Hawaiians urged to evacuate as millions under tsunami threat after 8.7 earthquake strikes off coast of Russia --World's biggest earthquake in 14 years sparks Pacific-wide tsunami fears | 29 July 2025 | Residents in Hawaii are being urged to evacuate from coastal areas, as millions of Americans remain under threat of a tsunami following a massive 8.7 magnitude earthquake that struck off the coast of Russia. Preliminary data from the U.S. Geological Survey shows the quake reached a magnitude of 8.7 and struck about 84 miles east-southeast of Kamchatska at around 7.24pm EST. It has already caused a tsunami of up to 13 feet to strike the coastal area, and tsunami warnings are now in effect for parts of Alaska's Aleutian Island and Hawaii while a tsunami watch has been expanded to cover the entire West Coast of the United States. Meteorologist Matthew Cappucci also urged Americans to "prepare to evacuate vertically if warnings are issued."
