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.
