Deep earthquakes (earthquakes with origins deeper than 60 km) are of scientific importance and account for approximately one-quarter of all earthquakes. They are occasionally very large and damaging yet provide much of the data that constrain our knowledge of Earth structure and dynamics. This book opens with an explanation of what deep earthquakes are, their significance to science and how they were first discovered. Later chapters provide a description of deep earthquake distribution and clustering in both time and space; a review of observations about source properties; and a discussion of theories for the origin of deep earthquakes. The book concludes with a comprehensive literature review of terrestrial and lunar deep seismicity. Deep Earthquakes presents a comprehensive, topical, historical, and geographical summary of deep earthquakes and related phenomena. It will be of considerable interest to researchers and graduate students in the fields of earthquake seismology and deep Earth structure.

Review of the hardback:'A feature which I enjoyed particularly is … [the] use of numerous text boxes to provide detail for points of special importance. … This book is considerably more than yet another text in earthquake seismology: it also emphasises the human element as science is being done. For example, Frohlich takes pains to narrate how the thinking of some of the leading players evolved over time.'

Review of the hardback:'A labour of love by a dedicated researcher with a passion for the topic, Deep Earthquakes by Cliff Frohlich is unusual in its combination of breadth, depth and tone. … The book succeeds in offering results and explanations that are topical and, though occasionally technical, still accessible. And I know of no other text devoted to deep earthquakes, or even one that treats them in depth. … Overall, Deep Earthquakes is quite an accomplishment. Bottom line: If, like many geophysicists, you are curious about this mysterious phenomenon, check out Frohlich's book. It will most likely answer some questions and raise many others.'

Review of the hardback:'The controversial issues are presented clearly and objectively. …Many interesting observations can be found … a great resource for any scientist planning a project focused on any of these regions who wishes to obtain a quick overview over previous research into the local deep earthquakes. … the book makes a good read for any geophysicists with some interest in seismology, and it is certainly pitched at a level entirely accessible to advanced undergraduate students.'

Review of the hardback:'… easy to read, whether one is a seismological beginner, a graduate student or researcher … Even the world's leading seismologists may profit from the book since it systematises prevalent findings and provides an extensive list of references. Collecting this list must have been a titanic work just by itself. … presents comprehensive information on the phenomena, state-of-the-art 2006 … worth its price.'
