There is no escaping geology on the West Coast of the US. Earthquakes shake California continually. Volcanoes loom over northern California, Oregon, and Washington. Each of these hazards marks a different kind of plate boundary--a transform fault to the south, a subduction zone up north. This map shows the western US, along with all of the known major fault lines and zones.
The 1995 "Living on the Edge" map features:• Active faults, faults not considered to be active, subduction zones
• Relief map of the western US, showing locations of faults, earthquakes, and volcanoes
• Volcanoes active in the past 10,000 years
• Earthquake epicenters, and earthquake magnitudes 1964-1994
• An inset explaining how the Transform Fault shaping much of the current California was formed
Coverage Area: Western US, California, Oregon, Washington, Baja California
