the oklahoma quakes have slowed to a trickle and one has to wonder if so have the injections of fluids into wells in the area. (for the safety of the equipment, of course. ) anyway, i finally found a mention of just how many wells that might be in the area of the swarm. earthquake prediction -like earthquakes themselves- always takes place between the hammer & the anvil.

Fracking may be to blame for Oklahoma earthquakes

According to the Associated Press, there are 181 such injection wells in the vicinity of Saturday’s Oklahoma quake and Sunday’s aftershocks. AP also reported Oklahoma typically only experienced about 50 earthquakes a year until 2009 when that number spiked dramatically. Last year there were 1,047 small quakes in the area, prompting the installation of seismographs.

The U.S. Geological Survey (USGS) is now seeking more data on the weekend quakes in Oklahoma, a state whose panhandle region borders southeastern Colorado, where earthquakes this summer shook area residents in an area with natural gas drilling.

In August, Las Animas County, Colo., experienced a 5.3-magnitude quake, followed by a 5.8-magnitude quake in Virginia that was felt in Washington, D.C. Those quakes also prompted questions about fracking operations and injection wells.

“That process can cause very small earthquakes, but the fracking process doesn’t really, we think, induce large earthquakes,” USGS scientist Mike Blanpied said in a video chat at the time. “The thing that can induce larger earthquakes is the high-pressure waste fluid injection that’s done in some places.”
...
"Just to be clear, the connection between fracking and fluid injection and earthquakes is an area of active research and really we’re only starting to learn about how those things are connected,” Blanpied told reporters in late August.

The USGS points to Colorado for the most infamous case of an injection well being linked to an earthquake. The U.S. Army had been disposing of toxic fluids up to 12,000 feet underground at its Rocky Mountain Arsenal near Denver but had to shut down the well after a 5.5-magnitude earthquake and several aftershocks.

usgs has a new side-bar faq on earthquakes caused by injection wells. i am quoting just 1 of the 9 questions they have covered.

FAQs - Earthquakes Induced by Fluid Injection

USGS said:

...
Q: Are earthquakes induced by fluid-injection activities always located close to the point of injection?

A:

No. Given enough time, the injected fluids can migrate substantial horizontal and vertical distances from the injection location. Induced earthquakes commonly occur several kilometers below the injection point. In some cases, the induced earthquakes have been located as far as 10 km (6 mi.) from the injection well.

then there is the matter of geothermal plants and quakes. just noticing quite a swarm of quakes the last few days in the immediate environs of the geysers geothermal generating complex.

i saw that. a 5.6. if you felt it you can contribute to science by reporting it here. >> Did You Feel It?

This site has potential fracking areas, meaning there is venture speculation in these areas. It also shows where there have been fracking with negative results on nearby communities. Aside from the fact that we know this does damage that could cause catastrophic events, it may tend to confuse studies about global warming. Notice one of the venture speculation areas is in the Yellowstone area. I mean... I mean... they've got a lot of damn gall. (Of course I'm a French guy, so I've got a lot of Gall, too )

mon dieu! excellent page. i see oklahoma has evaded inclusion on that map. while i did find that there were injection wells near the quakes i have been reporting on, i can not find if that work was suspended coincident with the quakes subsidence. (all geologic puns intended. )

for easy viewing, here's the map from your link:

This page and the map may predate the Okie event. Oui. Allons donc, Mon Dieu! Is it any wonder people are concerned about the park caldera?

looking at the detailed descriptions of the 2 "fraccidents" nearest the park, it is air & groundwater pollution that resulted from fracking in Wyoming. given the frequent normal quake activity in the park i think it would be difficult to connect nearby fracking with any quakes there. even if there was an eruption in the future it would be a tough call and in that case the cause would be far down the list of concerns.

just a clarification that it has not been a single "event" in oklahoma, rather a series of quakes. whether these quakes constitute a "swarm", which is a series of quakes where later quakes are larger than the initial one, or a multiple "shock-aftershock" series wherein later shocks are smaller than initial ones, is arguable. the quakes haven't stopped altogether, whether or not the nearby fracking has.

in case you missed it, the usgs quake preparedness site currently has an faq sidebar on the fracking/quake correlation. >> Frequently Asked Questions Concerning Earthquakes Induced by Fluid Injection
