Sandstone bricks from the side of the historic Pawnee County Bank litter the sidewalk after an early morning earthquake in Pawnee, Oka., on Saturday. 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.
