USGS Study Connects Earthquake Risk To Wastewater Injection, Fracking Advocates Say, "Who Cares?"

A new study out in Science by US Geological Survey scientist William Ellsworth links earthquakes to wastewater injection sites. These earthquakes, thought to be caused by pressure changes due to excess fluid injected deep below the surface, are being dubbed “man-made” earthquakes.

It's not the first time scientists have used that moniker, as earthquakes have been associated with other industrial operations that mess with underground formations such as surface and underground mining or dams that impound water into reservoirs.

Yet, in more recent years, we're seeing more and more of them,

“The number of earthquakes has increased dramatically over the past few years within the central and eastern United States. More than 300 earthquakes above a magnitude 3.0 occurred in the three years from 2010-2012, compared with an average rate of 21 events per year observed from 1967-2000.”
 

 

 


Many likely know that “wastewater” is a byproduct of many fossil fuel processes. It can come from raw material itself or is a leftover from purification steps during the extraction and processing phases of fuel production.

Toothpaste More Dangerous Than Fracking, "Expert" Says

It's okay, people. We've been blowing this whole fracking thing way out of proportion. Dr. Barry Stevens of TBD America sets the record straight in hopes that we'll re-align our focus and concentrate on the real issues at hand, which, by the way, is not fracking (Spoiler Alert: it's toothpaste).

Over at OilPrice.com, Dr. Stevens has provided an exhaustive retort to some “environmentalist” who posed the question, “if hydraulic fracturing is so safe, why do drilling operators working in Pennsylvania’s Marcellus Shale Play dispose the backflow out of state in Ohio?”

Let me summarize some of Dr. Steven's salient points for you:

Earthquakes really aren't that big a deal.

“…injection well seismicity typically ranges from 1 to 4 on the Richter scale and rarely cause damage.”

Sure, Youngstown, Ohio, where the earthquakes happened, may have never had them before, but that doesn't mean anything. The State Representative there is just going way overboard in calling for an indefinite moratorium there. The citizens should really be thinking of it as a free city-wide massage. Besides, the D&L Energy said it will be conducting its own investigation. I’m sure they’ll find it’s nothing to worry about.
