Monitoring the Comprehensive Nuclear Test Ban Treaty (CTBT) by seismic means will require identification of seismic sources at magnitude levels where industrial explosions (primarily, mining blasts) may comprise a significant fraction of the total number of events recorded, and may for some countries dominate the seismicity. Thus, data on blasting practice have both political significance for the negotiation of treaties involving seismic monitoring of nuclear tests, and operational applications in terms of establishing monitoring and inspection needs on a mine-by-mine basis. While it is generally accepted that mining explosions contribute to seismicity at lower seismic magnitudes (less than about magnitude 3.5), the rate of mining seismicity as a function of seismic magnitude is unknown for most countries outside the U.S. This results in a large uncertainty when estimating the task of discriminating nuclear explosions from chemical explosions and earthquakes, by seismic means, under a comprehensive nuclear test ban. This uncertainty directly affects estimates of seismic network enhancements required to achieve treaty verification requirements at magnitudes less than about 3.5. 24 refs., 64 figs., 11 tabs.

We have recently begun a project to document the numbers of mine blasts that will be detected teleseismically, and at regional distances, by seismograph networks used to monitor compliance with a Comprehensive Test Ban Treaty. We plan to study blasting in the United States, in countries of the former Soviet Union, and in Australia, Canada, China, and Korea. Knowledge of mine blast statistics is needed in order to plan efforts in discrimination, recognizing that in general it is more difficult to tell the difference, from seismic data, between underground nuclear and chemical explosions, than between underground nuclear explosions and earthquakes. If the number of large mine blast signals is large, the effort to analyse such signals could swamp discrimination programs. So far we have acquired and analysed mine blast data from eight different areas of the former Soviet Union. We have established as a total for all these regions that only on the order of 30 blasting events per year have K (energy class) value of 9 or greater - corresponding to mb around 3.35 or greater. Also, the slope of the frequency-magnitude relation is much steeper for mine blasting signals, than for earthquakes (the b-value is greater than 2 for blasting, and around unity for earthquakes). This latter result is good from the perspective of concern over very large blasts - because it implies there are very few such events. It also indicates that the number of blast signals rises very rapidly as one considers events with magnitude below about mb 3.25.

Pure appl. geophys., by 161 nations. Entry of the treaty into force, however, is still uncertain since it requires ratification by all 44 nations that have some nuclear capability and, as of 15 June 2001, only 31 of those nations have done so. Although entry of the CTBT into force is still uncertain, seismologists and scientists in related fields, such as radionuclides, have proceeded with new research on issues relevant to monitoring compliance with it. Results of much of that research may be used by the International Monitoring System, headquartered in Vienna, and by several national centers and individual institutions, to monitor compliance with the CTBT. New issues associated with CTBT monitoring in the 21st century have presented scientists with many new challenges. They must be able to effectively monitor com pliance by several countries that have not previously been nuclear powers. Effective monitoring requires that we be able to detect and locate much smaller nuclear events than ever before and to distinguish them from small earthquakes and other types of explosions. We must have those capabilities in regions that are seismically active and geologically complex, and where seismic waves might not propagate efficiently.

This unique book explores the problems of the national crisis management system in Russia, a country undergoing political, social and economic transition and one which is also prone to natural and man-made disasters. In detailing policy, institutional and legal issues and illustrating a number of case studies, the authors offer new ways of resolving the effects of disasters as well as increasing resilience by improving our understanding of the risks and vulnerabilities. In the book six chapters offer case studies of various types of disaster written in a unique collaboration between Russian scientists, Russian policy makers and Swedish scholars. Other chapters relate the role of mass media in Russian society and policy development. Taken together the book details changes in a crisis management system, policy and approach in a country that has undergone rapid fundamental political economic and social change.

In September 1996, the United Nations General Assembly adopted the Comprehensive Nuclear-Test-Ban Treaty (CTBT), prohibiting nuclear explosions worldwide, in all environments. The treaty calls for a global verification system, including a network of 321 monitoring stations distributed around the globe, a data communications network, an international data center, and onsite inspections, to verify compliance. The problem of identifying small-magnitude banned nuclear tests and discriminating between such tests and the background of earthquakes and mining-related seismic events, is a challenging research problem. Because they emphasize CTBT verification research, the 12 papers in this special volume primarily addresses regional data recorded by a variety of arrays, broadband stations, and temporarily deployed stations. Nuclear explosions, earthquakes, mining-related explosions, mine collapses, single-charge and ripple-fired chemical explosions from Europe, Asia, North Africa, and North America are all studied. While the primary emphasis is on short-period, body-wave discriminants and associated source and path corrections, research that focuses on long-period data recorded at regional and teleseismic distances is also presented Hence, these papers demonstrate how event identification research in support of CTBT monitoring has expanded in recent years to include a wide variety of event types, data types, geographic regions and statistical techniques.

This book was prepared for publication by an International Working Group of experts under the auspices of COGEOENVIRONMENT - the Commission of the International Union of Geological Sciences (lUGS) on Geological Sciences for Environmental Planning and lUGS-GEM (Commission on Geosciences for Environmental Management). The main aim of the Working Group "Geology and Ecosystems" was to develop an interdisciplinary approach to the study of the mechanisms and special features within the "living tissue - inert nature" system under different regional, geological, and anthropogenic conditions. This activity requires international contributions from many scientific fields. It requires efforts from scientists specializing in fields such as: environmental impacts of extractive industries, anthropogenic development and medical problems related to geology and ecosystem interaction, the prediction of the geoenvironmental evolution of ecosystems, etc. The Working Group determined the goal and objectives of the book, developed the main content, discussed the parts and chapters, and formed the team of authors and the Editorial Board. The Meetings of the Working Group (Vilnius, Lithuania, 2002 and Warsaw-Kielniki, Poland, 2003) were dedicated to discussion and approval of the main content of all chapters in the Book.
