Stunning evidence of a Caldera volcano in Arkansas! Must read!

PIN

Increase in magnitude and becoming more shallow. What does that tell you?

I am not convinced that all of these recent earthquakes in Arkansas and Oklahoma are from fracking. While studying the geology of the region I noticed something interesting. There is a pattern starting to form suggesting that the recent earthquakes are a result of increasing volcanic activity. You are probably thinking, if there were a volcano in Arkansas we would know about it. Although unproven and highly speculative, the following information shows evidence of active volcanism in the state of arkansas. I plotted all of the evidence I found on google maps and may have found the reason for the recent rise in seismic activity. The map is at the bottom of the post.


First and foremost I would like to point out The hot springs National park south of little rock

[link to www.nature.nps.gov]
the hot springs are located above the western edge of a large pluton (an igneous intrusion) with an upper surface about 4,000 feet below land surface that extends eastward from an igneous outcrop near Magnet Cove (fig. 1). Bergfelder suggests that the meteoric water percolates through a fracture zone (location unspecified) associated with the margin of the pluton and then (because the heat source is unknown) either takes in heat from the pluton, percolates below the pluton to depths of about 8,000 to 12,500 feet and takes in heat, or percolates below the pluton to a lesser depth and takes in heat from underlying magma. The Bigfork Chert and the Arkansas Novaculite outcrop areas, which may serve as recharge areas, primarily lie north and northeast of the hot springs (Bedinger and others, 1979).
This area is teeming with evidence of volcanic activity. one example is called Magnet cove.It is consisted only of Igneous rocks which can only be formed by volcanic activity.
Cove. [link to www.rockhoundingar.com]

"Magnet Cove is a 100-million-year old igneous intrusion (mass of igneous rock) of some rare and unusual rock types - all derived from a melt that was originally a CO2-rich basaltic liquid in the earth's upper mantle. The intrusion's piercing style resulted in a steep, near vertical contact with the country host rock, Paleozoic shales and novaculite. It is likely that the intrusion never reached the surface. Only one geologist in the 1930's described anything like a vent. It is probable that what he described, though volcaniclastic in appearance, was a steep-walled breccia pipe or explosion zone as has been noted in the smaller pipe at Potash Sulphur Springs." Magnet cove is a type ring complex, or ring dike, found commonly at the center of a volcano. [link to en.wikipedia.org] [link to en.wikipedia.org]
Next, there is Potash sulphur springs which also contains uranium. [link to vulcan.wr.usgs.gov]
"Arkansas's Uranium:1
In Arkansas, several uranium anomalies were discovered during the 1950s.The Potash Sulphur Springs igneous intrusion in Garland County is probably the best known and perhaps the first site where uranium was discovered in Arkansas."
Novaculite is also found in the Hot Springs area."Novaculite is the rarest and finest abrasive stone in existence". This mineral is only found in two places in the world, Arkansas and in the Marathon Uplift in west texas. [link to en.wikipedia.org] [link to www.danswhetstone.com] [link to en.wikipedia.org]

Finally the strangest place in this volcanic area is called "Hells half acre". It is a small area of land in the middle of forest where nothing can grow and animals, even hunting dogs will avoid. Apparently it is believed by some people that "the devil lives down there" [link to www.hsnp.com] Picture: [link to commondatastorage.googleapis.com] Notice that the trees surrounding the area are all dead. This suggests that some kind of activity is producing something very toxic.

