Welcome to the Natural Hazards Web site, which accompanies Physical Geography: The Global Environment, third edition, by H.J. de Blij, Peter O. Muller, and Richard S. Williams, Jr.

Earthquakes, volcanoes, tornadoes, hurricanes, and floods: all of these are dangerous, hazardous events that occur in the natural world as a result of physical processes. On this web site, you can discover the causes of these events and learn what people can do to mitigate the damaging effects of these natural hazards. Next, you’ll explore these topics further with the additional resources listed, then test your knowledge with the activities we've provided. The information presented on this site will allow you to expand upon the knowledge you’ve encountered in your Physical Geography textbook in an exciting, interactive way.
