In the next few hours, California coasts experience the effects of the massive tremors that ravaged the east coast of Russia.
Officials estimated the waves in Southern California were modest.
However, in the north, the waves can be increased. Officials in Northern California have urged people not to go to the beach, but have not issued evacuations.
Here’s what you’re looking for:
Wave size
Officials estimated that the waves in Southern California were modest in size and that if those predictions were to be brought about, the waves were unlikely to cause major problems. However, in the north, the waves can be increased.
The biggest impact is expected in Crescent City, Del Norte County, where waves of up to 4.8 feet are expected.
Waves up to 3.7 feet are predicted in Port San Luis, San Luis Obispo County. The rest of the California coast is to predict that they will see waves below 1.3 feet, with the waves in Los Angeles expected to be less than a foot.
timing
If the tsunami were to happen, it would hit Fort Bragg in Mendocino County at 11:50pm and Crescent City in Del Norte County at 11:55pm on Tuesday.
Then, early Wednesday mornings, potential waves arrive at Monterey at 12:15am, San Francisco at 12:40am, Los Angeles Port at 1:05am, Newport Beach at 1:10am, and Oceanside and La Jolla at 1:15am.
caveat
Where is the tsunami hazard zone in California?
Tsunami hazard zones can spread to Bayside and riverside areas relatively far from the Pacific coast.

When the tsunami hit in 2022, California experienced a relatively small effect. But at Santa Cruz Harbor, waves flooded the streets and parking lots, where cars floated like toy boats. Water was poured into the bathroom on land and the electric transformer. It caused an estimated $6 million in damages in Santa Cruz alone, officials later said.
In 2011, the tsunami of the devastating Japanese earthquake struck several California coastal areas, causing more than $100 million in damage to marinas and ports, state officials estimate. In Crescent City, residents reported that around 30 boats had been “smashed” at the port, and that the surge in water had caused many docks to be significantly damaged or destroyed.
One died after being swept into the ocean while taking photos of the tsunami.
In 2006, Crescent City residents were caught off guard by considerable seawater surges after the tsunami warning expired, causing port damage.
Most notably, the 1964 Alaska earthquake devastated the crescent city, washed away 29 city blocks and caused a devastating tsunami that killed at least 11 people. A series of night waves crashed coastal cities, destroying or damaging 91 homes and 172 businesses.
California officials also have records of the tsunamis that hit Northern California in 1960 and 1946, each of which killed at least one person. The 1946 tsunami was caused by an 8.6 magniture earthquake near Alaska, flooding parts of Half Moon Bay.
According to the US Geological Survey, the earliest records of the California tsunami include an event in which a major earthquake in the Santa Barbara area in 1812 “sweeping out many coastal villages and destroying ships at the port.”
Preparation
Find the tsunami hazard map for your area. If maps or signs are not available, state officials suggest that they reach an inland area 100 feet or two miles above sea level. “If you can’t get there before, go as high as possible. Every foot, inland or upward, can make a difference,” state officials say.
The National Weather Service operates two tsunami warning centres to send tsunami alerts with the aim of monitoring tsunamis and earthquakes that may cause them. To get official tsunami warning notifications, sign up for text message alerts from local governments, get a battery-equipped national marine and air management weather radio, or listen to TV, radio, or automatic phone announcements.

Authorities urged people not to go to the coast to see the tsunami, noting that they could not surf the tsunami.
According to the University of Hawaii, “we can’t surf the tsunami because the surfboard doesn’t have a face to grab the waves.” In 2022, San Francisco firefighters had to rescue experienced surfers from the incoming tsunami.
A California geological survey says the tsunami caused damage to California’s infrastructure, waterways and boats.
