Alaska usually averages about 40,000 earthquakes a year but 2018 was exceptional, with more than 55,000.

No doubt the thousands of aftershocks from our November 30th M7.0 contributed to the increase.

Looks like a whole lot of shaking going on.

This thread made me look at a map upon which I saw the town of Deadhorse, Alaska. That's even funnier that my previous favorite which was Big Otter, West Virginia.

Perhaps an admin or someone could move this to Geology and Planetary Surfaces....

Pretty impressive. Is it just Alaska, or or other areas seeing anything similar?

Hey, an Admin put it here. I value my completely volunteer and totally unpaid job too much to move it without permission.

I've long said you can tell the places where a lot of towns were named by young single men. Look at a map of Gold Country in California.

Here in Washington, my favorite is probably "Humptulips".

I posted this casually...sort of a “Hey, whattayaknow” kind of thread...rather then a science discussion. But I’m not averse to moving it.

ETA: Done.

I haven’t seen any other info on other states or elsewhere on the Ring of Fire. That graphic just happened to show up in my Facebook feed.

I thought it might be cool to see an animated version showing them in sequence. A search turned up some nice charts. This one at thinkgeoenergy.com (http://www.thinkgeoenergy.com/animation-by-noaa-showing-off-seismic-activities-around-the-globe/) shows earthquakes in sequence worldwide from January 2001 to December 2015.

The producers should have used the William Tell Overture as background music.

How about rock music?
