Potential link between wastewater injection and M5.7 earthquake in Oklahoma

Key findings:
Injection-induced earthquakes could be larger and they could occur on much longer timescales than previously thought.
Induced earthquakes could be larger than previously thought, since this type of deep waste fluid injection has the potential to unlock tectonic stresses built up over decades.A 5.7 magnitude frackquake near Prague, OK, in 2011 damaged 14 homes and other structures in an area historically seismically inactive.
