Pacific Northwest Geologic Mapping and Urban Hazards

Lifeline Hazard Maps

Urban areas depend on highways, railroads, pipelines, ports, airports, communications, and the electrical power system to sustain economic life. In parts of the Pacific Northwest, many of these critical lifelines lie across the path of faults. These maps show the relation of lifeline elements to selected earthquake hazards.
