An 8.0-magnitude earthquake was recorded in the Aleutian Arc of islands, sometimes called the Rat Islands, between Russia and Alaska at 4:53:10 p.m. EDT (11:53 a.m. local time) on Monday.

The quake created a tsunami warning for the coastal regions of Alaska from Nikolski to Attu.

What was originally a 7.1-magnitude earthquake was upgraded to 8.0. It seems to be too deep to pose a threat to Hawaii, according to the National Weather Service. The latest bulletin indicates that other areas of the U.S. and Canadian Pacific coasts would not be affected.

The alert says: “No tsunami threat exists for other coastal areas in the Pacific, although some other areas may experience small nondestructive sea-level changes lasting up to several hours.”

By The Extinction Protocol.

ALASKA – Sharply increased seismic activity and volcanic eruptions in the Aleutian Islands and the far western Brooks Range are being investigated by scientists. The Alaska Volcano Observatory says the activity over the past few months is the most seen by the station in 26 years. On the Alaska Volcano Observatory three volcanoes are classified with a yellow alert level—signifying signs of elevated unrest above known background levels—and three are at an orange alert level—heightened unrest with increased likelihood of eruption. Orange is the second-highest alert level after red signifying an eruption that is imminent or underway.
