Scientists in Russia have revealed the geological impact of an earthquake that struck Russia's far east and prompted tsunami warnings as far away as Hawaii. The Kamchatka Peninsula and surrounding Pacific Rim regions faced seismic instability after an 8.8 magnitude earthquake struck off the Russian coast on July 30.

At 11:24 am local time on July 30, 2025, a powerful earthquake struck offshore of the Kamchatka Peninsula, triggering a tsunami in the Pacific Ocean.

Kamchatka is a 1,250-kilometre-long peninsula located in the Far East of Russia. The Pacific Ocean and the Sea of Okhotsk serve as the eastern and western coastlines of the peninsula, respectively.
