Leading experts give an overview of very low frequency radio astronomy. They present for the first time in a single conference the astrophysical need for and possible instrumentation for implementing ground-based, ground-to-space, space-based, and lunar-based observations. The papers cover a wide range of topics such as solar astronomy, planetary science, supernova remnants, pulsars, interstellar thermal material, interstellar plasma refraction and diffraction, cosmic rays, extragalactic radio galaxies and quasars, ancient "fossil" radio sources, and new, coherent emission mechanisms.

Urban seismic risk is growing worldwide and is increasingly a problem of developing countries. This book focuses on recent urban earthquake safety developments around the world; in particular, it provides approaches and procedures for the creation of earthquake damage scenarios (EDS). The articles will stimulate anyone -- scientist, engineer, government official, business leader, international aid provider -- considering an EDS project for a city, and they list some of the questions that should be asked, suggest methods of answering them, and describe some advantages and disadvantages of different approaches. Two articles discuss how the above strategies fared in a pilot EDS project nearing completion in Quito, Ecuador. Finally, authors from fourteen other earthquake-threatened cities in developed and developing countries attempt to summarize the earthquake safety of their cities. In the context of their particular social, economic, political, and technical settings, they discuss needs and approaches to reducing earthquake risk.

An international treaty banning the testing of any nuclear device in any environment - a comprehensive test ban treaty (CTBT) - has been on the political agenda for nearly 40 years. Objections to a CTBT have been political, technical, or a combination of both. However, the possibilities seem better after the end of the Cold War. In the prevailing, cooperative disarmament climate a CTBT appears likely to be approved by most countries in 1996. Hence the great current interest in monitoring technologies and capabilities. Such issues are comprehensively addressed here, a preamble being devoted to the political developments and setbacks over the past 40 years. Since seismic means are considered the dominant monitoring element, they are explored in detail. Contributions cover network deployments, advanced signal processing, wave propagation in heterogeneous media, and seismic source representations, and a variety of techniques for source classification (including neural networks). Complementary monitoring techniques, such as hydroacoustics, radionuclides and infrasound, are also summarised. The IAEA operation for monitoring compliance with the Non-Proliferation Treaty is also presented. The book also includes eyewitness accounts of the Soviet 50 Mt megabomb development and test, as well as the efforts made by the state to monitor the nuclear test programmes of the western powers. Includes some 33 articles written by distinguished scientists active in CTBT monitoring research for decades.
