Conspiracy advocates and 2012 doomsdayers just got more fodder for their predictions with an unusual 4.0 earthquake shaking Ohio this past weekend.
The earthquake itself isn't what's raising eyebrows, though; it's the apparent cause: pressure from a wastewater injection well used by fracking companies.
This isn't the first time we've heard this is possible, but it's grabbing headlines now.
Just the facts
It seems that the problems aren't necessarily from the fracking process per se, but the disposal of the fluids used in the process. According to The Christian Science Monitor, "At issue is the effect fluids injected at high pressure can have on faults. The billion-year-old 'basement' rock that underlies much of the eastern US is laced with faults."
At the request of the state of Ohio, Northstar Disposal Services -- the operator -- has closed the well while the situation is studied more closely.
This situation isn't limited to Ohio. Earthquakes shook Oklahoma last year, and with major players Chesapeake Energy

What this means
For those invested heavily in natural gas, there may be some solace in the fact that the fracking process itself isn't to blame. It seems that the fluid being used in fracking -- which itself has raised environmental concerns -- needs to be disposed of in ways that won't cause the earth to rumble.
It remains to be seen whether simply adjusting disposal methods can solve this, or if it will require a more intensive solution.
Because certain chemicals are added to the water being used in fracking, disposal itself can present a sticky situation. Though some companies -- such as Range Resources
Whom this effects
Let me be clear, it's far too early for anyone to start proclaiming that the sky is falling for natural gas companies. But if the recent quakes, questions about fracking solutions, and the effects of their disposal continue, this could create a real problem for both investors and the larger energy industry in America.
Beyond the obvious natural gas extractors such as Chesapeake and SandRidge, there are several peripheral companies that are counting on natural gas to power our future. Westport Innovations
