Earthquake Swarm in Arkansas Intensifies. Memphis, Tennessee could be epicenter for the next big one

I am sorry if this is "redundant information", but there is a volcanic past for Arkasas, Missouri and W. Virginia. Not to insinuate that this has to do with EQ activity, but just sayin'.

Yes, they account for the deep old faults.

Have to add, watch the webicorder, the quakes are popping off every few minutes or so.

Most surficial rocks in Arkansas are sedimentary, but there are some igneous rocks (with adjacent contact metamorphic rocks) and very low grade regional metamorphic rocks in Arkansas also. The most recent igneous activity in Arkansas occurred some 90 to 100 million years ago.

If that type of activity occured again.........I don't think we will be around to discuss it....

To me 706 quakes since August 2010 is a hell of a lot! Forgive me if I'm wrong.
If the majority of these quakes are indeed caused by fraking then it really dose need to be stopped. Especially when you have mentioned the fact that deep well injection disposal is a cause of quakes.

I really do hope that this dose not lead to a major earthquake in the areas in question.

Actually it was at its most intense last November/December time so the last 2 or 3 days is not sufficient time to show if this is a renewed intensity.



Putting this in perspective using the amount of energy released for all quakes over mag 1.0 since 01/01/2010 we see this



I leave you to decide whether the current 'swarm' is of any significance.

This one will update when you click it.

I have been following and interested in EQ's since I was very young. I don't know much about all the technical stuff and have just recently (last couple of months) begun to monitor webicorders and such. I have followed all the EQ threads and I am just fascinated but a little worried as well.

Arkansas has bothered me quite a bit lately, so today's earthquakes have really peaked my interest and even more worrisome. I would love to get my hands on "Gasland" and have been to numerous stores in my area to find it to no avail. So I guess I will be ordering it online in the next couple of days.

Just had another EQ in AR. Was watching it on the webcorder as it came through.

Thank you for the charts, puts it more into perspective.

Could somebody post the link for the Arkansas Webicorder please....Thanks in advance.

You are "right as rain" Cloudinthesky. Thankyou for the geology lesson. (smile)

Thanks Puterman. Are there any links to watch the quakes "live" as they happen?

ETA: Or can I just re-click on your links for updates? Please forgive me for my intelligence in this matter.

I absolutely agree that there have been other periods where there were spikes of greater activity. And that's my point. This is an ongoing swarm which I thought was about to stop after a lull. Maybe you could give us a total accumlated energy release for the entire year. It would add up to a significant release of energy. This energy is loading up the stresses on other fault networks. I am not looking at today's events without trying to understand the entire picture.

I am fully aware that the swarm could stop suddenly. And this period may be the last gasp of an ancient fault coming unglued. Or this may be the begining of a sequence of events which sets of another major faultline.

Even if there isn't another quake. This long lasting swarm will have consequences and will cause another area to readjust to this new dynamic.

And for those that have read my previous writings, you will be aware that I have water on the brain. We cannot rule out the groundwater. Nor the moon. (I won't get into that now, and it reminds me...) The area has recieved lots and lots of precipitation. The aquifers are charged and the area will be saturated when there is a major thaw. The ground is sandy. Water+sand+shaking=liquidification.

Puterman, could you put up the map with the epicenter .96km from the fracking pad. And maybe even include a close up shot of the fracking activity captured on the satelite image.

If you believe I'm being alarmist, just ask kennylee if he thinks so. Not long ago I was not ready to suggest there was something bigger brewing. I downplayed my concerns. And even wrote that I thought the four quakes back in 1811/1812 were probably not as big as some geologists believe.

How big?

7.3 magnitude.

But I don't think it will be just one quake. It will be a series of quakes.

I wished I had a "Do Over" in life........Those like the OP hopefully will keep us a step ahead.,,,

As many members here on this thread.......I too live in the region (SW MO / AR boarder)....

All of the snow from the last two snow storms that hit Missouri and AR melted over the past two days as temps hit 50+.......

Thank you for that update. Now the question. Is the recent thaw and charging of the aquifer part of the equation?

Here is a link to Arkansas USGS

There is a lot of information there on past and present events.

Also a link there to most recent quakes: earthquake.usgs.gov...

I noticed that the area surrounding Caney, AR is below 400 feet... which will all be under water when a physical (not magnetic ) pole shift occurs. You're gonna want to be above 1000 feet at a minimum to save yourself from the sloshing effect if/when it does happen.

ONE of several possibilities...which could explain why retired Naval Officers are moving to Arkansas.

Good question.

What about all the water they pump into it when they are fracking?

There is a new method they are experimenting with that will use LP gas, which they ignite underground to accomplish the fracking explosively. Will that be better or worse? Who knows.

Fracking:










I highly encourage anyone wanting to learn more to visit the Gasland website:

Now keep in mind that these wells can be up to 8,000 ft deep. There are literally thousands upon thousands of these wells in the region Robin is speaking of. Thousand of wells all producing these cracks/fissures under your feet....forcing high-pressure contaminated water into the earth. What in the hell are we doing to this planet???
