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
