As a developer of geology and earth science college textbooks for major publishers, I've worked with a lot of excellent books. Patrick Abbott's Natural Disasters, second edition, is one of the most interesting, readable, informative, and engaging books available. It doesn't have all the four-color diagrams and photos, and doesn't need them. The book tells many fascinating stories that engage students (e.g., the Lisbon earthquake of 1755), relates these natural events to humanity, and offers outstanding short summaries of geologic phenomena and events (e.g., the K-T extinction). This is one of the few books I keep on my desk to illustrate geologic events and principles for friends and coworkers. Highly recommended!
