Oklahoma Earthquake FAQ

Why does Oklahoma have so many earthquakes recently?

Bar graph showing the number of M3+ Earthquakes in Oklahoma vs California from 1990 to 2019. California earthquake counts are shown as a blue bar and Oklahoma earthquake counts are shown as a red bar. (image: USGS)

Beginning in 2009, seismic activity in Oklahoma has been seeing a surge in seismicity. USGS published a statistics showing that during 2014-17, Oklahoma surpassed California in the number of quake of magnitude 3 and higher.
Most of the earthquakes in Oklahoma are caused, directly or indirectly, by oil and gas exploration. Although it does play a role, the process of fracking seems not to be the main culprit. According to USGS scientists, the vast majority of the recent quakes in Oklahoma were caused by the industrial practice known as "wastewater disposal".
During wastewater disposal fluid waste from oil and gas production is pumped deep underground at depths far below ground water or drinking water aquifers.
In Oklahoma over 90% of the wastewater that is injected comes as a byproduct of oil extraction process and not waste frack fluid. (Source: USGS)
