Originally published in 1995, Monitoring Active Volcanoes is a comprehensive text which addresses the importance of volcano surveillance in the context of forecasting eruptive activity and mitigating its effects. The traditional core of seismic and ground deformation monitoring is discussed, along with more innovative techniques involving the recording of microgravity and micromagnetic variations, and the changing compositions of volcanic gases and liquids. The role of satellites is stressed, particularly with regard to the capabilities for measuring surface deformation, recognizing thermal anomalies and monitoring gas and ash plumes from space platforms. This book provides an invaluable insight into how and why volcanoes are monitored. It will be of interest to volcanologists, geophysicists and earth scientists.
The monograph covers the fundamentals and the consequences of extreme geophysical phenomena like asteroid impacts, climatic change, earthquakes, tsunamis, hurricanes, landslides, volcanic eruptions, flooding, and space weather. This monograph also addresses their associated, local and worldwide socio-economic impacts. The understanding and modeling of these phenomena is critical to the development of timely worldwide strategies for the prediction of natural and anthropogenic extreme events, in order to mitigate their adverse consequences. This monograph is unique in as much as it is dedicated to recent theoretical, numerical and empirical developments that aim to improve: (i) the understanding, modeling and prediction of extreme events in the geosciences, and, (ii) the quantitative evaluation of their economic consequences. The emphasis is on coupled, integrative assessment of the physical phenomena and their socio-economic impacts. With its overarching theme, Extreme Events: Observations, Modeling and Economics will be relevant to and become an important tool for researchers and practitioners in the fields of hazard and risk analysis in general, as well as to those with a special interest in climate change, atmospheric and oceanic sciences, seismo-tectonics, hydrology, and space weather.
Volcanoes are essential elements in the delicate global balance of elemental forces that govern both the dynamic evolution of the Earth and the nature of Life itself. Without volcanic activity, life as we know it would not exist on our planet. Although beautiful to behold, volcanoes are also potentially destructive, and understanding their nature is critical to prevent major loss of life in the future. Richly illustrated with over 300 original color photographs and diagrams the book is written in an informal manner, with minimum use of jargon, and relies heavily on first-person, eye-witness accounts of eruptive activity at both "red" (effusive) and "grey" (explosive) volcanoes to illustrate the full spectrum of volcanic processes and their products. Decades of teaching in university classrooms and fieldwork on active volcanoes throughout the world have provided the authors with unique experiences that they have distilled into a highly readable textbook of lasting value. Questions for Thought, Study, and Discussion, Suggestions for Further Reading, and a comprehensive list of source references make this work a major resource for further study of volcanology. Volcanoes maintains three core foci: Global perspectives explain volcanoes in terms of their tectonic positions on Earth and their roles in earth history Environmental perspectives describe the essential role of volcanism in the moderation of terrestrial climate and atmosphere Humanitarian perspectives discuss the major influences of volcanoes on human societies. This latter is especially important as resource scarcities and environmental issues loom over our world, and as increasing numbers of people are threatened by volcanic hazards Readership Volcanologists, advanced undergraduate, and graduate students in earth science and related degree courses, and volcano enthusiasts worldwide.

This conference was prompted by the occurrence of 5 encounters between passenger jetliners with drifting clouds of volcanic ash from the 1989-90 eruptions of Redoubt Volcano in Alaska. Examines 5 principal areas, including: how volcanoes produce ash clouds, the damage and impacts resulting from ash-cloud encounters, communications procedures for mitigating the risks from volcanic ash, the meteorology and modeling of ash-cloud movement, and methods for detection and tracking of ash clouds. 60 technical presentations are included.
Climate change is one of the biggest challenges facing the modern world. The chemistry of the air within the framework of the climate system forms the main focus of this monograph. This problem-based approach to presenting global atmospheric processes begins with the chemical evolution of the climate system in order to evaluate the effects of changing air composition as well as possibilities for interference within these processes. Chemical interactions of the atmosphere with the biosphere and hydrosphere are treated in the sense of a multi-phase chemistry. From the perspective of a "chemical climatology" the book offers an approach to solving the problem of climate change through chemistry.
