“This 363-page book is well written, self-contained and provides all up to date information for anyone interested in the volcanic activity over the North Pacific, and a must have for everyone interested in volcanology and remote sensing. It is full of colored, high-quality images that help the reader to conceive the presented material which also makes the book more appealing.” (Alexandra Karamitrou, Pure and Applied Geophysics, Vol. 174, 2017)
