The six largest earthquakes locations are very well constrained and on relocation we expect the magnitude 2.1 earthquake to centered with the cluster. The cluster of six earthquakes is 7 miles west of Union City Oklahoma in Canadian County near the border with both Grady and Caddo Counties. The cluster is about 11 miles SSW of El Reno.
