A small earthquake has been reported in southern Kansas. 

The U.S. Geological Survey said a magnitude 4.4 earthquake, which was later upgraded to a 4.5 magnitude, struck near Hutchinson shortly after 1 p.m. Sunday. No damage was immediately reported. 

The Hutchinson News reports that the earthquake happened near where several others have happened recently in Reno County. Kansas began seeing a spike in earthquakes in 2014 that were blamed on wastewater injection wells from oil and gas production. The number of quakes began tapering off after oil prices dropped and regulations were enacted.
