An early morning quake centralized in the northern part of Oklahoma shook residents from Texas to Missouri on Saturday morning.
An increase in magnitude 3.0 or greater earthquakes in Oklahoma has been linked to underground disposal of wastewater from oil and natural gas production. State regulators have asked producers to reduce wastewater disposal volumes in earthquake-prone regions of the state. Some parts of Oklahoma now match northern California for the nation’s most shake prone, and one Oklahoma region has a 1 in 8 chance of a damaging quake in 2016, with other parts closer to 1 in 20.
It appears that the cause of this earthquake is fracking. Is fracking really worth it?
