Tsunami waves have begun hitting US shores following a powerful 8.8-magnitude earthquake off Russia’s Kamchatka Peninsula. Initial waves struck Alaska and have now reached Hawaii, where water levels in Haleiwa, Oahu, rose over 4 feet, according to the National Oceanic and Atmospheric Administration (NOAA).

A tsunami warning—the highest alert level—is in effect for Hawaii and parts of Alaska’s Aleutian Islands, while the US West Coast remains under advisory. Waves are expected to arrive along the coast over the next several hours.
