Natural Hazards: Earth’s Processes as Hazards, Disasters, and Catastrophes delves into the earth processes that directly impact human societies. Authored by Duane E. DeVecchio and Edward A. Keller, this fifth edition remains a key resource for university and college courses focused on natural hazards. Integrating principles from geology, hydrology, meteorology, climatology, oceanography, soil science, ecology, and solar system astronomy, the book offers an accessible exploration of hazardous events. Each chapter is structured to be manageable for students, starting with learning objectives and concluding with review questions and high-level critical thinking exercises. A new Concepts in Review section at the end of each chapter highlights key points, summaries, important visuals, and terms. Updated case studies and figures bring real-world examples into focus, enhancing understanding. This edition is designed to support instructors guiding non-science majors through a conceptual framework for understanding natural hazards and their societal impacts.
