Q: How will I know if an evacuation warning is issued for Del Norte County?
If officials receive notice that a tsunami is possible you will hear a steady 3-minute siren blast.
Police and fire vehicles with public address systems will patrol neighborhoods in the run-up zone to warn residents. If time permits, door-to-door notifications will occur.Turn on to local radio stations to receive specific instructions.
But a siren isn't the only warning: If you feel an earthquake in Crescent City, it's because the Cascadia Subduction Zone has moved. The area lies offshore of Cape Mendocino and is located 35-70 miles from Crescent City. When it moves, know that the ocean will, too.
