September 3, 2016 Oklahoma earthquakes

A magnitude 5.6 earthquake rattled oil country in Oklahoma on September 3, 2016 at 7:02 a.m. The quake’s epicenter was eight miles northwest of Pawnee, OK. The USGS maps of the quake are detailed.

The Pawnee Nation declared a state of emergency after ordering evacuations of damaged buildings in the area.

Historically, the incidence of earthquakes in Oklahoma is low, and there is concern in the state that these earthquakes are of man-made origin.

Previous quakes in the area have been linked to the use of injection wells to dispose of drilling waste. A March 2016 New York Times story detailed the efforts of the state government to limit the use of these wells.
