State and federal regulators say they are working on a new partnership in northeast Oklahoma after Saturday's record-tying magnitude 5.6 earthquake near Pawnee.

<p style="color:rgb(51,51,51);font-family:Georgia, serif;font-size:19px;">The U.S. Environmental Protection Agency will follow Oklahoma Corporation Commission recommendations and shut down 17 saltwater disposal wells in southwest Osage County, EPA said in an email to the Corporation Commission on Sunday. The email did not specify when the wells would close.

EARTHQUAKES IN OKLAHOMA

WHAT WE KNOW

<div style="font-family:inherit;font-style:inherit;">
<p style="font-family:inherit;font-style:inherit;">We know that Oklahoma experienced

<p style="font-family:inherit;font-style:inherit;">Magnitude 3+ Earthquakes

<p style="font-family:inherit;font-style:inherit;">2016: 623

<p style="font-family:inherit;font-style:inherit;">2015: 907

<p style="font-family:inherit;font-style:inherit;">2014: 585

<p style="font-family:inherit;font-style:inherit;">2013: 109

<p style="font-family:inherit;font-style:inherit;">While we understand that Oklahoma has historically experienced some level of seismicity, we know that the recent rise in earthquakes cannot be entirely attributed to natural causes. Seismologists have documented the relationship between wastewater disposal and triggered seismic activity. The Oklahoma Geological Survey has determined that the majority of recent earthquakes in central and north-central Oklahoma are very likely triggered by the injection of produced water in disposal wells.
