Reelfoot will finish up eventually. That is the underlying issue for the nmsz. Here's a little background.

The really scary part is that it connects across Arkansas to the Oklahoma region that they are pumping the fracking water into. Most of the data and maps are split across individual state websites and it is hard to find one to correlate all the info into one map. Here's one that shows the underlying connection.

This one has some good graphics. The underlying ground in the reelfoot contains a lot of sand. More reason to be disturbed by the fracking.

Shout out to Spirit Warrior. She was the one that got me looking into the connection with all of her posts on the OK fracking.
Quoting: Gomez Awe...
shout out back to you Gomez. I hope all is well with you.
Here is some more information concerning Oklahoma earthquakes that you or anyone else may find interesting.
USGS: Oklahoma has
'unheard of' seismicity that might produce 6.0 quake, but Cushing efforts indicate problem is manageable
Several fault zones appear capable of 5- or 6- magnitude quakesThe magnitude-4.7 quake near Cherokee early Thursday was the state’s largest since one of Prague’s aftershocks in 2011. The main event and the state’s largest recorded earthquake was a 5.6-magnitude temblor that struck Nov. 6, 2011.
***VERY CONCERNING STATEMENTS MADE HERE:McNamara described the
number of magnitude 4s in 2015 as “unheard of in any other similar-sized region on the planet that we know of.” He explained that scientists see similar sequences or numbers associated with large earthquakes such as those in Nepal and Japan.
What is “very strange” about Oklahoma is the number of magnitude 4s distributed over several different faults with no large quakes associated with them, he said.
“Now we have as many as 13 different fault zones in Oklahoma with magnitude 4s occurring on them this year alone,” McNamara said. “And so just from the behavior of the Prague sequence, any one of these looks like it could produce a 5- or 6-magnitude earthquake, so we’re very concerned about a number of these fault zones.”
**THE UNKNOWN IN REGARDS TO EARTHQUAKES VERY SCARY: Recent quakes highlight faults unknown to scientists. McNamara noted that the recent magnitude-4.7 temblor near Cherokee on Thursday and the 4.3 close to Fairview on Nov. 15 illustrate yet
another challenge.
Both appear to be on faults previously unknown to the U.S. Geological Survey.He said unmapped faults present difficulties in determining the maximum magnitudes that can occur on them and where the quakes could strike, as well as whether they are isolated or connected to larger fault structures.Industry warns of economic tolls. The industry is collectively acknowledging some ownership of the problem, although it warns that
“states should avoid drastic measures that are fueled more by politics than sound science, including blanket bans on injection wells.”

More than 635 Oklahoma disposal wells directed to reduce depths, volumesOklahoma oil and natural gas producers have long targeted the deep Arbuckle layer as a favored location for getting rid of the briny "fossil water" that comes up with oil and gas. But as the state deals with a huge increase in earthquakes, regulators are focusing on the links scientists have made between the amount of wastewater disposal into the Arbuckle and man-made earthquakes.
Oklahoma oil and gas producers inject wastewater into other formations, but by far the largest volumes — more than half — go into the Arbuckle. The total volume disposed into Arbuckle layers in 2014 would more than fill Norman's Lake Thunderbird.
SandRidge accounted for about one-third of all the produced saltwater disposed into Arbuckle zones in 2014, according to an analysis of volume data from the Oklahoma Corporation Commission.
That alone is enough produced saltwater to fill Edmond's Arcadia Lake.
Most of those volumes went into SandRidge disposal wells in Alfalfa, Grant, Garfield and Woods counties. Those counties are also where the number of earthquakes greater than 3.0-magnitude has increased in the past few years. The counties are among dozens targeted by regulators for reduced volumes or depths for saltwater disposal wells.
A very good article. A lot of detailed information about disposal rises and data updates. Check out the link below
