The impact of volcanic eruptions on the Earth's environment has been the source of many a debate and the cause of extensive research activities by leading academics worldwide. The new edition of Peter Francis's Volcanoes preserves the particular strengths of the orignal in its accessibility, immense clarity, engaging humour and excellent illustrations. The book updates the original by reflecting on new research findings and new eruptions (such as that on Montserrat) as well as including a new chapter on volcanic hazards, which looks at the complex and scientific and sociological issues surrounding risk mitigation. In updating the planetary perspective of the book new co-author Clive Oppenheimer provides us with an insight into studies of Mars and Jupiter. The book is designed primarily for undergraduate students across a range of disciplines including geology, Earth sciences, geography, environmental sciences and planetary sciences, yet, is an equally valuable source for volcanologists, senior scientists in other disciplines and scientifically-trained volcano enthusiasts.
