Oklahoma governor declares emergency after quake

Oklahoma Gov. Mary Fallin has declared a state of emergency in Pawnee County after a magnitude 5.6 earthquake struck northwest of Pawnee.  The earthquake struck at 7:02 a.m. Saturday and was felt throughout the Midwestern United States, although no severe damage or serious injuries were reported. The quake ties a 2011 earthquake for the strongest earthquake in recorded state history. The Oklahoma Corporation Commission is requiring the shutdown of 37 wastewater disposal wells in the area around the epicenter of a magnitude 5.6 earthquake.  The mandate from the commission's Oil and Gas Division comes after the Saturday morning earthquake near Pawnee and includes 514 square miles under commission jurisdiction. Commission spokesman Matt Skinner says another 211 square miles in Osage County is under the jurisdiction of the Environmental Protection Agency.  He says the commission is working with the EPA, which will decide what action to take there.
