New North Cascades maps Take a North Cascades field trip Lifeline Hazards Greater Seattle area Willamette Valley (in development)

New maps of the North Cascades New North Cascades geologic maps Take a North Cascades National Park region field trip Geologic story, virtual field trip, and more . . . Lifeline Hazards Lifelines and earthquake hazards in the greater Seattle area The Seattle area is earthquake country. Preliminary measurements show clear evidence that strain is slowly building toward the next earthquake. The greater Seattle area depends on highways, railroads, pipelines, ports, airports, communications, and the electrical power system to sustain its economic life. Many of these critical lifelines lie across the path of faults. This new map shows the relation of lifeline elements to selected earthquake hazards. The map is designed to give citizens, engineers, planners, and decision-makers an overview of lifelines and earthquake hazards in the greater Seattle area. Lifelines and earthquake hazards in the Willamette Valley Coming soon.
