A powerful earthquake with a magnitude of 8.8 struck off the coast of Russia's Kamchatka Peninsula, causing significant damage and generating a tsunami with waves reaching up to four meters. The quake, described as the strongest in decades by local officials, has led to injuries in the remote region and widespread evacuations. Tsunami warnings have been issued across the Pacific, with Japan and Hawaii ordering residents in coastal areas to move to higher ground. Authorities in Japan are preparing for waves of up to three meters to hit the eastern seaboard, recalling the devastation caused by the 2011 disaster. Aftershocks are expected, and emergency services are on high alert as the situation develops.
