Community exposure to tsunami hazards in California

Inspired by recent catastrophic tsunamis, the authors have graphically presented the results of their research through color maps and photographs depicting the 94 cities in 20 counties located in tsunami-prone areas up and down the California coast. Charts and data tables classify the at-risk populations as permanent residents, estimated visitors, and commuting employees. As a benchmark for measuring the danger level to individual communities, the authors have developed a composite index number, derived from the amount of developed land and the number of people and businesses.
