An 8.0-magnitude earthquake struck in Alaska at 12:53 p.m. local time and it was widely felt by numerous communities in Alaska's scarcely-populated Aleutian Islands, per ABC7 News on Monday, June 23, 2014. There were no immediate reports of damage, but it did end up bringing about a tsunami warning for the Pacific coast of the United States.
By 3:00 p.m., the tsunami warning had been reduced to a tsunami advisory by the National Weather Service.
Yahoo News reported that Natasha Ruppert, a seismologist with the Alaska Earthquake Center stated that any communities that would have suffered earthquake damage were also under tsunami warnings. Due to these warnings, those people may not have been able to see if there was damage outside.
No injuries had been reported shortly after as well.
When the earthquake in Alaska, it was originally reported to have a magnitude of 7.1, but it was upgraded to an 8.0 shortly after. It was recorded at a depth of 60-70 miles and centered about 13 miles southeast of Little Sitkin Island.
The 60-70 miles depth is quite shallow for an earthquake in the Aleutian Islands in Alaska. Scientists have stated before that the shallower the earthquake is when it hits, the more likely it is to be felt by humans.
After the earthquake hit, the National Tsunami Warning Center located in Palmer, Alaska, issued a tsunami warning for coastal areas between Attu and Nikolski. Residents in those areas of the Aleutian Islands are being told to move to higher ground and inland while the warning persists.
Around 2:30 p.m., a second earthquake was reported, and it was said to be at a magnitude of 5.9, and that was downgraded from the preliminary magnitude of 6.2.
