Tsunami advisory issued for California coast after 8.8 magnitude earthquake near Russia.
A massive magnitude 8.8 earthquake struck off the coast of Russia on Tuesday, sparking tsunami warnings — and evacuations — in Hawaii and alerts for other areas of the U.S. West Coast.
In a message posted on social media, President Donald Trump urged people to “STAY STRONG AND STAY SAFE” and to monitor updates on the tsunami.gov online dashboard.
A tsunami warning was issued for Northern California, from Cape Mendocino to the Oregon border. The rest of the California coast was under a Tsunami Advisory, and if a wave is generated, it’s expected to reach California at 11:50 p.m. and the Los Angeles area around 1 a.m. local time.
“Port Police and emergency officials are actively responding to tonight’s Tsunami Advisory. Residents and workers in and around the L.A. Harbor area are urged to stay alert, avoid the waterline, and follow official instructions,” said L.A. Mayor Karen Bass on X.
Further down the coast, the city of Huntington Beach is closing its pier and beaches out of an abundance of caution. Orange County officials announced that they’ve closed all Orange County Parks managed beaches.
In Hawaii, the National Weather Service called for “urgent action” to protect lives and property.
Officials there urged residents to leave beaches and evacuate low-lying areas for higher ground or to take shelter on at least the fourth floor of a building.
The first tsunami waves were forecast to reach Hawaii just after 7:15 p.m. local time — or 1:15 a.m. ET. Destructive tsunami waves are expected, according to Oahu Emergency Management.
All shores of the island are at risk because tsunami waves wrap around islands, according to the National Weather Service.
“The danger can continue for many hours after the initial wave as subsequent waves arrive. Tsunami heights cannot be predicted and the first wave may not be the largest,” the NWS said in an alert.
Sirens were set to go across the Hawaii islands 10 minutes after each hour for the next three hours as a part of a statewide warning system.
In an interview with ABC Honolulu affiliate KITV, Honolulu Mayor Rick Blangiardi urged residents to move to higher ground.
“We need people to stay calm but also to act accordingly. If you can get to higher ground if you’re in a low-lying area, please do that.” He urged caution on the roads amid “bumper-to-bumper traffic” during evacuations.
Tsunami alerts for U.S. West Coast — and elsewhere in the world
In the wake of the quake, a tsunami warning was also issued for part of Alaska’s Aleutian Islands and for Northern California, from Cape Mendocino — located about 200 miles north of California — to the Oregon border. The rest of the California coast as well as Oregon and Washington are under a tsunami advisory, while the threat is being evaluated.
The U.S. territories of Guam and American Samoa are also under a tsunami advisory, according to USGS.
The intense quake occurred about 85 miles off the east coast of Russia’s Kamchatka Peninsula with a depth of nearly 12 miles, according to the U.S. Geological Survey. It was one of the most powerful earthquakes ever recorded by the agency, which upgraded its magnitude from initial reports of 8.0 and 8.7.
Magnitude 6.3 and 6.9 aftershocks were also reported in the area, according to USGS.
An advisory was also issued for Japan’s Pacific Coast regions from Hokkaido to Kyushu.
Japan’s meteorological agency warned that a tsunami about 1 meter (3 feet) high is expected to reach Hokkaido in the north around 10:00 a.m., local time, with waves arriving later in the day along parts of eastern Honshu and Kyushu in the south.
People are warned to stay away from the coast and river mouths and not to approach the water to observe.
Ecuador and Chile are also under tsunami alerts, according to local officials.
A tsunami warning means that a tsunami that could cause widespread, dangerous flooding and powerful currents is expected. A tsunami watch means a distant earthquake has occurred and a tsunami is possible.
