Another earthquake shook Oklahoma today. It measured 3.1 on the Richter scale, and struck just after 7 a.m. near Stroud, 65 miles from Oklahoma City.
That's one of more than 500 this year, compared to California's 156. Scientists have linked Oklahoma's sharp increase in earthquakes in recent years to the underground injection of wastewater during oil and gas production.
Here & Now's Robin Young checks in with Joe Wertz, KGOU's StateImpact reporter, about Oklahoma's earthquake trends.
With reporting from the Associated Press.
