Last week a series of studies was published in Science, which looked at the connections between energy production and earthquakes. Specifically, they examined the connection between injecting fluid underground and seismic activity. Certainly there has been a number of well-publicized incidents in the past couple of years where hydraulic fracturing operations have been linked to earthquakes; it's pretty much conventional green wisdom at this point.
Given the controversy surrounding fracking, it's not surprising that most reporting on the studies jumped on that connection. Mother Jones seemed to be first out the gate. At least I saw "Confirmed: Fracking Triggers Quakes and Seismic Chaos" before anything else.
It's a good summary of two of the three studies lumped together by the publishers around this topic—the gist of which is that in the case of fracking, it's the disposal wells rather than the drilling itself that has the biggest connection with earthquakes, and which can have truly far reaching consequences. It's important research, and another strike against fracking.
