A shallow 5.1 magnitude earthquake occurred on 21 January in central Oklahoma, near Prague, and was felt as far as Kansas and Texas. The earthquake was followed by at least six aftershocks ranging from 2–3.5 magnitude. No damage or injuries have been reported. The strongest earthquake on record in Oklahoma was a 5.8 magnitude earthquake near Pawnee in 2016. Officials are investigating the potential link between the earthquake and recent oil production in the area.
