Ohio's temblors linked to fracking

I'm not sold on fracking. I think the dangers are downplayed. Here's a case in point.

COLUMBUS, Ohio -- Geologists in Ohio have for the first time linked earthquakes in a geologic formation deep under the Appalachians to hydraulic fracturing, leading the state to issue new permit conditions Friday in certain areas that are among the nation's strictest.

A state investigation of five small tremors last month in the Youngstown area, in the Appalachian foothills, found that the injection of sand and water that accompanies hydraulic fracturing, or fracking, in the Utica Shale may have increased pressure on a small, unknown fault, said Rick Simmers, state oil & gas chief. He called the link "probable."

While earlier studies had linked earthquakes in the same region to deep-injection wells used for disposal of fracking wastewater, this marks the first time that tremors in the region have been tied directly to fracking, Mr. Simmers said. The five seismic events in March couldn't be easily felt by people...

...A U.S. government-funded report released in 2012 found that worldwide, two instances of shaking could be attributed to actual extraction of oil and gas, as opposed to wastewater disposal in the ground -- a magnitude-2.8 quake in Oklahoma and a magnitude-2.3 quake in England. Both were in 2011.

Later, the Canadian government tied quakes in British Columbia's Horn River Basin between 2009 and 2011 to fracking. Those led to stricter regulations, which news reports indicated had little effect on the pace or volume of drilling.

Obviously you don't understand earthquakes. Few people would even feel a 2.8, and about 1000 occur every day throughout the world. Also, stress in the earth's crust builds up over time, and since multiple small quakes relieve the stress, they make it less likely than a larger one will occur later.

Lol, too funny. A name change because I thread-banned you. Thanks for reminding me to be more careful the next time.
 
You can always pull a Zippy and whine to the moderators, having this moniker banned as well.

But that won't change the fact that these small quakes are meaningless regardless of what causes them, another fear tactic of The Left because they want the US to be dependent on the ME for its energy.

And a series of small quakes can't contribute to weakening the foundations of buildings?

Earthquakes under 3.0 are rarely felt by people and cause no damage to buildings. There are around a million a year worldwide. Bear in mind that it is a logarithmic scale, an earthquake that measures 5.0 on the Richter scale has a shaking amplitude 10 times larger than one that measures 4.0, and corresponds to a 31.6 times larger release of energy.

What are the possibilities that a larger quake can occur in an area where temblors already did? Look at the San Andreas Fault, I believe there have been temblors in sections of it.

A few years ago there was a 5.8 quake near Richmond, VA. That's close to 350 miles from here and we not only felt it but I've got new ceiling and wall cracks as a souvenir!

As I've already said the Richter scale is logarithmic not linear, that was a real earthquake as opposed to a 2.8 which is more akin to a herd of elephants passing wind in comparison. I wonder how many earthquakes have been caused by coal mining down the years?

For some reason earthquakes on the eastern seaboard are felt much more strongly than here on the Pacific. Of course, we are capable of getting rolled over by 9.0+ blasts...

I was looking this up and the explanation referenced "geologic structure and rock properties that allow seismic waves in the East to travel farther without weakening."
 
Obama signed legislation on cracking that would be massive greenhouse gas reducers!
Because he knows green energy.

I have friends in Jersey (near Giants Stadium) who needed me to do 2 ceilings after that quake. Of course, their house is old, and still has plaster/lath.

Yeah that was an interesting day, I live in Richmind. We had a chimney in an historic house under the epicente in Mineral north of Richmond lose some bricks and messed up an elementary school pretty good. An interesting comparison of the nature of construction quality then and now. But Iwas surprised after another earthquake several years earlier to learn there were hundreds of quakes every year in the Old Dominion. Makes me wonder how many quakes Ohio experiences a year on average and if its > zero how they know fracking was responsible. That being said, areas with known bad faults ala San Andreas should be off limits just to be on the safe side. Well unless you see LA falling into the Pacific as something of a positive....
