Russia Earthquake, Pacific Tsunami HIGHLIGHTS: What Happened After 8.8 Magnitude Quake Struck Kamchatka Peninsula

A massive 8.8-magnitude earthquake off Russia’s remote Kamchatka Peninsula triggered tsunami waves across the Pacific, affecting California, Hawaii, and Japan. The quake, among the strongest ever recorded, caused no reported casualties, according to the Kremlin. A 1.09m (3.6ft) wave was recorded in Crescent City, California, with wave activity continuing along the coast.

Tsunami warnings have been downgraded in Russia, Hawaii, the Philippines, and Japan, though advisories remain in place. French Polynesia issued a warning for a 4m wave expected to hit Nuku Hiva after 01:00 local time. In Japan, sirens woke thousands along the Pacific coast. A tourist in Hawaii described the experience as "super nerve-wracking," while a Maui resident planned to sleep in a truck for safety.

Experts suggest the quake may be linked to a disappearing tectonic plate, a rare geological event capable of triggering powerful tsunamis.

Several island nations across the South Pacific have downgraded or cancelled their tsunami alerts following earlier warnings triggered by seismic activity.

Tonga announced that its tsunami alert has been officially cancelled, stating that “the potential threat to all island groups has passed.” Authorities confirmed that the current threat level has been assessed as “low.”

In Fiji, the government declared an "all clear," confirming that its tsunami watch advisory has also been lifted. “Communities may now resume normal activities,” officials said, while still urging the public to “remain alert” and continue monitoring official updates.

The Cook Islands likewise called off its tsunami advisory, stating that there is “no longer a tsunami threat” and adding that “no significant impacts have been reported” across the islands.

However, Samoa remains cautious. The country’s Disaster Management Office said on social media that its tsunami watch is still active. 

The Klyuchevskoy volcano on the Kamchatka peninsula in Russia’s far east has started erupting after Wednesday’s powerful earthquake in the Pacific, Russian state news agency RIA reported, according to Reuters.

The massive quake struck on Wednesday morning in Russia, generating a tsunami of up to 4 metres (13ft) on the country’s east coast, damaging buildings and prompting evacuation warnings in the region and across most of Japan’s east coast, officials said.

The Japanese meteorological agency has removed all tsunami warnings, downgrading them to advisories.

Now, the whole of Japan has either tsunami advisories or forecasts in place.

Initial reports indicate there has been "no safety impact for nuclear power plants along the Pacific coast," the UN's nuclear watchdog says.

The International Atomic Energy Agency says it is in contact with Japanese national authorities about the earthquake and resulting tsunami.

Authorities were on high alert due to the earthquake, with workers at the

Authorities in Russia's far eastern Kamchatka peninsula said Wednesday a tsunami warning had been lifted, more than 11 hours after an 8.8 magnitude earthquake near the region's coast prompted evacuations.

"Dear residents and visitors to the Kamchatka region, our colleagues from the State Emergency Situations Ministry have lifted the tsunami alert," the region's emergencies minister Sergei Lebedev said on social media.

The Kremlin on Wednesday said there had been no casualties and all warning systems had worked properly as tsunami waves wreaked havoc in Russia, carrying buildings and debris into the sea after a massive earthquake.

A tsunami warning has been issued for the Marquesas Islands in French Polynesia, with local authorities warning waves between 1.1 (3.6ft) and 2.2 metres (7.2ft) are expected in the coming hours.

The waves are expected to hit the islands of Ua Huka, Nuku Hiva, and Hiva Oa, authorities say, urging people in the area to evacuate to high-rise or refuge areas.

There is no need for evacuation for the rest of French Polynesia, though people are urged to avoid coastlines, beaches and river mouths.

The Japan Meteorological Agency has downgraded tsunami warnings in several areas to advisories. However, warnings are still in place for parts of Hokkaido and the Tohoku region. Authorities urge people to remain cautious until all alerts are fully lifted.

Waves have reached the US west coast, where waves in Crescent City, northern California, have been recorded now at 3.6ft (1.09m), according to the National Tsunami Warning Center.

A warning remains in place from Cape Mendocino to the border with Oregon. In Arena Cove, the waves have nearly doubled in height from 1.6ft (0.48m) to 3ft (0.9m) in the latest update.

The US National Weather Service uses a four-tier tsunami alert system:

Warning:

The tsunami warning covering Hawaii has been downgraded to an advisory level, the Pacific Tsunami Warning Center says,

This means there is the potential of strong waves, minor flooding and strong currents, but that a major tsunami is not expected to hit. Those evacuated may return home, Hawaii Emergency Management Agency director Stephen Logan says.

People are advised to drive slow and be safe, while watching for flooding in some areas.

A tsunami advisory has been issued for most coastal areas of British Columbia, Canada's most western province.

Residents are advised to avoid the ocean, follow official instructions and and wait for the all clear.

The tsunami has reached the coast of California, according to the US National Weather Service.

It's showing up in Arena Cove and Monterey in the north of the state, making its way further down, the service adds.

The warning comes from the US's National Oceanic and Atmospheric Administration (NOAA).

After the massive 8.8 earthquake near Russia’s Kamchatka, global tsunami alerts echo fears from the 2004 Indian Ocean tsunami. Nearly at least 230,000 lives were lost then reminding the world of nature’s immense power and urgency of preparedness.

Colombia ordered residents to evacuate beaches and coastal areas along the Pacific on Wednesday following a tsunami alert triggered by the 8.8-magnitude earthquake off Russia's eastern coast, authorities said.

"Tsunami alert for Choco and Narino," the National Unit for Disaster Risk Management posted on X early Wednesday, referring to two Pacific regions, adding: "Preventive evacuation of beaches and low-lying coastal areas is recommended."

The agency said it expected “strong and unusual currents and unpredictable surges at the shore” after the Russian earthquake. A warning said:

“People in or near the sea in the following areas should move out of the water, off beaches and shore areas and away from harbours, marinas, rivers and estuaries.”

People on boats, live-aboards and in marinas should move onto the shore, the warning said, adding that people should not go to the coast to watch for any waves coming in.

Shanghai has evacuated almost 283,000 people as Typhoon Co-May approaches the city, bringing lashing rains and high winds, state media reported Wednesday.

"From last night to 10:00 am today, 282,800 people have been evacuated and relocated, basically achieving the goal of evacuating all those who needed to be evacuated," state broadcaster CCTV reported.

At Oahu's Haleiwa Harbour, Hawaii officials saw water recede nearly 30 feet, a clear tsunami warning sign. Boats were left stranded on rocks and sand. “That gave us pause,” said Governor Josh Green. The dramatic ocean pullback alarmed authorities, who are closely monitoring wave activity and urging caution across Hawaii’s most populated island.

Hawaii's Kahului Maui gauge has recorded a tsunami amplitude of 4 feet relative to normal sea level. Meanwhile, Hawaii governor Josh Green in a press conference said, "We expect it to be two to three hours at least until we can call all clear."

Two stations in Hawaii now report 4-ft tsunami waves, per National Weather Service. Hawaii governor Josh Green says airports have not yet been impacted by waves.

The massive 8.8 earthquake near Russia's Kamchatka coast, was the strongest since 1952. It has triggered tsunami warnings across the Pacific and raised fears of aftershocks.
