But what caused these earthquakes? Trey Davis with the Oklahoma Corporation Commission said they are looking at wells in the area, specifically wastewater injection wells, and for fracking operations.

"(The earthquake was) very near the 5.3 earthquake that occurred in that region back in 2011. We spent a couple hours last evening looking at activity in the area. This is not necessarily unusual for this area. Back in 2016 and 2017, we took action to shut in several wells, and we anticipate that's going to occur this time," Davis said.

He explained that sometimes, waste is injected into what's known as the Arbuckle, which runs across the entire state. However, Davis said that years ago they had begun pulling the wells out of the Arbuckle and to a shallower depth, limiting what could be injected.

As for the aftershocks, ranging from 2.9-mag. to 3.5-mag., Davis explained that they tend to happen either just north or just south of the epicenter. He said it's a very old fault line.

News 9's Deanne Stein talked to residents in Prague about what they felt Friday night.
