tsunami warning organizations recognized by UNESCO, upon their request, which data and products might be useful and can be provided by the PTS for tsunami warning. The assessment could include, inter alia, technical tests to facilitate the requesting organizations in addressing the nature, quality, quantity, timeliness and usefulness of the information provided. The technical tests could include primary seismic and hydroacoustic data, and, upon request, auxiliary seismic data, from selected stations, and results of automatic analysis of such data. The tests could also identify modalities for the compilation and forwarding of data and products by the PTS;
(b)Examine the legal framework, with reference to the Treaty, its Protocol and the Resolution Establishing the Preparatory Commission for the Comprehensive Nuclear-Test-Ban Treaty Organization, administrative and budgetary implications, as well as matters related to confidentiality. For the provision of PTS data and products on a test basis, the PTS should develop provisional arrangements with the requesting organizations;
(c)Examine and propose capacity building measures for the establishment and/or strengthening of National Data Centres in developing countries. The Preparatory Commission also decides to task the PTS to: Provide a written report on these matters to Part II of the Twenty-Fifth Session of WGB (29 August to 9 September 2005).
