For centuries humans have puzzled over volcanoes. Why do volcanoes erupt? How do they work? The author of this text, a volcanologist, traces the history of ideas about volcanoes, a history spanning more than 2000 years - from the notions of the ancient Greeks to the more scientific, experimentally based theories of today. Underlying his stories is an endeavour to answer the question: How do rocks melt in the Earth?

Summary: "Dr. Harold Sigurdsson's new book Melting The Earth is a wonderful journey through time as he traces the history of man's fear and love of volcanic eruptions. I can't think of a better guide on this epic journey." --Robert D. Ballard, Ph.D., President, Institute for Exploration"An attractive and readable account of the history of ideas about volcanoes."--Nature"Evolving philosophical and theological debate, tempered by a growing body of scientific knowledge, flavors the beautifully written text. The author, born and raised in volcanic Iceland and an international volcanologist, wrote this rich history of his science for deeper appreciation and perception into the role of human interaction with a mighty natural force. Historians and scientists will thoroughly enjoy this book."--Choice"In Melting the Earth, Haraldur Sigurdsson draws on his Icelandic heritage to show how man has long been fascinated by volcanoes, particularly in parts of the world where they are a dynamic presence and potential cause of disaster. Many ancient cultures have extensive volcano myths whose origins may be even older. After the Dark Ages and with exploration of the globe and skies, a vast amount of new information became available, and efforts to explainhow the world works developed at an ever-increasing pace. A major conceptual advance was considering that the earth could have a vast amount of primordial heat. The discovery of radioactivity in the current century provided an adequate heat source, and detailed geophysical observations led to platetectonics. Sigurdsson emphasizes ideas that prevailed at each stage of history, and thus spends as much time on ideas eventually discarded as those still incorporated in the modern view." - William Green, The Leading Edge, April 2000"Haraldur Sigurdsson is a professor in the Graduate School of Oceanography at the University of Rhode Island. As a practicing volcanologist and native of Iceland, where volcanoes are frequently active, Sigurdsson chronicles humankind's attempt to understand volcanic eruptions and provides a fascinating look at how our conception of volcanoes has changed as knowledge of the earth's internal processes has deepened over the centuries. Drawing liberally fromclassical sources and firsthand accounts, this chronicle is not only a colorful history of volcanology, but also an engrossing chapter in the development of scientific thought." - California Geology , May 2000.
