Tsunami Advisory issued in Alaska after massive quake strikes off Russia near site of July’s historic temblor

A magnitude 7.8 earthquake shook part of eastern Russia Friday morning local time, triggering tsunami fears in Alaska.

ADAK, Alaska – A 7.8 earthquake off the coast of Russia has triggered a Tsunami Advisory for the Aleutian Islands in Alaska on Thursday.

The quake struck just before 11 a.m. Alaska Daylight Time (3 p.m. ET) and was centered about 90 miles east of Petropavlovsk, Kamchatka, according to the U.S. Geological Survey.

A Tsunami Advisory stretches from Amchitka Pass, Alaska, (about 125 miles west of Adak) to Attu, Alaska.

Any tsunami waves would reach Shemya around 12:20 p.m. AKDT (4:20 p.m. ET)

A Tsunami Advisory is a lower-rung alert for a tsunami, issued when small waves may impact an area. Strong currents could be dangerous to those in or near the water, and minor flooding of beaches and harbors is possible.

No other U.S. or Canadian continental locations are in an alert zone, according to the U.S. Tsunami Warning Center. However, the agency is warning there could be tsunami waves of 3-9 feet (1-3 meters) along some parts of the Russian coast.

The quake is likely an aftershock of the historic 8.8 earthquake that struck on July 29, sending tsunami alerts across much of the Pacific Ocean. While some minor waves were reported in Hawaii along the U.S. West Coast, there was no significant damage reported.

Updates to follow soon.
