I could have told them this (see diagram):
Some experts think that pumping water into the ground as part of the extraction process of natural gas could cause local seismic events. But the area hasn’t been studied enough, they say, to know for sure.
One thing Ausbrooks said should be emphasized is that there is no evidence that the fracturing or “fracking” of natural gas bearing shale has anything to do with the shaking. Fracking is when high-pressure fluid is used to fracture the rock, and draw out more gas. “There is no data to say it’s from the hydro fracking process,” he said.
Northrup says that the technique is akin to exploding a bomb underneath the ground and is an all around bad idea.
