Tsunami waves flooded a coastal village in Russia after a powerful offshore earthquake.

The magnitude 8.8 tremor struck off the eastern coast of Kamchatka at 11:25 am local time (UTC+12) on Wednesday, July 30. The US Geological Survey reports that the quake occurred at a depth of 19.3 kilometres.

Authorities said the powerful shock generated tsunami waves as high as 13ft along Russia's coastline, prompting evacuations and damaging buildings.

Four waves struck the town of Severo-Kurilsk in the Kuril Islands.

Mayor Alexander Ovsyannikov told local media that the third wave caused the worst damage, hitting port infrastructure and vessels in the harbour.

The tremblor also sent tsunami waves across the Pacific, heading toward Japan, Hawaii, and the west coast of the United States.

A few hours after the jolt, more than two million people near the Pacific were advised to evacuate. Warnings were also issued in China, the Philippines, Indonesia, New Zealand, and even in Peru, Chile, and Mexico.

Local reports said the highest tsunami waves were recorded in the Hawaiian Islands, reaching up to 5.7 ft.

Officials confirmed it was the sixth strongest seismic event ever recorded in history.

The Kamchatka Peninsula lies within the Pacific Ring of Fire, an area known for intense seismic and volcanic activity.
