A magnitude-8.7 earthquake in Russia’s Far East early Wednesday prompted tsunami warnings in parts of Japan, Alaska and Hawaii. Damage and evacuations were reported in the Russian regions nearest the epicenter on the Kamchatka Peninsula. Japan’s meteorological agency issued a tsunami alert for Japan’s Pacific coast, saying waves up to 3 yards could arrive along the northern Japanese coasts less than half an hour after the alert. In the United States, the Pacific Tsunami Warning Center said a tsunami had been generated by the quake that could cause damage along the coastlines of all the Hawaiian islands.
