Tsunami warning downgraded or canceled across Gulf of Alaska after magnitude 7.9 earthquake

Update | 4:35 a.m.

Reporters in many coastal communities say evacuations have been called off. Tsunami advisories remain in effect in some areas. Advisories mean that while a wave has been recorded in the Gulf of Alaska, it’s not big enough to require evacuations. Being in or on the water is still dangerous, and there may be unexpected tides or currents.

“They’re still detecting aftershocks out at the original earthquake location in the central Gulf,” said Tom Ainsworth of the National Weather Service in Juneau. “So in other words, there will still be some earthquakes and some water level fluctuations out along the coast, but the warning threat has been canceled.”

Seismologist Michael West with the Alaska Earthquake Center and Alaska Department of Military and Veterans Affairs spokesman Jeremy Zidek told members of Alaska Public Media’s newsroom in Anchorage that no damage had been reported from the earthquake itself.

From earlier this morning, Ted Panamarioff in Kodiak shared this video of tsunami warnings and evacuation orders blaring in the streets.

The U.S. Tsunami Warning System reports tsunami warnings across the Gulf of Alaska have been canceled or downgraded. Additional information and analysis have better defined the threat.

  • The Tsunami Watch is canceled for the coastal areas of California, Oregon and Washington from The California/Mexico border to The Washington-British Columbia border.
  • The Tsunami Warning is canceled for the coastal areas of British Columbia, Southeast Alaska, South Alaska, and the Alaska Peninsula from The Washington-British Columbia border to Hinchinbrook Entrance in Alaska, 90 miles east of Seward.
  • The Tsunami Warning is canceled for the coastal areas of South Alaska and the Alaska Peninsula and Aleutian Islands from Chignik Bay to Attu.
  • For other US and Canadian Pacific coasts in North America, there is no tsunami threat.

The warning system reported several waves around the state of under a foot. 

  • At 3:29 a.m., Kodiak observed 0.6-foot wave

Weather service forecaster Tom Ainsworth in Juneau said this about the capital city.

“For the Juneau area, it’s highly unlikely that there will be significant waves felt this far in the inner channels.”

On Facebook, CBJ Emergency Programs Manager Tom Mattice  says he’s is not calling for an evacuation of the capital city. Mattice writes that he’s at the National Weather Service Office. He says tides in Juneau should be below 8 feet when the waves are expected to hit, “So we have (a) fair tide margin. Models say we should be ok.”

In Sitka, KCAW’s Robert Woolsey reports that their community’s warning sirens are also sounding. KCAW’s Emily Kwong reports the town is evacuating. 

In Kodiak, KMXT reporter Kayla Desroches reports people moving to local schools and up Pillar Mountain. There are reports of tsunami warning sirens sounding there as well.

In Homer, about 50 people have gathered at the South Peninsula Hospital. The city has opened Homer’s High School as a shelter.

In Unalaska, KUCB’s Zoe Sobel describes a chaotic scene with residents in their pajamas getting into their cars and heading for places 50 feet above sea level.  

We’ve also had reports of a strong earthquake felt on the Kenai Peninsula and tremors felts in Southeast Alaska.
