It is more than 40 years since the appearance of A. Rittmann’s Volcanoes and their Activity, translated from his 2nd, German edition of Vulkane und ihre Tätigkeit by E.A. Vincent. A somewhat similar process has taken place with the publication of H.-U. Schmincke’s Volcanism but this time the author himself has translated the 2nd edition (2000) of his original 1986 German textbook. The English edition is updated and in part rewritten to take account of recent important eruptions and research. Further figures have been added to what was already an impressively well illustrated book.
