Tsunami waves hit Hawaii following a substantial earthquake in Russia's eastern region.

Tsunami waves hit Hawaii following a substantial earthquake in Russia's eastern region.

On July 30, 2025, a magnitude 8.8 earthquake hit off Russia's Far Eastern Kamchatka Peninsula, marking the most powerful quake in the region since 1952, according to Russian scientists. The epicenter was approximately 119 km east-southeast of Petropavlovsk-Kamchatsky.

The earthquake triggered tsunami waves of up to 5 meters (16 feet) in some areas, prompting evacuations of over two million people in various countries. The US Tsunami Warning System warned of hazardous tsunami waves spreading across the Pacific.

The Pacific-wide tsunami affected broadly the basin, with most locations experiencing waves of 1 meter or less. However, a locally extreme wave run-up of 19 meters was recorded on Shumshu Island. Despite the quake’s immense strength—the most powerful since the 2011 Tōhoku event and tied as the sixth largest ever recorded—the overall damage was relatively low.

In Kamchatka Krai and Sakhalin Oblast, the earthquake caused moderate damage and multiple injuries but very limited destruction compared to other quakes of similar size. One indirect fatality and 21 injuries were linked to tsunami-related evacuations in Japan.

A resident in Petropavlovsk-Kamchatsky described the shaking as lasting for at least 3 minutes. The tsunami affected the region, with three waves recorded in Japan, where the largest reached 1.3 meters (4.3 feet). In Severo-Kurilsk in the northern Kuril Islands, tsunami waves exceeded 3 meters, with the largest up to 5 meters.

Tsunami waves struck parts of Kamchatka, partially flooding a port and a fish processing plant. In response, the US Coast Guard ordered ships out of harbours as the tsunami approached Hawaii, where coastal residents were told to get to high ground or the fourth floor or above of buildings.

The US Geological Survey (USGS) forecasts indicate a high probability of large aftershocks, including magnitude 7+ earthquakes, continuing for weeks after the main event. Power to the Sakhalin region had been cut off due to damage to the electricity grid.

Despite the significant impact, the overall damage was relatively low, with localized areas experiencing more severe effects. Aftershock activity remains a concern for regional seismic risk management.
