Many popular volcano books have appeared over the last few years; for example, Vulcan's Fury by A. Scarth, Melting the Earth by H. Sigurdsson, and Volcanoes in Human History by J.Z. deBoer and D.T. Sanders. All of these books have their own qualities. Duffield's Chasing Lava-A Geologist's Adventures at the Hawaiian Volcano Observatory stands apart from that crowded field and is comparable to Out of the Crater by R.V. Fisher. The book presents a very personal view of volcanology, erupting volcanoes, and what it means to be part of a team that investigates them. The author mixes scientific observations with accounts of the grandeur of Hawaii, musings about his own personal life 30 years ago, and the pleasure that one derives from working in an organization like the Hawaiian Volcano Observatory (HVO) on a gorgeous tropical island. The book starts out with the history of the HVO and the accomplishments of T.A. Jaggar as scientist-in-charge. The author then gives accounts of his own work on Hawaii and introduces the reader to, among other topics, tilt measurements and laser reflector instruments. He discusses the search for fresh water on the island, and notes that the need for clean water ultimately may become one of the most pressing issues of this island world. He alternates between descriptions of geological features with great photographic close-ups of flowing lavas, and narrow escapes; and casually introduces fundamental geological perspectives in the process. Most geologists are familiar with Duffield's ideas about the shifting plates on the surface of Mauna Ulu lava lake as an analog of global plate movements. I was not aware of his experiments with bastnaesite-doping of the magma to add a La-rich tracer to the magma to track its lateral flow, but in this book readers learn about both.
