PAWNEE, Okla.(AP) -- Seismologists upgraded Saturday morning's earthquake, making it the largest in state history.
The U.S. Geological Survey estimates the magnitude of the quake at 5.8. That's slightly up from the first estimated 5.6 magnitude. The quake was centered near Pawnee. That's 50 miles northwest of Tulsa.
Many in the Ozarks say they woke up to shaking from the earthquake.
The Pawnee County emergency management director says one minor injury was reported and no buildings have collapsed.
Several aftershocks have followed in that same area since. The number of magnitude 3.0 or greater earthquakes has skyrocketed in Oklahoma, from a few dozen in 2012 to more than 900 last year.
