Thanks for posting. Thank goodness this one doesn't seem to have done any major damage to people, but there could be more to come.

Alaska experiences 8.2 magnitude earthquake, largest in decades

Alaska experienced one of its largest earthquakes in decades on Wednesday night.

The 8.2 magnitude earthquake, which also sparked fears of a possible tsunami, hit at 10:15 p.m. local time, and its epicenter was 65 miles off the Alaska Peninsula village of Perryville, according to the Alaska Earthquake Center. The quake is the largest since 1965, according to United States Geological Survey earthquake records for Alaska.

There were no immediate reports of injuries or major damage, the Anchorage Daily News reported.

A tsunami warning was issued for various parts of the state shortly after the earthquake, though it has since been canceled. Residents had been advised to move to higher ground in the event of an impending tsunami.

"All #Tsunami alerts for the #Alaska coastline have been cancelled," the National Tsunami Warning Center said. "Remember, strong and unusual currents may continue for several hours. If you have damage, please report it to your local officials. Stay safe, get some rest, and we'll keep the watch for you. Good night."

A line of cars evacuates the Homer Spit in Homer, Alaska on July 28, 2021, after a tsunami warning was issued following a magnitude 8.2 earthquake. The tsunami warning for much of Alaska's southern coast was canceled when the biggest wave, of just over a half foot, was recorded in Old Harbor. Alaska.

All roads lead out of Homer, AK because it's "The End of the Road". More seriously, I think it is pretty low-lying and flat, so the precaution was wise.

A similar event a few decades back produced a different result.

Some people are scared to death of heights, enclosed spaces, etc. Personally, this is my worst case scenario.
