Must have, the piece I read was only a few months ago and was based on recent research.

Latest Swarm Of OK Earthquakes Could Be Tied To Lake Arcadia

Guess that overtakes 50 yrs. of research?


Scientists Say Oil Industry Likely Caused Largest Oklahoma Earthquake

The largest recorded earthquake in Oklahoma history was likely triggered by the injection of wastewater from oil production into wells deep beneath the earth, according to a study published Tuesday in the scientific journal Geology...

Not the piece I was talking about but some of the same info,

An interesting piece, we have three possible causes in OK, water wells, injection wells, and the lakes.

If I were to bet it'd be on the injection wells not the fracking itself.

Depends on who is doing the research and what their agenda is. I really wish I could remember where I read that piece from the USGS. It did a pretty good job of explaining why most of OKs earthquakes are not from injection wells.

The research I cited was from the USGS and the Army, here's something newer from the USGS,

Man-Made Earthquakes Update

Although it may seem like science fiction, man-made earthquakes have been a reality for decades. It has long been understood that earthquakes can be induced by impoundment of water in reservoirs, surface and underground mining, withdrawal of fluids and gas from the subsurface, and injection of fluids into underground formations...

Search the USGS web site. You'll be dissapointed.

USGS Newsroom 10/22/2013

The analysis suggests that a contributing factor to the increase in earthquakes triggers may be from activities such as wastewater disposal--a phenomenon known as injection-induced seismicity. The OGS has examined the behavior of the seismicity through the state assessing the optimal fault orientations and stresses within the region of increased seismicity, particularly the unique behavior of the Jones swarm just east of Oklahoma City. The USGS and OGS are now focusing on determining whether evidence exists for such triggering, which is widely viewed as being demonstrated in recent years in Arkansas, Ohio and Colorado.

There are articles in there under the heading "Science In Your State"
If you look at Oklahoma, "drought" is an issue and "earthquakes" is an issue.
I haven't seen anything (yet) that suggests that the second issue is caused by the first issue.

I don't think they've come to any final conclusions about injection wells either, though.

Holland commented that science has already shown that, in rare instances, injection wells, even hydraulic fracturing, can cause earthquakes, but, up to now, very small ones...

Just heard from a friend, that people in Derby, KS felt it there as well.

The sheer arrogance of these scientists to believe that we have anything to do with tectonic change.
