Following the pattern in previous issues, the current issue of CTBTO Spectrum introduces the Treaty-defined North America and Western Europe geographical region. It is shown that this region with its 28 States is of great significance to the Treaty. All States of the region have signed the Treaty. With the exception of the United States of America, all States of the region have also ratified the Treaty. Since all States in the Treaty-defined Eastern Europe geographical region have ratified the Treaty as well, all States in Europe are now parties to the Treaty.
Following the catastrophe caused by the Indian Ocean tsunami in December 2004, the application of CTBT verification data for disaster prevention and mitigation was discussed intensely. CTBTO Spectrum looks at this discussion and the ensuing test exercises which culminated in the decision by the CTBTO Preparatory Commission to provide real-time data to selected tsunami warning centres.
In September 2006, the CTBTO marked the tenth anniversary of the adoption of the CTBT by the United Nations General Assembly and the Treaty's opening for signature. Michael Crowley, Executive Director of the Verification Research, Training and Information Centre (VERTIC), uses this occasion to look at past achievements and future challenges. He says that the claimed test by North Korea should motivate States Signatories to redouble their efforts in bringing the Treaty closer to entry into force. Two events this year, the NPT Preparatory Commission in April/May and the Article XVI Conference in September, should be seen as important opportunities to make real advances in this regard.
Under the heading "Verification highlights", the newsletter presents updates on the work of the Provisional Technical Secretariat, including the installation of an infrasound station on Ascension Island and ongoing preparations for a large-scale field exercise to test on-site inspection procedures.
