What do I do during a tsunami?
Evacuate the area by foot and get to higher ground. Don’t get in your car and try to drive away from the hazardous area — evacuating by car could create a traffic jam.
How fast do tsunamis move?
Waves are generated and move out in all directions across the ocean, some traveling as fast as 600 mph. As waves enter shallower water, they compress, their speed slows, and they build in height, pushing water ashore. What we experience on land wouldn’t be the common misperception of a massive wave that a surfer could ride all the way to the 405 Freeway. It’s more like a surge of water that rushes inland, threatening anyone and anything in its path. Tsunamis aren’t just a single wave, either — they can last for hours and cause devastation miles inland, as Japan experienced in 2011.
Where do tsunamis come from?
Distant-source tsunamis typically come from Japan, Chile or Alaska. Graehl said the worst-case scenario for Southern California is a tsunami generated from the eastern Aleutian Islands in Alaska. It would take five to six hours to arrive — providing some time for notification and evacuation. When it did arrive, though, it could produce more than one significantly large surge.
Where is the Cascadia Subduction Zone fault?
Graehl said Northern California could experience a significant local tsunami event generated from a major earthquake on the Cascadia Subduction Zone fault — a 700-mile undersea boundary where tectonic plates are colliding — that stretches from Northern Vancouver Island to California’s Cape Mendocino. This type of event could cause at least six minutes of shaking, giving people 10 minutes before surges of water of up to 50 feet high hit Crescent City, which has the highest tsunami risk in the state.
