Ohio lawmakers have put a temporary ban on fracking after experts say it is certain that recent fracking in the Buckeye State caused an outbreak of earthquakes.

According to some seismologists, hydraulic fracturing, or fracking, is to blame for a string of tremors in Ohio, including a 4.0-magnitude quake on New Year’s Eve. It has long been suggested that fracking, which involves deep-earth drilling to extract gas for natural resource reserves, has been culpable for quakes. In the fracking process, wastewater collected during the deep drilling is injected back into the Earth for disposal. Thought to be safe by some, other experts insist that the brine water could find its way into subterranean faults and force parts of the planet to separate. The Youngstown, OH area has seen 11 small quakes since last spring, and now a moratorium has been instated in the area to keep future fracking from occurring while seismologists reinvestigate the quakes.

Even with a stay in place, however, experts say the quakes won’t be stopping anytime soon.

"The earthquakes will trickle on as a kind of a cascading process once you've caused them to occur," John Armbruster of Columbia University's Lamont-Doherty Earth Observatory tells the Associated Press. "This one year of pumping is a pulse that has been pushed into the ground, and it's going to be spreading out for at least a year."

Ray Beiersdorfer, a geology professor at Youngstown State University, adds to the Business Journal, “I wouldn't be surprised if it continued for a year or so."

Regulators in Ohio have asked D&L Energy Inc., a company that carries out fracking near Youngstown, to stop injecting waste water back into the Earth while an investigation is opened up. Another quake of 2.7 magnitude occurred on Christmas Eve and prompted state officials to step in less than a week later. Had regulators not recommending the halt, D&L could have continued to operate fracking wells — and only a day before the moratorium was instated they submitted permit applications in hopes of beginning drilling in a residential neighborhood just outside of downtown Youngstown.

The Ohio Department of Natural Resources says that by D&L injecting wastewater more than 9,000 feet into the Earth, the onslaught of quakes were caused by human action. Officials in other areas of Ohio area considering stopping drilling in the interim as well.

In all, there are 177 wells used by fracking operations in the state.

The D&L company first began their own drilling in December 2010 and seismologists say the fracking has yielded nearly a dozen quakes as a result so far. Since fracking began in all of Ohio in 1985, around seven million barrels of wastewater have been injected in the Earth.

"We fully support the decision of the Ohio Department of Natural Resources to issue a temporary suspension of five injection wells in the Youngstown area," Thomas E. Stewart of the Ohio Oil and Gas Association adds to the Business Journal. "It was the correct course of action to ensure the safety and peace of mind for area residents."

The tremors we get from gold mining are bigger than that. Shall we stop that too?

Yes. It will only greatly harm the economy and cost thousands of jobs.

Reminds me of this quote:

GEORGE WILL: You referred to the Hoover Dam, great achievement of the '30s. You couldn't build the Hoover Dam today because they'd discover a snail darter in the Colorado River and would stop it.
 
The problem with the area they want to frack is that it is a huge area of ecological beauty.... plus its almost in the area of the SKA...... I would rather have the SKA and keep the area as it is, than have these idjits fracking in the area.
 
We need energy sources, so it's not a question of whether we extract, but making sure we do it in the safest cleanest way we can.

Richter Magnitudes
4.0–4.9: Noticeable shaking of indoor items, rattling noises. Significant damage unlikely.
Like living next to a railway line.

You don't want anything more than that, so it's worth keeping an eye on it. But cheap energy is good.
 
I always thought that there was a fault line running from Bloem to Cape Town, the one that goes through Koeberg power station... ??

I see nothing

If there IS one, I think this fracking would be a bloody stupid idea.... :confused:
 
There are some yes...

There is the milnerton fault line about 8kms offshore from Koeberg.
 
Actually if you go onto Google Earth you can see "roughly" what looks like a fault line that seems to run from Pretoria down to CPT... and also branches out through Lesotho...

Granted this is a roughy correlation based on about 15 earth quake sites listed.... but still...

The CSIR (1988 – 1994) did lots of studies concentrated on attempts to inject water onto known active fault surfaces in order to induce seismic slip. All these studies have shown that pumping water onto faults will induce slip and result in some seismicity.

However, the induced seismic events were not of major magnitude mainly because water is too viscous to pressurize a large enough area on the fault.

What worries is people who say "fracking is safe". I rather people say "fracking may increase the seismic risk, however, the consequences are low and maneagable"

I've stayed in Klerksdorp for almost 10 months, 4.0 quakes occur there almost every day, you get use to it. The room and everything starts to shake.

That's really what safe means. There's not much, if anything, in life that can be declared 100% free of risk. That's why the safety madness that currently grips society is so silly.

I agree, the seismic stuff is actually not a massive problem (in my opinion) with fracking.... it might mean a few more earthquakes of the normal magnitude that the fault already produces....

For me personally, what does worry me about fracking is the chemicals they use, and the ecologically sensitive area they plan on doing the fracking in...

Also there is a hint that allowing fracking COULD hurt our chances of getting or running SKA effectively, and I think SKA is much more important for this country in the long term.

The long-term effects are critical and often neglected. e.g. Acid Mine Drainage was an issue 50 years ago but effectively down played to suite certain business and political agendas. Look at what we have now.
 
Yup fracking can be done with water
 
Can be done, yes.. but the question is would they actually do so?

And if it can be done just with water, then why do they use all those nasty chemicals?
