EARTHQUAKES AND HYDRAULIC FRACTURING EARTHWORKS FACT SHEET
A two page fact sheet prepared by Earthworks, January, 2014.
Earthquake Hazard Associated With Deep Well Injection
The US has known underground injections causes earthquakes for more than twenty years. "Under certain circumstances, the increased pore pressure
resulting from fluid injection, whether for waste disposal,secondary recovery, geothermal energy, or solution mining,can trigger earthquakes. This report discusses known cases of injection-induced seismicity and how and why earthquakes may be triggered..." A Report to the U.S. Environmental Protection Agency by the US Geological Survey, 1990.
On Shaky Ground: Fracking, Acidizing, and Increased Earthquake Risk in California
This report analyzes the earthquake risks associated with an increase in wastewater injection that would result from an expansion of fracking and other unconventional oil production in California’s Monterey Shale, by Jhon Arbelaez, Shaye Wolf, Ph.D., and Andrew Grinberg for Earthworks, Center for Biological Diversity and Clean Water Action, March, 2014.
Examination of Possibly Induced Seismicity from Hydraulic Fracturing in the Eola Field, Garvin County, Oklahoma
Induced Seismicity Potential in Energy Technologies
"Since the 1920s we have recognized that pumping fluids into or out of the Earth has the potential to cause seismic events that can be felt." By the National Research Council of the National Academies,June 15, 2012.
Enhanced Remote Earthquake Triggering at Fluid-Injection Sites in the Midwestern United States (Abstract)
A recent dramatic increase in seismicity in the midwestern United States may be related to increases in deep wastewater injection. By: Nicholas J. van der Elst, Heather M. Savage, Katie M. Keranen, Geoffrey A. Abers, July 12, 2013 Science Magazine.
