The largest earthquake induced by fluid injection that has been documented in the scientific literature was a magnitude 5.8 earthquake on September 23, 2016 in central Oklahoma. Four magnitude 5+ earthquakes have occurred in Oklahoma, three of which occurred in 2016.
Jul 21, 2021 · In southcentral Kansas, the Wellington earthquake catalog is primarily composed of local, low‐magnitude events. Approximately 22% of recorded earthquakes over a 2.5 yr period exhibit a seismic phase arriving between the direct P phase and direct S phase with particle motion similar to the P wave.

Feb 1, 2018 · WASHINGTON (AP) — A new study finds that a major trigger of man-made earthquakes rattling Oklahoma is how deep — not just how much — fracking wastewater is injected into the ground. Scientists analyzed more than 10,000 wastewater injection wells where 96 billion gallons of fluid — leftover from hydraulic fracturing — are pumped yearly.

Sep 10, 2015 · Here's a USGS map that shows all of the 1,800-plus earthquakes, 2.5 magnitude or higher, that have hit Oklahoma since the beginning of this year. Compare this to the map of Oklahoma's fault lines.
To approximate data windows dominated by subvertical incidence P-wave energy, we use a catalog of 17,615 earthquake events ( Figure 2) of magnitude greater than 2.0 with epicenters in Oklahoma.
Sep 26, 2018 · Seismic activity in north-central Oklahoma and southernmost Kansas peaked in 2015, when 943 widely felt M ≥ 3 (31 M ≥ 4) earthquakes occurred 11 in response to the dramatic increase in produced...

Nov 3, 2015 · 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 these events are induced, primarily by injection of wastewater in deep disposal wells.
