What We Know

While we know 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.

Oklahoma’s response to the recent rise in earthquakes is constantly evolving based on the growing body of knowledge dedicated to exploring the issue.
