Earthquakes shake California continually while volcanoes loom over northern California, Oregon, and Washington. These different hazards are caused by different kinds of plate boundaries—a transform fault to the south, and a subduction zone to the north.

This map shows:

• Active faults, faults not considered to be active, subduction zones
• Relief map of the western U.S., showing locations of faults, earthquakes, and volcanoes
• Volcanoes active in the past 10,000 years
• Earthquake epicenters, and earthquake magnitudes for 1964-1994
• An inset explaining how California’s transform fault was formed

This version is laminated—featuring a "write and wipe" surface and durable plastic covering. Please note: Allow 1-2 weeks for delivery.
