One of a series of general interest publications on science topics, the booklet provides those interested in earthquakes with an introduction to the subject. Following a section presenting an historical look at the world's major earthquakes, the booklet discusses earthquake-prone geographic areas, the nature and workings of earthquakes, earthquake generated seawaves (tsunamis) and landslides, and the measurement and prediction of earthquakes. The text is accompanied by numerous photographs illustrating the destructive effects of earthquakes, maps showing major earthquake zones, and diagrams clarifying internal processes involved in earthquake formation.
