Fracking Earthquakes in Arkansas

They continue to say that no damage was caused by the drilling induced earthquakes in Texas and that is not true. The Boy Scout Museum sustained $100,000 worth of damage. Who knows what kind of damage foundations, pipelines or well casings might have incurred that won’t show up immediately.

Arkansas is having fracking quakes.

Though the theory that the “fracking” operation triggers small earthquakes “seems reasonable,” Langston said he didn’t “think well injection would cause an overly large earthquake,” because the fractures the process creates run only as far as 100 meters, which he said isn’t enough to unsettle the structures to the point of producing damaging earthquakes.

First, they don’t know how far fractures travel and they have admitted that. Secondly, no one can say that small earthquakes don’t or won’t cause damage. Seismic testing causes damage so it’s not unreasonable to think that an earthquake 4.0 or below could cause damage to our homes and to pipelines and well casings.

We need to continue to ask this question: Who pays?

This is from Stanford University: GROUND RUPTURE IN THE BALDWIN HILLS

Drilling and water “re-injection” caused a dam to break.

In December of 1963 the newly constructed baldwin Hills Reservoir failed with five deaths and a great deal of property damage. The event was captured on TV. (See recent “Wrath of God” episode on the Discovery channel for live coverage of the failure.)
…
The role of central graben subsidence, accelerated by oil extraction, supplemented by reinjection of waste brine into the ground, on fault movement beneath the reservoir is indicated in the animated graphic following. Injection pressures exceeded hydrofracture pressures and the recorded timing of the fault offset (which was dutifully recorded by the reservoir owner) indicate the injection as being the decisive factor.
