Arkansas Earthquakes Could Be Man-Made

oxide7 writes "The small earthquakes that struck north central Arkansas could be from a combination of natural and man-made activity. Some experts think that pumping water into the ground as part of the extraction process of natural gas could cause local seismic events."

      In Colorado in the 1960s, the Rocky Mountain Arsenal used a ~12,000 ft. deep dry well to inject toxic waste related to chemical weapons the army was manufacturing. There was a bizarre spike in activity and magnitude starting not long after the well was put in service, which continued for about a decade after they stopped injecting the waste, and actually started pumping some back out. There were a few magnitude 5+ quakes, which caused structural damage in the Denver-Boulder metro area.

      It could be mere coincidence that seismic activity spiked right about the time the well was put in service, but how likely is that, really? I know, correlation and causation and all, but it was serious enough that folks who lived around here back then still talk about the tremors, and there haven't been any events like that in recent decades. Some of those who remember tend to freak-out at any mention of starting injection recovery in the gas fields north of Denver.

      Maybe any gas companies who want to do the hydraulic extraction should pay for any and all damage that appears to correlate to their activity? Arkansas would be a good choice for a study, they'd just have to hire a fleet of trucks to tow the mobile homes back to their pads when they done get shook off and roll down into the holler.

      For an even more impressive example, read about the Vajont Dam in Italy.

      http://en.wikipedia.org/wiki/Vajont_Dam

      An engineering marvel for its time, the dam was built based on shoddy geology - there was a faultline running up one side of the adjacent mountain. In a nutshell, filling up the dam forced water into the fault, which eventually caused half the mountain to fall into the dam. The dam was well built enough to not break - but the water spilled out over the top and killed about 2000 people.

      However, the hand-wringing of the article is a bit unwarranted. It's well known that pumping stuff in and out of rock is bound to cause seismic instabilities. Magnitude 4-5 stuff (assuming they mean moment magnitude? They don't say) is generally considered small fry.

    Magnitude 4 seismic events are of relatively little concern, in the scheme of things; but the water pollution that has resulted is more serious.

    There is a more serious governance/philosophical issue at work, though. These sorts of energy extraction operations, whether they be hydrofracking gas, doing the assorted horrid things required to get tar sands and oil shales flowing, or mountaintop removal, all involve the extraction company imposing (often quite significant, sometimes fatal) externalities on the people in a broad swath around them. Generally, these externalities are not compensated. That's how pollution goes.

    When a price needs to be paid, two things matter: "How big is it?" and "How will it be allocated?". At present, while the jury may still be out on the size of the bill, the method of allocation appears, at first approximation, to be "Suck it, peasants, costs will be imposed as is most profitable for your betters!".

    Such a cost allocation scheme really ought to have no friends anywhere on the political spectrum. The reasons for liberal opposition should be so obvious as to no need mention. For conservatives or libertarians, such rampant imposition of externalities on other people's persons and properties should be recognized as making a mockery of man's right to person and property, and the state's legitimate role in preserving the same.

    We must be careful that, in attempting to break our dependence on kleptocratic energy-despotic hellholes, we do not allow ourselves to become one...

    There are two problems. One is that people in the aggregate is easily led, this hardly bears further discussion in the context of this conversation. The other is that the real voters, the people with money, are the ones who are imposing the externalities. It's all gravy to them. So long as the ability to make decisions is concentrated in these individuals the decisions can only be selfish.

    Uh, that "philosophy" is not something anyone espouses. It is something people DO, while saying something different. Libertarians reject government regulations, such as environmental regulations. Yet they claim to want government to protect their person and property, as that is the only fitting role for government, providing police and an army. Well, how do you protect people's health and property from negative externalities like pollution without environmental regulations? Do you see, libertarians CLAIM they want government to protect people from assault, but they don't. Pollution is assault. It harms health and property, yet libertarians do not want government to protect you from THAT kind of assault. They want to be free to assault you in any possible way, without interference. When libertarians claim government has a monopoly on violence, what they really means is, "I wish I could use violence to get my way."
