A powerful 8.7-magnitude earthquake struck Russia’s Far Eastern Kamchatka Peninsula early Wednesday, triggering tsunami waves that reached parts of Japan and sparked evacuation alerts across the Pacific region.

The epicenter was located about 119 kilometers (74 miles) from Petropavlovsk-Kamchatsky, a city of around 180,000 people. The quake caused structural damage in some Russian coastal areas, and tsunami waves measuring 3 to 4 meters (10 to 13 feet) were reported near the epicenter. No major injuries have been reported so far, officials said.

In Japan, the Meteorological Agency reported that tsunami waves reached Tokachi on Hokkaido’s southern coast, measuring 40 centimeters (1.3 feet). Another wave of around 30 centimeters (1 foot) was observed in Nemuro, located on Hokkaido’s eastern coast.

The Pacific Tsunami Warning Center issued alerts across several countries and territories including the United States, Chile, the Solomon Islands, and New Zealand. Authorities in Alaska and Hawaii also raised emergency alerts.

Tsunami sirens sounded across Honolulu, Hawaii, urging residents and tourists to evacuate to higher ground. “Urgent action should be taken to protect lives and property,” the Pacific Tsunami Warning Center said, warning that waves could exceed 3 meters in some regions.

The first tsunami wave struck Severo-Kurilsk, a key settlement on Russia’s Kuril Islands. Governor Valery Limarenko confirmed evacuations had taken place there as a precaution.

The event has caused widespread concern throughout the Pacific basin, renewing focus on earthquake preparedness and international tsunami warning coordination.
