Biggest in 50 Years: Alaska Rocked by Powerful 8.2 Earthquake, Follow-up Tsunami Warnings

Simon Kent – July 29, 2021

A powerful earthquake rocked Alaska’s southern coast early Wednesday morning, with prolonged shaking in the aftermath that prompted tsunami warnings across nearby coastal areas.

AP reports only minor damage was recorded, but officials said that could change after sunrise and people get a better look at an earthquake event set at the biggest in 50 years.

The U.S. Geological Survey said the quake was magnitude 8.2 and hit 56 miles (91 kilometers) east southeast of Perryville, Alaska at about 8:15 p.m. Wednesday.

The National Tsunami Warning Center canceled the warnings early Thursday when the biggest wave, of just over a half foot, was recorded in Old Harbor.

A tsunami warning that had also been issued for Hawaii was also canceled, and officials said there was no threat to Guam, American Samoa or the Commonwealth of Northern Mariana Islands.

Patrick Mayer, the superintendent of schools for the Aleutians East Borough, told AP he was sitting in his kitchen in the community of Sand Point when shaking from the quake started.

“It started to go and just didn’t stop,” Mayer told the Anchorage Daily News. “It went on for a long time and there were several aftershocks, too. The pantry is empty all over the floor, the fridge is empty all over the floor.”

On the Kenai Peninsula, a steady stream of cars were seen evacuating the Homer Spit, a jut of land extending nearly 5 miles (8 kilometers) into Kachemak Bay that is a draw for tourists and fishermen.

Major solar flare triggers 3 strong earthquakes in Alaska (M6.3), Argentina (M6.3), Russia (M6.4)

Strange Sounds – December 1, 2020

Well, if you look back at data from the past two days, there is a clear correlation between the proton density sent from the sun and the occurrence of large earthquakes (M > 5.6), with a time shift of 1-2 day(s).

The biggest solar flare in more than 3 years occured on Nov. 29th, triggering widespread radio shortwave outages and hurling a huge CME in space.

Luckily, the small sunspot that erupted wasn’t facing Earth during its explosive event. But still, particles from the solar eruption may have triggered a series of 4 strong earthquakes that hit across the world within less than 12 hours between Nov. 30th and Dec. 1st.

M6.4 Russia – Nov. 30th, 22:54:34 (UTC)

The first earthquake of the series is a very deep M6.4 quake that hit 88 km SSE of Sovetskaya Gavan’, Russia.

The offshore quake epicenter was situated at a depth of 587km (364.7 miles) and no tsunami was created.

M6.3 Argentina – Nov. 30th, 22:54:59 (UTC)

Just 20 seconds after the first strong quake of the series, another big blast rattled 76 km WSW of San Antonio de los Cobres, Argentina.

Although very deep (147.8 km or 91.8 miles), the quake was reported by at least 16 people, most reporting very small shaking.

It is worthwhile to report that a M5.9 earthquake (so a big one too!) hit about the same region on Sunday, Nov. 29th at 1:40 p.m. local time – the same day than the solar eruption.

M6.3 Alaska – Dec. 1st, 16:22:40 (UTC)

Finally a M6.3 earthquake hit offshore, 38 km (23.6 miles) ESE of Nikolski, Alaska at a depth of 23 km (14.3 miles).

Eight reports of shaking have already been published on the USGS homepage.
