Topic: M8,2 Alaska Eartquake
Posted: July 29 2021 at 1:00am

Much of the Gulf of Alaska coastline from the Aleutians to Kodiak to Prince William Sound were under a tsunami warning Wednesday night following a strong earthquake off the Alaska Peninsula.

The earthquake, with a preliminary magnitude of 8.2, according to the USGS, hit 10:15 p.m. It triggered tsunami warnings from Samalga Pass in the Aleutians to Prince William Sound. A tsunami advisory was in effect for the rest of Alaska’s coastline, including Southeast Alaska and the western Aleutians.

There were no immediate reports of injuries or damage.

DJ Lots of aftershocks- a few around M6...but it looks like the M8,2 was the "main quake"...still a strong quake could start other quakes...

Tsunami Advisory in Effect for;

 * SOUTHEAST ALASKA, The inner and outer coast from Cape
   Decision, Alaska (85 miles SE of Sitka) to Cape
   Fairweather, Alaska (80 miles SE of Yakutat)

 * SOUTH ALASKA AND THE ALASKA PENINSULA, Pacific coasts from
   Cape Fairweather, Alaska (80 miles SE of Yakutat) to
   Hinchinbrook Entrance, Alaska (90 miles E of Seward)

 * ALEUTIAN ISLANDS, Samalga Pass, Alaska (30 miles SW of
   Nikolski) to Amchitka Pass, Alaska (125 miles W of Adak)
   including the Pribilof Islands


For other US and Canadian Pacific coasts in North America, 
the level of tsunami danger is being evaluated.  Further
information will be provided in supplementary messages.

DJ Strong aftershocks or other quakes could worsen tsunami risks. It could take 3 hrs+ before a Tsunami would reach Canada West Coast...maybe 12 hrs before Hawaii/Phillipines...

had an earthquake with M9/9+...so risks for tsunami in larger area may be limited-so far.

Update, July 29, 12:30 a.m.:

The tsunami warning that had been in effect from the Aleutians to Kodiak to Prince William sound has been canceled, an advisory is still in effect.

DJ If there is no tsunami warning for nearby area's risks for further away area's [url]https://www.rt.com/usa/530535-alaska-earthquake-tsunami-warning/[/url] or https://www.rt.com/usa/530535-alaska-earthquake-tsunami-warning/ ;

The US National Weather Service Guam has downgraded the possible threat, noting, “At this time, there is no tsunami threat out for Guam & the CNMI (Northern Mariana Islands).”

The National Weather Service added that Hawaii had elected to cancel its “Tsunami Watch” status, but confirmed that “all other Warnings and Advisories continue until further notice.”

The quake is the largest to hit the US since 1965, and the sixth-largest in the continent’s history. All the US’s most severe earthquakes have occurred in the state of Alaska.

DJ It was a strong quake-possibly resulting in increased of further quakes in the Pacific ring, strong after shocks...but for now "damage seems to be very limited"....
