The Aleutians are made up of some 70 islands in the Northern Pacific Ocean, extending about 1,200 miles westward from the Alaska Peninsula.
“The U.S. Geological Survey says the earthquake happened about 8:25 a.m. Alaska time, and it was centered about 55 miles southeast of Adak, a city in the Aleutian Islands. The Alaska Earthquake Information Center says in a statement that the quake was felt strongly in Adak and Atka, and shaking lasted up to one minute,” says the AP report.
No initial news of damage or injuries were reported, and no tsunami warning was issued.
“At this point, we've seen no ocean-surface disturbance,” said Bill Knight, a scientist at the tsunami warning center in Palmer, Alaska.
A magnitude 7.0 earthquake generally produces shaking around the 20 to 30 second range, making this earthquake hard not to feel in the city of Adak, approximately 60 miles from the seafloor’s epicenter.
Adak City Manager Layton Lockett confirmed the unusually long quake.
“It was kind of hard to miss,” Lockett said. “The strangest thing about this one was its length in time. I think people actually had time to get out of bed to see what was going on.”
According to the U.S. Geological Survey, there are more earthquakes in Alaska than any other state. California is the second most, with Hawaii coming in third.
