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.
Meteorologists at the National Weather Service in Tulsa, about 125 miles away from the epicenter, felt the earthquake.
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.
