Volcanic seismology represents the main, and often the only, tool to forecast volcanic eruptions and to monitor the eruption process. This book describes the main types of seismic signals at volcanoes, their nature and spatial and temporal distributions at different stages of eruptive activity. Following from the success of the first edition, published in 2003, the second edition consists of 19 chapters including significant revision and five new chapters. Organized into four sections, the book begins with an introduction to the history and topic of volcanic seismology, discussing the theoretical and experimental models that were developed for the study of the origin of volcanic earthquakes. The second section is devoted to the study of volcano-tectonic earthquakes, giving the theoretical basis for their occurrence and swarms as well as case stories of volcano-tectonic activity associated with the eruptions at basaltic, andesitic, and dacitic volcanoes. There were 40 cases of volcanic eruptions at 20 volcanoes that occurred all over the world from 1910 to 2005, which are discussed. General regularities of volcano-tectonic earthquake swarms, their participation in the eruptive process, their source properties, and the hazard of strong volcano-tectonic earthquakes are also described. The third section describes the theoretical basis for the occurrence of eruption earthquakes together with the description of volcanic tremor, the seismic signals associated with pyroclastic flows, rockfalls and lahars, and volcanic explosions, long-period and very-long-period seismic signals at volcanoes, micro-earthquake swarms, and acoustic events. The final section discuss the mitigation of volcanic hazard and include the methodology of seismic monitoring of volcanic activity, the examples of forecasting of volcanic eruptions by seismic methods, and the description of seismic activity in the regions of dormant volcanoes.

This book will be essential for students and practitioners of volcanic seismology to understand the essential elements of volcanic eruptions.
Provides a comprehensive overview of seismic signals at different stages of volcano eruption.Discusses dozens of case histories from around the world to provide real-world applications.Illustrations accompany detailed descriptions of volcano eruptions alongside the theories involved.

The book requires only rudimentary physics knowledge but ability to program computers creatively and to keep the mind open to simple and not so simple models, based in individuals, for the living world around us.
* Interdisciplinary coverage
* Research oriented
* Contains and explains programs
* Based on recent discoveries
* Little special knowledge required besides programming
* Suitable for undergraduate and graduate research projects

Monitoring drought’s slow evolution and identifying the end of a drought is still a big challenge for scientists, natural resource managers, and decision makers. This comprehensive two-volume set with contributions from over 200 experts, and featuring case studies representing numerous countries throughout the world, discusses different aspects of drought from types, indices, and forecasting to monitoring, modeling, and mitigation measures. It also addresses how climate change is impacting drought and decision-making concluding with lessons learned about science, policy, and managing uncertainty. Features: Provides a global perspective on drought prediction and management and a synthesis of the recent state of knowledge. Covers a wide range of topics from essential concepts and advanced techniques for forecasting and modeling drought to societal impacts, consequences, and planning Presents numerous case studies with different management approaches from different regions and countries. Addresses how climate change impacts drought, the increasing challenges associated with managing drought, decision making, and policy implications. Includes contributions from hundreds of experts around the world. Professionals, researchers, academics, and postgraduate students with knowledge in Environmental Sciences, Ecology, Agriculture, Forestry, Hydrology, Water Resources Engineering, and Earth Sciences, as well as those interested in how climate change impacts drought management, will gain new insights from the experts featured in this two-volume handbook.

Agricultural ecology, or agroecology, deals in general with the structure and function of agroecosystems at different levels of resolution. In this text/reference, the authors describe in terms of agroecology the tropical environments of sub-Saharan Africa, Southeast Asia, and Latin and Central America, focusing on production and management systems unique to each region.

Located on the Bay of Fundy, the St. Andrews Biological Station is Canada's oldest permanent marine research institution. A Century of Maritime Science reviews the fisheries, environmental, oceanographic, and aquaculture research conducted over the last hundred years at St. Andrews from the perspective of the participating scientists. Introductory essays by two leading historians of science situate the work at St. Andrews within their historical context. With topics including the contributions of women to the early study of marine biology in Canada; the study of scallops, Atlantic salmon, and paralytic shellfish poisoning; and the development of underwater camera technology, A Century of Maritime Science offers a captivating mixture of first-hand reminiscences, scientific expertise, and historical analysis.

Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 138.Subduction zones helped nucleate and grow the continents, they fertilize and lubricate the earth's interior, they are the site of most subaerial volcanism and many major earthquakes, and they yield a large fraction of the earth's precious metals. They are obvious targets for study--almost anything you learn is likely to impact important problems--yet arriving at a general understanding is notoriously difficult: Each subduction zone is distinct, differing in some important aspect from other subduction zones; fundamental aspects of their mechanics and igneous processes differ from those in other, relatively well-understood parts of the earth; and there are few direct samples of some of their most important metamorphic and metasomatic processes. As a result, even first-order features of subduction zones have generated conflict and apparent paradox. A central question about convergent margins, for instance--how vigorous magmatism can occur where plates sink and the mantle cools--has a host of mutually inconsistent answers: Early suggestions that magmatism resulted from melting subducted crust have been emphatically disproved and recently just as emphatically revived; the idea that melting is fluxed by fluid released from subducted crust is widely held but cannot explain the temperatures and volatile contents of many arc magmas; generations of kinematic and dynamic models have told us the mantle sinks at convergent margins, yet strong evidence suggests that melting there is often driven by upwelling. In contrast, our understanding ofwhy volcanoes appear at ocean ridges and "hotspots"--although still presenting their own chestnuts--are fundamentally solved problems.
