Volcanoes have an endless fascination. Their eruptions are a regular reminder of the power of nature and our vulnerability to this raw geological phenomenon, however volcanic activity, and its plumbing from beneath, is an essential element of the forces that shaped and constantly reshape our planet. Dougal Jerram answers the questions: What are volcanoes? What other volcanic activity is there? How do volcanoes relate to plate tectonics and the movement of continents? What are eruptions and why do they occur? How have volcanoes affected the earths climate? Can we predict eruptions? He also describes the most notable eruptions in history and their effect. Copiously illustrated throughout Introducing Volcanology is a concise and accessible introduction to the science of hot rocks for those with an adult curiosity and for those contemplating a course of formal study. As with sister volumes, technical terms are kept to a minimum and a glossary is provided covering the whole subject from ash to zeolites.

This book tells you everything you need to know about a trip to the planet's core, with the proposed journey to be made using an ingenious Centre-Pod drilling vehicle. Starting with your first entry through the earth's mantle, at a boundary in the tectonic plates, you'll travel through the geological layers to reach the twin layers of the earth's core. Activities for your trip include exploring a volcano, hunting for diamonds under the cratons, discovering what it's like at the hypocenter of an earthquake, and riding up a mantle plume on your return journey. Also included are lists of "What Not To Miss At The Earth's Core," "Top Ten Favourite Excursions," and "The Centre of the Earth in Popular Culture."

Volcanoes are intimately tied to the history of humanity, they help forge the Earths crust and atmosphere, and they are very much an active feature of today. The archaeology of most ancient civilizations of Europe preserves the imprint of spectacular and volcanic phenomena while, in modern times life is still affected by large eruptions from Europes active volcanic systems. The eruption of Santorini, some 3600 years ago in the Aegean, probably inspired the Greek fables of Atlantis; the eruptions of Etna on Sicily are the origin of the forges of Cyclops and other myths; and the regular eruptions from Stromboli earned its Roman name, the Lighthouse of the Mediterranean. Eruptions in Iceland over the past few centuries have shaped more recent European history and highlight the dramatic effects that distant large eruptions can have on our modern way of living. This thoroughly revised and updated edition reflects modern research and is now illustrated in colour throughout. It presents the volcanoes of Europe, as they are today and tells how they have shaped our past. The volcanic systems of the Mediterranean basin, the Atlantic, and of mainland Europe are introduced and described in clear prose with a minimum of technical jargon. Some of Europes ancient volcanic systems is also described as these have been fundamental in shaping the science of volcanology. The origins, history and development of Europes volcanoes is presented against a background of their environmental aspects and contemporary activity. Special attention is given to the impact of volcanoes on the people who live on or around them. The book is written for student, amateur and professional earth scientists alike. To help guide the reader, a glossary of volcanic terms is included together with a vocabulary of volcanic terms used in European languages.
