In this rewritten second edition of his work Volcanoes (first published in 1969), Professor Ollier provides an account of volcanoes, vulcanism and associated landforms. He analyzes the effects of weathering and erosion on volcanoes and lava flows, and describes the course of landscape evolution in volcanic areas. Drawing on examples and research from all over the world, the author examines the distribution of volcanic activity with reference to contemporary debates about global tectonics. Professor Ollier also discusses the human response to volcanoes, describing methods of prediction and what should be done when a volcano erupts. This book is aimed at undergraduate students of geomorphology and physical geography.
