The recent advances in the field of volcanology are elucidated in this profound book. This book provides a geologic-petrologic explanation of prominent volcanic fields across the world which is less discussed in international literature on volcanology. It also provides discourses and inferences about the outcomes associated with geophysical methods. It emphasizes on numerous situations reflecting large-scale volcanisms on Earth, related both with active or intra-plate margins. Several huge volcanic networks of Eastern countries have been discussed in this book, inclusive of those in Mongolia, Siberian Russia, and Japan. Descriptive information on the European volcanic province of the Pannonia basin and Central-Southern Spain has also been provided. Areas of the southern hemisphere of Polynesia and Antarctica have also been covered in this book. It is a significantly useful source of information as a guide for people interested in visiting or hold curiosity in knowing about the major characteristics of the above volcanic areas, with some of them being remote and highly unreachable.
