After a major earthquake off the coast of eastern Russia, a tsunami advisory was issued on the west coast, including California.
Here’s what you need to know to prepare:
guidance
For California, Oregon and Washington (area of the Tsunami Advisory Area), the public was encouraged to take action and prepare to issue warnings about details.
Where is the tsunami hazard zone in California?
Tsunami hazard zones can spread to Bayside and riverside areas relatively far from the Pacific coast.

timing
The National Tsunami Warning Center said if the tsunami comes into effect, they will arrive in Monterey at 12:40am on Tuesday at 11:50pm in Crescent City, Del Norte County, at 11:55pm on Wednesday at 12:15am in San Francisco, at 12:40am in San Francisco, at 1:05am in Port of Los Angeles.
The first wave of the tsunami will crash into the Oregon coast at 11:40pm on Tuesday, Washington State, early at 11:35pm.
Basics
Evacuate the area on foot and arrive at the highlands. Don’t try to get in your car and leave the dangerous area. Evacuation by car can cause traffic jams. If you evacuate from a coastal area, leave until authorities allow you to return. Tsunamis move faster than a person can run. Don’t try to surf the tsunami. Normal waves flow in circles without flooding higher areas. Tsunami waves are unpredictable and overflow the land like a wall of water.
How to prepare for a tsunami
Get local tsunami evacuation maps. The California Department of Conservation released an updated interactive hazard map this year. This is a tool to help you plan safe evacuation routes. The new map contains a function that allows users to look at the address and check if the location is in the specified tsunami hazard zone (highlighted in yellow). Find a specific map in Conservation.ca.gov/cgs/tsunami/maps.practice.
The basics of the tsunami
There are two types of tsunami. Local sauce tsunami and remote sauce tsunami. Russia’s Tuesday trembling was a distant sauce event.
Distant source tsunamis are generated by earthquakes from distant sources. Depending on how you arrive here, it may take between 5-13 hours to arrive here. In that case, there is time to issue warnings and people evacuate.
Remote tsunamis in Southern California usually come from Japan, Chile or Alaska. According to a California geological survey, the worst-case scenario is a tsunami generated from the eastern Aleutian Islands of Alaska. It takes 5-6 hours to arrive. Provides notifications and time for evacuation. However, when it arrives, it can produce multiple significantly larger surges.
Local sauce tsunamis, or near field tsunamis, can be produced by sudden movements of offshore faults or underwater landslides. This type of tsunami is generated from nearby sources and can arrive in a few minutes.
