A powerful earthquake measuring magnitude 8.8 has struck off the coast of Kamchatka, in Russia’s Far East, triggering widespread tsunami alerts across the Pacific Ocean, including warnings for Russia, Japan, the United States, the Philippines, and as far as New Zealand.

The earthquake, which initially registered as an 8.0, was later upgraded to 8.7 and now officially recorded at 8.8, making it the largest earthquake of 2025 and the sixth strongest ever recorded in modern history. Tremors were strongly felt across Kamchatka’s sophisticated and sparsely populated region, with reports of injuries at Kamchatka Airport and localized infrastructure damage.

The National Emergency Management Agency (NEMA) and regional counterparts in Japan, Hawaii, and the Philippines have activated emergency protocols and issued tsunami warnings, urging residents in coastal areas to evacuate to higher ground.

According to Russian authorities, tsunami waves as high as 3 to 4 meters have already been observed along parts of the Kamchatka coast and surrounding Pacific areas. Authorities in the Philippines have instructed communities near the shoreline to evacuate immediately.

In Japan, train services in the eastern region have been suspended, and emergency alerts have been broadcast nationwide. The Japanese Meteorological Agency warned of possible severe sea-level changes and unpredictable currents.

While the full scale of damage is still being assessed, there are early reports of minor injuries and logistical disruptions. Several countries have placed emergency response teams on standby, with the United States Geological Survey (USGS) and Pacific Tsunami Warning Center closely monitoring the seismic activity and potential aftershocks.

In New Zealand, officials initially downplayed the risk due to the distance from the quake’s epicenter, but the upgraded magnitude has forced a reassessment of the tsunami threat. Coastal communities have been warned to stay away from beaches and marinas until further notice.

This earthquake is the most powerful since the 2021 magnitude 8.2 quake in Alaska, and draws comparisons to the devastating 9.1-magnitude 2011 Tōhoku earthquake in Japan, which caused a catastrophic tsunami and nuclear disaster.

Authorities across the Pacific Rim continue to monitor the situation, urging vigilance and preparedness as aftershocks remain likely in the hours and days ahead.
