OT: Increased Seismic Activity in AR Past Week

[Wildwood]

WOW!! Absolute destruction. They must be drilling for gas close to that area. Has FEMA stepped in yet? I bet they will give out those cool blue 20x100' tarps. Grab one if you get a chance.

I've started a prayer chain for those poor folks in the disaster area. Let me know when the Red Cross shows up. I'll bring 'em some of that special Koool-Aid.

Thanks for your prompt report of this natural disaster.

More oddness today...some type of tremor or shock wave was felt from Alaska to S.C. It took just 20 minutes to travel 2000+ miles.

Vernon,

When Marlo and I flew to Anchorage Alaska a few years ago, afterward I was trying to compute the road mileage back there and it seemed like about 5000 miles from Benton :) I have never gone to a place before that I would have to think about it it terms of how many oil changes I would need to make. Or how many weeks it would take me to drive it in my old truck...Of course, I always like to take the scenic route


Best Regards

Jim,

Meant 4k instead of 2, this is the distance between Eagle, AK and New Hope, SC. So it moved about 13k per hour.

Seismic waves travel at the speed of sound in whatever rock or material they're passing through. That's usually somewhere around 7 to 8 km per sec (http://hypertextbook.com/facts/2001/PamelaSpiegel.shtml" onclick="window.open(this.href);return false;). Converting to miles per hour, that's in the 16,000+ mph range. So a 12k or 13k mph wave probably isn't unusual.

This has been one of the more interesting threads I've read in a long time. I would love to know more about "Hells half acre", sounds interesting, and may warrant a trip to see it, any info would be appreciated.

Crowley's Ridge is an Erosional Remnant. The ancestral Mississippi and Ohio Rivers scoured away the former ocean bottom on either and deposited deep layers of soil from the upper midwest in its place in the Delta but they skipped over the Ridge - possibly due to an uplift that's part of New Madrid Seismic zone - and the Ridge became a gravel bar of sorts between the rivers that then caught wind blown glacial dust (loess). You can find marine fossils (oyster shells) in the bank and creek bed of Crow Creek south of Forrest City. Eventually the Mississippi cut through the Ridge and moved east of it. The uplift theory is contested by many geologists - but the Ridge is still rising every so slightly.

I've added it to my "go see" list also. It surprised me how hard it was to find out where the heck it was - you'd think a google search would yield multiple hits with GPS coordinates, but it didn't. Postcards, pictures, blog discussions, you name it, just not the location except in very broad terms. Maybe google isn't hitting the geocaching databases, because surely there is a cache there somewhere.

Anyway, I finally tracked it down via a road description of how to get there, combined with the fact that you can see the rock field on Google Earth.
It's at N34.5341 W92.9966

Cut and paste those coordinates into Google earth or your favorite aerial mapping site if you want to take a virtual look.

Cowper, thanks for the info.

What's going on off the coast of Yemen? What started yesterday with 40+ quakes from 4.6 - 5.4 all around the same depth is ongoing today and getting much deeper :shock:

[Wildwood]

HAARP??????????????????? :shock: Ya never can tell about these things . . .

Didn't CERN crank up a few days ago? http://www.cerntruth.com/?p=105" onclick="window.open(this.href);return false;
:shock:

Rember back in the spring of '08, wasn't there was a swarm of hudreds of quakes off the coast of Oregon?

Here's something that will spook all of you around the Greers Ferry dam & It's proximity to the seismic activity:
