Now eyeballing Quake watch thread nervously.

thanks for posting. I knew we have had some extra activity lately here in AK, and 7 is nothing to shake a stick at....

Dang!

Hope these whoppers don't hurt many lives. Thank goodness this Alaskan quake is over 100 kms deep, mitigating the tsunami potential.

Tsunami warning for Alaska:

THE TSUNAMI WARNING REMAINS IN EFFECT FOR THE COASTAL
AREAS OF ALASKA FROM NIKOLSKI ALASKA TO ATTU ALASKA

ESTIMATED TSUNAMI START TIMES FOR SELECTED SITES ARE...

SHEMYA ALASKA 124 PM AKDT JUNE 23
ADAK ALASKA 134 PM AKDT JUNE 23
SAINT PAUL ALASKA 304 PM AKDT JUNE 23

tsunami alert


So much for seismic quiet.

And it's cruise ship season up there.

The USGS downgraded the Kermadec quake to a Mag 6.9 mww, while Geofon have it as Mag 6.8 Mw, and EMSC have Mag 7.0 Mw.


It does bug me that the aftershocks were large, relative to the size of the main shock.
Using the USGS recent quake map:



That's only a 0.6 Mag difference...it is possible there is a larger quake still to come.

I have wondered for some time, so will ask those with more knowledge.....with the permafrost melting in Alaska's interior, would a large quake cause liquefaction? What other concerns with the softening ground be relative to earthquake activity?

a reply to: nugget1

What a great question. I'm not an expert, but my guess is that the permafrost/soil would indeed be highly susceptible to liquefaction.

On a tangent, here is a link to the webicorder from Little Sitkin Volcano (site of the Mag 8.0 and aftershocks). Link, courtesy of the Alaska Volcano Observatory.

The latest: are they talking to each other???

I went to have my supper and someone threw the earthquake machine switch!

The initial values looked like an 8, 2 x 7 and 2 x 6 but I see those have come down now.

The monsters from Godzilla are communicating and about to awaken? lol

Raoul's (Kermadec Is.) feed via GEE is quite active tonight. I have a strong hunch that that end of the plate isn't finished making itself heard.

Cthulhu & Godzilla are planning a takeover.

6.9 Rat Islands, Aleutians courtesy of EMSC. Guess it's not done making it's opinion known yet, either.

Is this some kind of record or something...
for that many higher quakes...
at the same time...
in two different places...
in such a short time span???

Just wondering!!!

a reply to: radpetey

Maybe I shouldn't take credit for anything. I said it was going to be bigger than an 8. It came it at 7.9M. I was quite excited to finally see all the squiggly lines on the Alaskan webicorders. I missed the actual event because I was digging. I was more shocked to see New Zealand chimed in. I think you all know how I rant about double taps and and clustering, well, we just got a double whammy. But let's forget all that. The two earthquakes are almost on the same latitude. Hmm.

178e

177w



I would wonder about Yellowstone, except these earthquakes are not on the mainland. but it's worth having a look I suppose.

Did I write latitude? I meant longitude. Yellowstone is quiet.

Geepers! When I try to edit,
I either get a Yahoo links page,
or it says I've exceeded my 4 hour window!!!
It's only been 2 hours!!!

Anyhoo...another 6.6 in Alaska!
Holy #, this is crazy!
I want to stay up all night.
I'm afraid I'll miss something!!!
WOQ

And yet another sizable rattler out of the Aleutians. A 6.6 in the Rat Islands, according to the EMSC. The USGS says the same, placing the nearest location as Buldir Island. The difference between this quake and previous ones is the depth. EMSC says about 30 km deep, USGS says 35 km deep.
