And just a while ago there was another 5.5, says USGS, but that mag might drop some:

earthquake.usgs.gov...

That's a preliminary magnitude, and I saw it- seemed more like a 4.8- 5.2 to me.

As I suspected, check it out- LDEO graded that quake a 4.9, right in my range, but USGS hasn't changed it yet as of this post:

2013 1 8 18 45 12.0 55.75 -135.25 33.0 4.9 OFF COAST OF SOUTHEASTERN ALASKA

www.ldeo.columbia.edu...

I just love when that happens.


EDIT: ahh, they did update it on their new list:

earthquake.usgs.gov...

4.7

.8 mag off from the original report of 5.5, and that's too much. But the average between the LDEO and USGS is 4.8. Still in my range.

USGS will only list 2.5 and above....but you probably already knew that


There is a list somewhere that lists the smaller ones....Maybe the PNWS web page.

I will say that the mid 6 mags in that general area have next to none, when it comes to aftershocks!

There's a drop down menu that has the smaller EQs on the left side
under Choose Data Feed.

Yes, I already know this. My perma-settings for the USGS are set for to display all earthquakes (maxes out at 1,000) for the past 24 hours, magnitude -1.0 to 10.0, and all depths. I see the Cobb swarm just fine and other small events as well (within the US anyway) The lack of any apparent aftershocks for the Alaska 7.5 prompted the question. If they're listed on the PNWS page, then why not the map as well? To save space or something?
