Facebook post from U.S. National Weather Service, Springfield, MO. Seismogram from a station near Bolivar, MO showing an earthquake (9/3/2016) which was felt across at least 7 states in the Central U.S. (This earthquake was not a result of the New Madrid or Bolivar-Mansfield faults, the epicenter was in Oklahoma)

"The Chesapeake and Bolivar-Mansfield Fault Systems are inactive features that lie on the Border between Kansas and Missouri. ... ' The Bolivar-Mansfield Fault System (see No. 5 in Missouri on Figure 2.5L-5) is a broad zone of discontinuous; generally parallel faulting that extends northwest from Douglas through St.Clair and Bates counties, Missouri into Kansas, approximately 150 miles (240 km) west-southwest of the Site. Many of the individual faults in this system have been named separately. This zone may extend southeastward into Arkansas (McCracken, 1971, in AmerenUE, 2004) and has been extended northwestward through Bates County by Gentile (1965, 1976). The Eldorado Springs North fault has been extended from Bates County into Kansas (McCracken, 1971, in AmerenUE, 2004) and is shown as an unnamed fault on the top of the Precambrian in Linn County, Kansas by Cole (1976). It had previously been interpreted as a valley on the basement surface (Cole, 1962). The system appears to border the southwest flank of the Ozark Uplift. Faulting is mostly high angle normal, with throws of up to 300 ft (91m) McCracken, 1971, in AmerenUE, 2004). The faulting involves beds ranging in age from early Pennsylvanian (Cherokee Group) to early Ordovician (Roubidoux Formation)' "-- FSAR: Section 2.5.1
