In 2014, Oklahoma had more than three times as many earthquakes as California, and this year, the state is on track for even more. A lot of them are small, but some towns are seeing a quake almost every day, and seismologists warn that large and damaging earthquakes are becoming more likely. The government in the Sooner State has only recently acknowledged the scope of the oil and gas industry’s role in the problem.

Reveal’s Michael Corey and Joe Wertz of StateImpact Oklahoma hop in a car and drive toward the epicenter of two earthquakes that had just struck near the town of Guthrie, Oklahoma, to see the after-effects for themselves and talk to the people who live in the area. Are residents troubled by or numb to the earthquakes?

In this story, the reporters travel throughout the state speaking to experts, helping us gain a better picture of Oklahoma’s man-made earthquakes.
