Explains how maps can tell us a lot about where we can anticipate certain hazards, but also how maps can be dangerously misleading. The text considers that although it is important to predict and prepare for catastrophic natural hazards, more subtle and persistent phenomena such as pollution and crime also pose serious dangers that we have to cope with on a daily basis. Hazard-zone maps, the text explains, highlight these more insidious hazards and raise awareness about them among planners, local officials and the public. With the help of many maps illustrating examples from all corners of the United States, the text demonstrates how hazard mapping reflects not just scientific understanding of hazards but also perceptions of risk and how risk can be reduced.
