An 8.8 magnitude earthquake off Russia’s eastern coast has led to tsunami warnings in over twenty countries. Waves exceeding four meters have already reached several coastal areas and millions of people have been ordered to evacuate beach areas.
The powerful earthquake occurred on July 30, 2025, off the Kamchatka Peninsula in Russia’s far east and is the strongest since the Tōhoku earthquake in 2011. According to the US Geological Survey (USGS), the epicenter was located 136 kilometers east of the city of Petropavlovsk-Kamchatsky.
Tsunami warnings have been issued for the USA, Russia, Japan, Canada, Chile, Peru, Ecuador, Mexico, the Philippines, Indonesia, Taiwan and China. The Pacific Tsunami Warning Center has warned that “a tsunami with significant widespread inundation is expected”.
First waves reach Hawaii and Japan
The first tsunami waves have already reached Hawaii, where waves exceeding 1.5 meters have been reported at Kahului on the island of Maui. Hawaii Governor Josh Green urged residents to immediately evacuate coastal areas.
— It is, again, not just a 3-foot wave. It is a forceful wall of water, Green said during a press conference.
In Japan, the first waves measuring 30 centimeters in height have reached the northernmost island of Hokkaido. The country’s meteorological institute has warned of waves up to three meters along Japan’s eastern coast and urged over 1.9 million people to seek safer areas.

Extensive damage in Russia
In Russia, the earthquake has caused extensive damage in Petropavlovsk-Kamchatsky, home to 181,000 people. According to Russian news media, many rushed out onto the streets without shoes and outerwear when the earthquake struck. A kindergarten collapsed and the power grid was damaged.
Tsunami waves measuring 3-4 meters in height have been recorded in the Yelizovo district on Kamchatka. The small port town of Severo-Kurilsk on the Kuril Islands was completely flooded and 2,000 residents were evacuated. Video footage shows water rushing between buildings, carrying boats and containers.
Warnings stretch across the Pacific
Tsunami warnings now cover large parts of the Pacific coast. In the USA, the highest warning level applies to Hawaii, parts of Alaska and northern California. Less severe advisories have been issued for the rest of the American west coast and parts of British Columbia in Canada.
Waves of 1-3 meters are expected to reach Chile, Peru, Ecuador and Costa Rica. Mexico’s navy has warned of waves up to one meter along the Pacific coast and urged people to stay away from beaches.
The Philippines, where authorities have warned of tsunami waves smaller than one meter, and New Zealand have also issued warnings about “strong and unusual currents”.
Robert Weis, tsunami expert at Virginia Tech, stated that the event should be taken seriously: “It’s right to be concerned about this event”.
The earthquake, which USGS has classified with a rare red warning level, could become one of the strongest ever measured and is estimated to potentially cause billions of dollars in damage.
