HONOLULU - One of the strongest earthquakes ever measured struck off the eastern coast of Russia on Tuesday evening, triggering fears of a tsunami across much of the Pacific Ocean basin, including the shores of Hawaii, southern Alaska, the entire U.S. West Coast and British Columbia.
Tsunami Warnings are in effect for Hawaii and parts of Alaska, while the entire U.S. West Coast and British Columbia are under a Tsunami Watch after a monster magnitude 8.7 earthquake struck just east of Petropavlovsk, Russia."A tsunami has been generated that could cause damage along coastlines of all islands in the state of Hawaii," the Pacific Tsunami Warning Center said. "Urgent action could be taken to protect lives and property."
Initial data from the quake suggest tsunami waves reaching more than 9 feet above the tide level are possible along some coasts of the Northwestern Hawaiian Islands and Russia, according to the PTWC. Waves of 3-9 feet (1-3 meters) are possible along some coasts of Hawaii, Japan, and Guam. The first waves would reach Hawaii around 7:17 p.m. Hawaiian Time (1 a.m. ET), the PWTC says.
The Tsunami Watch along the West Coast includes inland waters connected to the Pacific Ocean, including the San Francisco Bay in California, the Columbia River coast on the Washington and Oregon border, and the Strait of Juan de Fuca that separates Washington's Olympic Peninsula with British Columbia's Vancouver Island.
Waves are expected to reach Shemya at 4:46 p.m. Alaska Daylight time, and 5:46 p.m. AKDT in Adak.