More evidence of a volcano lies in the northeast corner of the state that is directly connected to the New Madrid fault called Crowley's Ridge.
The ridge is primarily composed of sediment as loess. It contrasts greatly with the flat table land around it and with the black soil that makes up the delta. It varies from half a mile to 12 miles (19 km) wide and reaches an elevation of 550 feet (170 m) near its northern extremity. There is evidence that the area's elevation has increased over the years, suggesting that uplift took place and is still taking place. This alternative explanation posits a link between the ridge and the nearby New Madrid Seismic Zone."[1] [link to en.wikipedia.org]

Since there is evidence that this area is still rising in elevation, it may be the ridge to the caldera.
[link to en.wikipedia.org] "If the magma is rich in silica, the caldera is often filled in with ignimbrite, tuff, rhyolite, and other igneous rocks. Silica-rich magma does have a high viscosity, and therefore does not flow easily like basalt. As a result, gases tend to become trapped at high pressure within the magma. When the magma approaches the surface of the Earth, the rapid off-loading of overlying material causes the trapped gases to decompress rapidly, thus triggering explosive destruction of the magma and spreading volcanic ash over wide areas. There is a type of lava in explosive calderas called A'a. Further lava flows may be erupted. If volcanic activity continues the centre of the caldera may be uplifted in the form of a resurgent dome". Arkansas ranks first in production silica, producing one half of the worlds supply. [link to www.arkansas.com]

This site from USGS states that The Arkansas delta sloped west toward the mississippi river and south toward the Gulf of Mexico at a rate of 0.5 feet per mile. [link to pubs.usgs.gov]
"The land surface generally slopes toward the Mississippi River from both the eastern and western sides of the Study Unit and to the south toward the Gulf of Mexico."
So far facts show that we have a ridge, a dome-like valley sloping east, west and south, and the most silica in the world, Not to mention much of Arkansas is in a Rift valley. All of this points to the area being an explosive Caldera.
This is Reelfoot rift. [link to upload.wikimedia.org]
To tie is all together I plotted all of the recent earthquakes in Arkansas and Oklahoma along with certain hot spots in the state and found a disturbing pattern.

[link to maps.google.com]
Notice that even though the quake in Guy, Ar, it lines up directly with the earthquakes in Norman, Oklahoma through an area known as the Arkansas River Valley.


And to conclude, we may be fucked...Or not. Enjoy!

Fuck OP this place was on Ghost hunters and the friggin hole they showed creeped me out and I completely 4got about this. Pray for Arkansas this may very well be the next catstrophe. Just imagine so many people not even aware of the danger

Nobody mentioned the "new" Marianna fault. I've read that liquid sand is bubbling up...?

actual research rarely gets pinned

True fact, Calderatard (sorry, just had to use the term once).

Excellent post, thanks!

Interesting about so many people not being aware of the danger. Yesterday I watched the John Moore video saying Arkansas is where all the Navy officers retire too. Because they think it is safe. Maybe they know something or maybe they don't.

Pin for relevance and Interest

Anybody heard in updates on activity?

I just checked Arkansas AGS website and I don't see anymore earth quakes. Maybe they just haven't updated in while. The Guy, AR swarm has been active everyday for months going on a year, now it is quite. Why does that worry me?

[link to www.geology.ar.gov]

I am normally a skeptic but i must say this is a very interesting and well thought out theory. I agree that is rare to find "hot springs" anywhere in the world that are not associated with some sort of volcanism....Iceland, Yellowstone, Africa, etc.

Keep up the good work!

This is my favorite thread on this site. So much GREAT info. Thanks!

3.0 in AR today, along with a few in the 2.range.

Check out this current 4+ Swarm Activity at the direct Location of an Ancient Caldera just off of the Texas Boarder!!..

Thread: !!ALERT!! - 4+ Activity In Ancient Caldera Off the Texas Boarder!!

Check out both links provided esp. the USGS and see that there is no Historical Seismicity in that Location what-so-ever!?

Dodgy..keep your eyes on this one Folks!!

Cheers!

No shit! where was the damage to the house? Foundation? So dudeman lives in ozark? That's right around where the Ozark Plateau transitions into the river valley... I have not felt or heard anything since a couple months ago, knock on wood!I think its pretty safe up here in the far northwest region, the ground is built like a brick shit-house lol. Mostly limestone mixed with tons of red clay. The only worry would be the Karst systems failing and collapsing which would really, really suck...
