Wastewater disposal linked to earthquakes The number of earthquakes is increasing in regions with active unconventional oil and gas wells, where water pumped at high pressure breaks open rock containing natural gas, leaving behind wastewater in need of disposing. Keranen et al. show that the steep rise in earthquakes in Oklahoma, USA, is likely caused by fluid migration from wastewater disposal wells. Twenty percent of the earthquakes in the central United States could be attributed to just… 
Hydraulic Fracturing and Seismicity in the Western Canada Sedimentary Basin
The development of most unconventional oil and gas resources relies upon subsurface injection of very large volumes of fluids, which can induce earthquakes by activating slip on a nearby fault.
Widespread deep seismicity in the Delaware Basin, Texas, is mainly driven by shallow wastewater injection
It is shown that the widespread deep seismicity is mainly driven by shallow wastewater injection through the transmission of poroelastic stresses assuming that unfractured shales are hydraulic barriers over decadal time scales, with impacts on seismicity that are preconditioned by regional tectonics.
Oklahoma’s recent earthquakes and saltwater disposal
In three study areas that encompass the vast majority of the recent seismicity, it is shown that the increases in seismicity follow 5- to 10-fold increases in the rates of saltwater disposal.
High density oilfield wastewater disposal causes deeper, stronger, and more persistent earthquakes
It is shown that high-density oilfield wastewater may sink deeper in the Earth’s crust than previously considered possible, thus increasing fluid pressure and inducing earthquakes for years after injection rates decline.
High-rate injection is associated with the increase in U.S. mid-continent seismicity
It is found that the entire increase in earthquake rate is associated with fluid injection wells, and high-rate injection wells are much more likely to be associated with earthquakes than lower-rate wells.
Myths and Facts on Wastewater Injection, Hydraulic Fracturing, Enhanced Oil Recovery, and Induced Seismicity
The central United States has undergone a dramatic increase in seismicity over the past 6 years (Fig. 1), rising from an average of 24 M≥3 earthquakes per year in the years 1973–2008 to an average of
A Century of Induced Earthquakes in Oklahoma
Seismicity rates have increased sharply since 2009 in the central and eastern United States, with especially high rates of activity in the state of Oklahoma. Growing evidence indicates that many of
Oklahoma experiences largest earthquake during ongoing regional wastewater injection hazard mitigation efforts
The 3 September 2016, Mw 5.8 Pawnee earthquake was the largest recorded earthquake in the state of Oklahoma. Seismic and geodetic observations of the Pawnee sequence, including precise hypocenter
The 2016 Mw5.1 Fairview, Oklahoma earthquakes: Evidence for long-range poroelastic triggering at >40 km from fluid disposal wells
Abstract Wastewater disposal in the central U.S. is likely responsible for an unprecedented surge in earthquake activity. Much of this activity is thought to be driven by induced pore pressure
Characterizing and Responding to Seismic Risk Associated with Earthquakes Potentially Triggered by Fluid Disposal and Hydraulic Fracturing
For nearly a century, earthquakes apparently triggered by fluid injection have been observed in many parts of the world (National Research Council [NRC], 2012). Although injection‐related seismicity


Enhanced Remote Earthquake Triggering at Fluid-Injection Sites in the Midwestern United States
It is demonstrated that in the midwestern United States, some areas with increased human-induced seismicity are also more prone to further earthquakes triggered by the seismic waves from large, remote earthquakes.
Disposal of Hydrofracking Waste Fluid by Injection into Subsurface Aquifers Triggers Earthquake Swarm in Central Arkansas with Potential for Damaging Earthquake
Only a handful of the thousands of waste disposal wells across the United States have been linked to induced or triggered earthquakes. Still, two well-documented cases—Rocky Mountain Arsenal,
Potentially induced earthquakes in Oklahoma, USA: Links between wastewater injection and the 2011 Mw 5.7 earthquake sequence
Significant earthquakes are increasingly occurring within the continental interior of the United States, including five of moment magnitude (Mw) ≥ 5.0 in 2011 alone. Concurrently, the volume of fluid
Injection-Induced Earthquakes
The current understanding of the causes and mechanics of earthquakes caused by human activity, including injection of wastewater into deep formations and emerging technologies related to oil and gas recovery, is reviewed.
Maximum magnitude earthquakes induced by fluid injection
Analysis of numerous case histories of earthquake sequences induced by fluid injection at depth reveals that the maximum magnitude appears to be limited according to the total volume of fluid

We investigate the ongoing seismicity in the Raton Basin and find that the deep injection of wastewater from the coal-bed methane field is responsible for inducing the majority of the seismicity
Induced seismicity associated with fluid injection into a deep well in Youngstown, Ohio

Between November 2009 and September 2011, temporary seismographs deployed under the EarthScope USArray program were situated on a 70-km grid covering the Barnett Shale in Texas, recording data and located 67 earthquakes, more than eight times as many as reported by the National Earthquake Information Center.
