Recent Advances in Nuclear Explosion Monitoring

This topical volume focuses on the most recent advances that have been achieved in relevant fields of research of nuclear test ban monitoring, including seismology, infrasound- and hydro-acoustics, as well as nuclear physics and atmospheric backtracking. This research has been presented during the special sessions on "Research and Development in Nuclear Explosion Monitoring" convened during the 2007 and 2008 General Assemblies of the European Geosciences Union (EGU). The special sessions were introduced after the Preparatory Commission for the Comprehensive Nuclear Test-Ban Treaty Organization (CTBTO Prepcom) had convened a scientific symposium in 2006 on "CTBT: Synergies with Science 1996-2006 and beyond" marking the tenth anniversary of the United Nations General Assembly's adoption of the CTBT Treaty. With regard to the seismo-acoustic fields several papers provide important updates on advances made in these fields since publication of 'Monitoring the Comprehensive Nuclear-Test-Ban Treaty' (see PAGEOPH topical volumes 158-159, 2001-2002). Moreover, this topical volume expands on these publications by including radionuclide and noble gas monitoring, as well as atmospheric transport modeling. In these two areas, significant progress has been made in recent years. Two papers studying the 2006 North Korean nuclear test elucidate how progress made in the relevant fields has allowed for a good understanding on the characteristics of this underground nuclear test.
