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

reply to post by KathyG427


...my thoughts exactly! have you happened to be outside when one of the many eq's takes place?

So if any of you are wondering why I am so sure it will be upgraded, take a look HERE at 4:59. THAT is a 4.0 quake. Compare it to the one that just happened.


Edit to add: another quake just now...probably just under 2.0

This is the one I felt :

Magnitude 4.3
Date-Time

* Friday, February 18, 2011 at 08:13:35 UTC
* Friday, February 18, 2011 at 02:13:35 AM at epicenter
* Time of Earthquake in other Time Zones

Location 35.269°N, 92.382°W
Depth 6.3 km (3.9 miles)
Region ARKANSAS
Distances

* 4 km (3 miles) N (9°) from Greenbrier, AR
* 7 km (4 miles) SE (144°) from Twin Groves, AR
* 7 km (5 miles) SW (215°) from Guy, AR
* 21 km (13 miles) NNE (18°) from Conway, AR
* 59 km (37 miles) N (356°) from Little Rock, AR
* 419 km (260 miles) SSW (208°) from St. Louis, MO

They really need to stop drilling

thanks for the quick reply! I guess all we can do is assume they will keep stepping up as they have been, which is really concerning! I'm downloading GEE as we speak, finally going to get off my butt and stop asking questions and learn to figure it out myself - Puterman has alot of pages to catch up on when he gets to this that's for sure!

Okay, upgraded to 4.3 (so far)

Kathy (and others out there) you may want to take a moment to remove breakable stuff off of your edges of dressers, etc. If you have those little stand up picture frames, lay them down flat, and things like glasses/cups in your cupboards, you may want to place them further back or lower....I know you folks are nervous as heck as it is with the movement, but adding to a larger sudden jolt knocking stuff down and breaking it is not going to make things any calmer.
Also if you have some prised large glass framed pictures hanging on the walls, it may be best to remove them for the time being and set them safely against the wall. Take care of anythng that may fall on your heads while you are laying or sitting....and by all means know where and how to shut off gas, etc IF something very disturbing happens...Let's hope the rockin and rollin at least gives you guys a few hours break. Someone get some sleep while another stays up and pays attention.

Our thoughts and hearts are with you.

Here's a pretty close Helicorder...

Ferguson Farm I assume, Westcoast?? Or have you downloaded another network that's better?

I apologize I was looking at the square symbols I forgot to click it I got 4.3 as well

I actually didn't even need to download any. They were all available...here are the best ones:

TA.U40A

TA.V39A

TA.X40A

Those are all just to the left and below the epicenter showing in AR right now

Got those - just wondered if there were any other networks in the area.. will check.

westcoast-any idea why usgs reported the epicenter originally near keiser then moved it to the area of Guy?

I just noticed that TN had a quake this morning too. Hopefully this won't be a trend.
