There was a 7.8 trembler off the Alaska coast.

No damage and no significant tsunami:

A powerful earthquake located off Alaska’s southern coast jolted some coastal communities late Tuesday, and some residents briefly scrambled for higher ground over fears of a tsunami.

There were no immediate reports of damage in the sparsely populated area of the state, and tsunami warning was canceled after the magnitude 7.8 quake off the Alaska Peninsula produced a wave of a less than a foot.

According to the U.S. Geological Survey, the earthquake struck Tuesday at 10:12 p.m. local time, centered in waters 65 miles south-southeast of Perryville, Alaska at a depth of 17 miles.

Because of its location, nearby communities along the Alaska Peninsula did not experience shaking that would normally be associated with that magnitude of a quake, said Michael West, Alaska State Seismologist.

More than a dozen aftershocks of magnitude 4.0 or higher were reported immediately after the earthquake, he said by telephone from the Alaska Earthquake Center at the University of Alaska Fairbanks.

“We got people here who are going be working all night,” West said early Wednesday morning. “These aftershocks will go and go and go and go.”

The Alaska-Aleutian Trench was also where a magnitude 9.2 quake in 1964 was centered. That remains the second most powerful earthquake ever recorded. The temblor and ensuing tsunami caused widespread damage and killed 131 people, some as far away as Oregon and California. Alaska is the most actively seismic state. Nearly 25,000 earthquakes have been recorded in Alaska since Jan. 1, according to the center.

I really hope that the fault line is not going to open up like a zipper.
