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...

Oh, it was way off on the tail end of the island chain. Thanks for the info.

“The quake comes shortly after a powerful spewing of ash from the Klyuchevskoy volcano in Kamchatka.”

Do you have a URL you can share for data like that plot you posted of the seismograph in Laurens County? Those alternating color traces can be very helpful in sorting things out -- especially at times like this!

And that 15-minute/trace time base helps, as well...

I've been monitoring (publicly accessible) "GSN" stations -- which are, conveniently for my purposes, located in the Far East -- but are monochrome -- and use a one hour/trace timebase. Useful -- but, not elegant... '-)

Yes, it’s always good to include a link to the source. :)
Great info though.
