Sandstone bricks from the side of the historic Pawnee County Bank litter the sidewalk after an early morning earthquake in Pawnee, Oka., on Saturday, Sept. 3, 2016. The United States Geological Survey said a 5.6 magnitude earthquake happened Saturday morning in north-central Oklahoma, on the fringe of an area where regulators had stepped in to limit wastewater disposal. That temblor matches a November 2011 quake in the same region.
