Tsunami.gov has a tsunami advisory posted.

[Lurkina.n.Learnin]

If I had a boat in Cresent City harbor I think I would head out to sea until it passes. They seem to get it even when there is no warning.

Shemya? Attu?

8.0 is indeed a very strong quake:

19 minutes ago:

“A tsunami Advisory is now in effect which includes the coastal areas of Alaska from Samalga Pass, Alaska (30 miles SW of Nikolski) to Attu, Alaska ...

Stay away from the beach. Tsunamis can travel hundreds of miles per hour, so you can’t escape if you’re close enough to see one.”

I didn’t feel a thing here in SoCal.

Did you feel it?

6.6 off the coast of Peru reported a few minutes ago.

I was just watching the Weather Channel and they had a multiple choice question about which state had the most severe earthquakes, and the answer was Alaska.

[TXnMA]

Ever since LFK started making more noise about shooting missiles and popping nuke tests, I've been monitoring four seismic stations -- strategically placed around his nuke test site:

Those stations produced nice, diagnostic "signatures" of his last test, and should do for future ones.

I spotted the first of this swarm of quakes and, from the seismic signals, called it as "near the Kamchatka Peninsula".

Now, the USGS quake map of the area shows a whole cluster near that same fault inflection -- and reports them as either, "~80 km E of Nikol'skoye, Russia" or, "~220km WNW of Attu Station, Alaska".

Actually, there are a dozen or more strung out just north of the Aleutian islands -- with one outlier on the southern side of that fault.

The weird thig is, with so many big quakes strung out in time like this, virtually every seismograph in the world is virtually black with overlapping signal traces:

For now, it will be easier for seismologists to separate out the individual seismic signals themselves-- rather than to try to decipher anything from overlapping seismograph traces...
