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."

      TFS quotes "Some experts think that pumping water into the ground as part of the extraction process of natural gas could cause local seismic events." but leaves out the next sentence from TFA "But the area hasn't been studied enough, they say, to know for sure."

      Then, TFA gets it wrong by claiming "The scale is logarithmic, meaning a magnitude 5 earthquake is 10 times as powerful as a magnitude 4" when in reality the amplitude of a magnitude 5 earthquake is 10 times larger than a magnitude 4, and the energy released is roughly proportional to the amplitude raised to the 3/2 power, so a magnitude 5 earthquake will cause more than 31 times the destruction than a magnitude 4 earthquake, 9depending a little on how long each lasts), The earthquakes observed were not out of line with past experience in the area and were too small to be of concern by themselves.

      Pumping high pressure water into active fault lines might not be such a good idea, but you are unlikely to find gas or oil in a fault, since the cracks in the rocks give a path for the fluids to escape and rise.

      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?

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.

Generally, these externalities are not compensated. That's how pollution goes.

Somewhat unintuitively, the owners of the mineral rights have the superior right under law.
