Global Warming and Energy

Blaming fracking for big earthquakes.

"Natural-gas extraction, geothermal-energy production and other activities that inject fluid underground have caused numerous earthquakes in the United States, scientists have reported in a trio of papers in Science (abstracts here, here and here). Most of these quakes have been small, but some have exceeded magnitude 5.0. They include a magnitude-5.6 event that hit Oklahoma on 6 November 2011, damaging 14 homes and injuring two people."

Lubricating faults with water might allow plates to slip at lower energy than higher energy, reducing the damage from earthquakes, but I don't see how it can create earthquakes.
