The impact of volcanic eruptions on the Earth`s environment has been the source of many a debate & 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 & excellent illustrations. The book updates the original by reflecting on new research findings & new eruptions (such as that on Montserrat) as well as including a new chapter on volcanic hazards, which looks at the complex & scientific & 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 & Jupiter. The book is designed primarily for undergraduate students across a range of disciplines including geology, Earth sciences, geography, environmental sciences & planetary sciences, yet, is an equally valuable source for volcanologists, senior scientists in other disciplines & scientifically-trained volcano enthusiasts.
