New Madrid Seismic Zone Activity

Anyone feel it? I was asleep.

Edit: two smaller quakes occurred earlier this week in a addition to the one mentioned above all around Dyersburg. Hopefully it's not the start of a swarm.

Given that we're talking about the New Madrid fault zone I'd gladly take a swarm of small ones over a big one.  Any time stuff shakes out there it makes me nervous even all the way over here in Knoxville!

Could be a foreshock...I doubt it. These bigger one's happen from time to time enough to remind everyone that the NMSZ exists, but I wouldn't worry too much about it. There was a 3.5 I think within the last couple of years. My QuakeFeed app goes off several times a week with 1.0-2.0's in the New Madrid area.

There will never be a warning. You might be lucky enough to be in the right place at the right time to see odd animal behavior en masse, but that's assuming you put 2&2 together within a decent amount of time. Maybe you're out in a field and happen to witness some sand blow activity...that would definitely be a sign and you would want to get the **** outta there before the ground liquefied.

I'm rambling as I think back to pursuing and attaining that BS in Geology 4 years ago.

Just a friendly reminder that the NMSZ is overdue by 30-50 years for another sizable quake. If that happens you will want to stock up on everything very fast as the transportation issues it will cause will be extreme regionally and moderate at the national level.

Could you explain this phenomenon in greater detail?

Thanks!


ETA: Basically, what is "sand blow" activity?

It's like a geyser, but with sand instead of water. In 1811/1812, they were observed in the crop fields at random before and after the big ones. There was so much pressure underground that it had to come out.

I'm reminded of all the hype before the last eclipse about the next one coming up in 2024 crossing the path of the 2017 eclipse and placing an X right over the NMSZ.  I'm not the superstitious type, but it does make me sit up and take notice.  Two eclipses crossing paths within 7 years of each other isn't something that happens every century.

I like the guy, he got me out of school for a day in 3rd grade.

Looks like there was another small quake this morning nearby in MO.  https://earthquake.usgs.gov/earthquakes/eventpage/nm60268696/executive
Nothing really to worry about IMO, but this is the most activity I have noticed for the area in a 7 day period in a while

Living in NEA If freaks me the freak out to think the next big one could hit at any moment. 

There is a little town east of Manila called Dell.  No more than a few blocks.  A fishing buddy was higher up at Entergy and was in a lot of disaster prep meetings.  He says they were told if another big one hits the area from Big Lake to just east of Dell would be gone.

There is a large cavern under that area that holds water and the earth above that cavern is mostly sand and isn

NMSZ continues to be more busy than average.  Its something I will certainly be keeping an eye on.
