Fracking triggers “potentially damaging” earthquakes, even in areas AWAY from injection sites
(Natural News) Earthquakes attributed to fracking operations are not limited to the areas around the injection site. A Tufts study has revealed that pumping fluids underground disturb natural networks of fault fractures that reach quite a ways off.
The fracking industry relies on subsurface fluid injection to recover oil and natural gas from deep underground. It also gets rid of wastewater this way.
The Tufts University study put together data from field experiments and ground fault models. It showed that subsurface fluid injection might trigger considerable and extensive seismic activity far from the diffusion zone.
Deep fluid injections have been shown to trigger more earthquakes. However, many believed that seismic activity only increased near the injected areas.
The Tufts researchers showed that fluid injections caused slippages in fault fractures that reached far beyond the diffusion zone. As a result, the technique might trigger potentially destructive earthquakes in distant areas.
Their findings might explain why some areas of the U.S. experienced more human-caused earthquakes than traditional hot spots for natural quakes. (Related: Is fracking just a cover for a corporate water grab? Control the water, control the people.)
