A moderate earthquake may have added an extra jolt to the morning for some residents in Oklahoma and Kansas. The 4.2 magnitude quake struck just before 8 a.m. CST, about 4 miles west of Manchester, Oklahoma, around 40 miles north of Enid. The preliminary magnitude of the quake came in around 4.5, before being upgraded to 4.8. Further review by the USGS and Oklahoma Geological Survey downgraded the quake to a magnitude of 4.2.

Light shaking, as indicated by the USGS map above, was felt in other larger metropolitan areas like Oklahoma City and Wichita. This may have to do with the relatively shallow depth of the quake, about 4.3 miles, or 7 km, below the surface.
