HONOLULU - Parts of Alaska are under Tsunami Warnings while the entire U.S. West Coast and the state of Hawaii are under Tsunami Watches after a monster magnitude 8.7 earthquake struck off the east coast of Russia Tuesday evening.
The quake hit at 1:24 p.m. Hawaiian Time (7:24 p.m. ET, 2:24 a.m. Wednesday local time) about 85 miles east of Kamchatsky off the eastern Russian coast.
The Pacific Tsunami Warning Center says a quake of that magnitude may have triggered a tsunami that would be destructive to coastal areas even far from the epicenter.
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 threat to the U.S. Coast is still under evaluation.
Waves are expected to reach Shemya at 4:46 p.m. Alaska Daylight time, and 5:46 p.m. AKDT in Adak.
