An 8.8-magnitude earthquake struck off the eastern coast of Russia early Wednesday, generating multiple tsunamis in the northern Pacific. Authorities from Hawaii to New Zealand quickly issued tsunami warnings as this quake marks the strongest seismic event since the 2011 disaster that caused meltdowns at a nuclear power plant in Japan.
The powerful earthquake hit Russia’s Far East at 8:25 AM Japan time, registering a preliminary magnitude of 8.0, which the US Geological Survey later updated to 8.8. The quake occurred at a depth of 20.7 kilometers, approximately 119 kilometers east-southeast of Petropavlovsk-Kamchatsky, a city with a population of 180,000.
Tsunami warning sirens blared in Honolulu, prompting residents to move to higher ground, with the Japanese Meteorological Agency reported a tsunami measuring 40 centimeters in Tokachi, located on Hokkaido’s southern coast.
Damage and Evacuations in Russia
The Kamchatka Peninsula, closest to the quake’s epicenter, experienced damage and evacuations as local governor Valery Limarenko confirmed that the first tsunami wave hit Severo-Kurilsk, the main settlement on Russia’s Kuril Islands. Fortunately, residents remained safe and stayed on high ground until the threat of additional waves subsided.
The Pacific Tsunami Warning Center warned that the quake-generated tsunami could cause damage along all Hawaiian coastlines. The advisory urged immediate action to protect lives and property, with the first waves expected around 7 PM local time.
The Oregon Department of Emergency Management announced that small tsunami waves would likely reach the coast around 11:40 PM local time. Wave heights could range from 30 to 60 centimeters, with officials urging residents to avoid beaches, harbors, and marinas until the advisory is lifted.
“This is not a major tsunami, but dangerous currents and strong waves may pose risks to those near the water,” the department stated. Oregon, along with much of the West Coast, including British Columbia, Washington, and California, remains under a tsunami advisory.
Warnings Extend to Other Regions
Furthermore, multiple aftershocks, some as strong as 6.9 magnitude, followed the initial quake. In Petropavlovsk-Kamchatsky, buildings sustained damage, and power outages occurred. Russian news agencies reported that several individuals sought medical assistance, but no serious injuries were confirmed.
Japanese nuclear power plants along the Pacific coast reported no abnormalities following the quake. Tokyo Electric Power Company Holdings, which operates the Fukushima Daiichi nuclear power plant, confirmed that about 4,000 workers took shelter on higher ground while monitoring the situation remotely.
Philippine authorities warned coastal provinces of possible tsunami waves under one meter, advising residents to stay away from beaches and coastal areas. Teresito Bacolcol of the Philippine Institute of Volcanology and Seismology emphasized that even smaller waves could pose dangers for swimmers.
Additionally, New Zealand authorities also issued warnings about “strong and unusual currents and unpredictable surges” along their coastlines. The government emergency management agency advised people to stay out of the water and away from beaches, harbors, and rivers.
However, this earthquake is the strongest to hit the Kamchatka Peninsula since 1952, with the local branch of the Geophysical Survey of the Russian Academy of Sciences reported that while the situation remains “under control,” aftershocks could persist for up to a month. They cautioned against visiting certain coastal areas.
Earlier in July, five powerful quakes, including one with a magnitude of 7.4, struck near Kamchatka, as the largest quake occurred at a depth of 20 kilometers, 144 kilometers east of Petropavlovsk-Kamchatsky.
On 4 November, 1952, a magnitude 9.0 quake in Kamchatka caused significant damage but no reported fatalities, despite generating 9.1-meter waves in Hawaii.
