Volcano Deformation (eBook, PDF)

New Geodetic Monitoring Techniques

• Format: PDF

Produktbeschreibung

Volcanic Deformation is the first book devoted to volcano geodesy, a specialisation of the still-young science of volcanology. It forms a part of the whole catalogue of methods used to monitor a restless or an erupting volcano, and demonstrates how risk from hazardous eruptions can be reduced.

With contributions from some of the most experienced and knowledgeable experts in the field, the book desbribes the state-of-the-art techniques used by volcanologists to successfully predict volcanic eruptions. With chapters on GPS and synthetic aperture radar interferometry, Volcanic Deformation covers both the "classical" and emerging methodologies, and looks at the future challenges faced by scientists when predicting volcanic eruptions.

Volcanic Deformation

• is an up-to-date, comprehensive treatment of volcanic geodesy and its applications;
• describes how volcanic geodesy complements other volcano monitoring approaches and tools;
• gives an extensive treatment of the key lessons volcanologists have learned at well-monitored deforming volcanoes.

Rezensionen

From the reviews:

"This monumental, first-of-a-kind, up-to-date book on volcano geodesy compiled by Dzurisin ... fills an important gap in the rapidly expanding literature discussing the young science of Volcanology. ... The outstanding list of references offers more than 400 citations; the extra material contains all the book's figures plus an expanded version of analytical source models. ... The chapter authors are eminently qualified, and their book is a marvelous contribution to the highly complex, important, and challenging profession of volcano monitoring. Summing Up: Highly recommended." (T. L. T. Grose, CHOICE, Vol. 44 (11), July, 2007)
