Summary Table of Contents Author Biography

Volcanoes are a vital presence in our world, and play a key role in maintaining the human eco-environment through soil enrichment and atmospheric inputs. They are also hazardous features, whose eruptions have not only killed many hundreds of thousands of people in recorded history, but have also greatly influenced both the development of human culture and the evolution of human species. Volcanoes commonly form beautiful landscapes, and form the principal features of national parks all over the world, serving as magnets that attract millions of ... MOREvisitors each year. Hundreds of millions of other people live on or in the shadows of active volcanoes. Most of these people have only a shallow, passing interest in the volcanoes they see, but there is a certain large, enthusiastic cohort of these people whose fascination with volcanoes leads them travel to see volcanoes close-up, and to seek authoritative volcanological information.The study of volcanoes and volcanic activity is an essential component of all introductory geology courses. Although the typical exposure to volcanology is superficial in most introductory courses, advanced undergraduate courses and specialized graduate courses require authoritative textbooks on volcanology - either for reference, or as the backbone of focused courses and seminars. We believe our book would best serve college-level students poised to enter the earth sciences professionally, and will also serve as an important reference for interested lay readers and earth scientists in general. * Four color throughout with dozens of superb color photographs * Suitable for students with no mathematical background * End-chapter study questions for students

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.
