A massive 8.7 earthquake struck off Russia’s Kamchatka Peninsula early Wednesday, triggering tsunami warnings along the Pacific Rim. Emergency protocols were in place in Japan, Russia, Hawaii, and the American West Coast, including California, where wave arrival is forecast for 12:15 AM PDT.
The earthquake hit at 8:25 AM local time in Russia (11:25 PM GMT Tuesday), about 250 km from Hokkaido, Japan, according to Japan’s Meteorological Agency. The US Geological Survey (USGS) later upgraded the quake’s magnitude from 8.0 to 8.7, located at a shallow depth of 19.3 km, a key factor in tsunami formation.
Japan rapidly upgraded its tsunami warning to an official alert, predicting waves of up to 3 meters that were expected to hit northern coastal regions in 30 minutes.
A 3–4 meter (10–13 feet) wave was already seen in Kamchatka, the emergency minister Sergei Lebedev said. Severo-Kurilsk town was instructed to evacuate, while people in Petropavlovsk-Kamchatsky reported scenes of chaos — blackouts, telephone outages, and people running barefoot.
Japan’s government deployed an emergency task force. Experts say that even faraway quakes can produce long-distance tsunamis traveling towards Japan, a country highly susceptible to such events as it sits on the Pacific Ring of Fire.
The Pacific Tsunami Warning Center sent out warnings for Hawaii, forecasting destructive waves by 7 PM local time. Coastal dwellers have been asked to immediately take protective action.
On the mainland U.S., a tsunami watch is in effect from California to Oregon, Washington, and most of Alaska, including the Aleutian Islands and the panhandle area.
Waves as high as 4 metres are expected to strike the Marquesas Islands in French Polynesia early Wednesday morning, AFP reports, citing local officials.
According to a statement from the High Commission of the French Republic in French Polynesia, tsunami waves between 1.10 and 4 metres are anticipated to hit Nuku Hiva, part of the Marquesas archipelago, starting around 1 a.m. local time (11:00 GMT). The nearby islands of Ua Huka and Hiva Oa are also likely to be impacted.
Following the powerful earthquake off Russia’s coast, Hawaii Emergency Management Agency administrator James Barros clarified that a tsunami is more than just a single wave. “It’s a series of powerful waves that can last for hours,” he told AP. “They travel across the ocean at jet-like speeds in deep waters, but as they near shore, they slow down and pile up — increasing the risk of coastal inundation.” While Hawaii experienced tsunami activity earlier today, officials have now downgraded warnings to advisories. Evacuated areas have been declared safe for residents to return. googletag.cmd.push(function() { googletag.display('div-gpt-ad-1752148780792-0'); }); ...
As of July 29, 2025, 10 PM local time, the Hawaii Department of Transportation issued a public update on airport operations following the tsunami triggered by a massive quake near Russia’s Kamchatka Peninsula. Authorities continue to urge residents not to return to tsunami evacuation zones until officials declare it safe to do so. Hilo International Airport: Evacuation gates remain closed, but preparations are underway to resume runway operations for flights scheduled on Wednesday. Kahului Airport (OGG): All flights have been cancelled. Passengers are currently sheltering inside the terminal and will undergo rescreening before boarding once operations resume in the morning.

Tsunami waves generated by the powerful earthquake off Russia’s Kamchatka Peninsula have now reached California’s coast, the National Weather Service (NWS) confirmed. Tide gauges detected the waves at Arena Cove, with the tsunami continuing its path southward along the shoreline. Earlier, residents across Hawaii were urged to evacuate to higher ground or seek shelter on the fourth floor or higher of sturdy buildings. The U.S. Coast Guard (USCG) also directed all vessels to leave harbors immediately as the tsunami neared the islands. “Take Action! Destructive tsunami waves expected,” warned the Honolulu Department of Emergency Management in an urgent alert posted on X...
A powerful 8.8-magnitude earthquake off Russia’s Kamchatka Peninsula on Wednesday has revived interest in a decades-old manga prediction. The quake, which triggered tsunami waves toward Japan’s Hokkaido and Russia’s Kuril Islands, comes just weeks after the date foretold in Japanese artist Ryo Tatsuki’s 1999 manga The Future I Saw. Tatsuki had predicted a major catastrophe would strike southern Japan on July 5, 2025. Though that date passed without incident, the massive quake and tsunami occurring just 25 days later have sparked online debate. Social media users are calling the timing “eerily close,” with one post on X noting, “Not the exact date,...
