8 States Dealing With Huge Increases in Fracking Earthquakes
A new report, released Thursday from the U.S. Geological Survey (USGS), identified eight states in the eastern and central U.S. where fracking operations have led to dramatic increases in earthquakes, primarily from the injection of the wastewater byproduct of drilling operations into underground wells. This process can activate faults that in some cases were previously unknown.
“Earthquake activity has sharply increased since 2009 in the central and eastern United States. The increase has been linked to industrial operations that dispose of wastewater by injecting it into deep wells,” the report says bluntly, in a rebuke to the earthquake deniers in the oil and gas industry, such as fracking founder Harold Hamm, who pressured Oklahoma officials to stay silent about the connection.
While Oklahoma, Texas and Ohio have gotten much of the attention for increases in seismicity in areas where earthquakes were once rare, they aren’t the only states in danger of more and larger earthquakes. The USGS report also pointed to Alabama, Arkansas, Colorado, Kansas and New Mexico and identified 17 zones within the eight states in particular danger from an increased number of what it calls “induced” quakes.
The report, Incorporating Induced Seismicity in the 2014 United States National Seismic Hazard Model, analyzed these seismic activity increases and developed the models to project how hazardous earthquakes could be in these in these zones, taking into account their rates, locations, maximum magnitude and ground motions.
