Petropavlovsk-Kamchatsky / Tokyo / Honolulu, July 30, 2025: A powerful 8.8 magnitude earthquake struck off the coast of Russia’s Far Eastern Kamchatka Peninsula early Wednesday, unleashing tsunami waves of up to five metres (16 feet) and prompting widespread evacuation orders across the Pacific, including in Japan, Hawaii, and parts of North and South America.
The shallow quake, which occurred at a depth of 19.3 km (12 miles), was centred approximately 119 km (74 miles) east-southeast of the city of Petropavlovsk-Kamchatsky, home to around 165,000 people. Russian authorities described it as the strongest earthquake in the region since 1952.
Tremors damaged buildings and injured several people in Kamchatka, with dramatic video footage showing medical personnel continuing surgery as the operating room shook. “It felt like the walls could collapse any moment,” said Yaroslav, 25, a resident of Petropavlovsk-Kamchatsky, who rushed out of his building as the quake lasted for nearly three minutes.
Tsunami waves slammed into coastal parts of Kamchatka and the nearby Kuril Islands, with water sweeping vessels from moorings and partially submerging ports and processing plants in the town of Severo-Kurilsk. Drone footage revealed entire shorelines inundated, with industrial facilities surrounded by water cascading back into the sea.
Kamchatka Governor Vladimir Solodov called it “the most serious and strongest earthquake in decades,” while Russia’s emergency services reported damage to a kindergarten and several buildings. However, no fatalities were confirmed and most infrastructure withstood the quake. Dozens sought medical attention, regional health minister Oleg Melnikov said.
In Hawaii, tsunami waves of up to 1.7 metres (5.5 feet) reached the coast, triggering temporary evacuations and disrupting airport operations in Honolulu and Maui. The U.S. Coast Guard ordered ships to leave ports, and residents were advised to move to higher ground. The Pacific Tsunami Warning Center later downgraded the threat, stating that no major tsunami was expected.
Tsunami effects were felt as far as California and British Columbia, where waves under half a metre were observed.
Japan, still haunted by the 2011 Fukushima disaster, swiftly issued evacuation orders along its eastern coast. Alarms blared across Pacific-facing towns, with authorities ordering tens of thousands to move to safer ground. Footage from NHK showed residents sheltering on rooftops in Hokkaido and fishing boats heading out to sea to avoid damage.
Tragically, a 58-year-old woman died in Mie Prefecture when her car plunged off a cliff while she was attempting to evacuate. Nissan Motors temporarily suspended operations at some facilities as a precaution, while Tokyo Electric Power (TEPCO) evacuated workers from the Fukushima Daiichi nuclear plant. Authorities reported no irregularities at nuclear facilities.
Japan’s Meteorological Agency recorded three tsunami waves, the largest measuring 1.3 metres (4.3 feet). Chief Cabinet Secretary Yoshimasa Hayashi said no injuries or major damage had been reported in Japan.
The U.S. Tsunami Warning System said waves of more than three metres remained possible along parts of Russia, northern Hawaiian islands, and Ecuador, while one to three metre waves could still affect Japan, Chile, and the Solomon Islands.
In Severo-Kurilsk, tsunami waves exceeding five metres battered the coastline, prompting local mayor Alexander Ovsyannikov to advise residents to inspect homes for structural damage and avoid using gas heating until safety checks were conducted.
Kamchatka lies on the volatile Pacific Ring of Fire — an arc of seismic activity prone to frequent earthquakes and volcanic eruptions. Danila Chebrov, head of Kamchatka’s Geophysical Service, said aftershocks were ongoing but ruled out stronger immediate quakes. “The shaking intensity was not as high as one might expect from such a magnitude,” he noted, adding that the situation was under control.
