A 3.4 magnitude earthquake shook part of north-central Oklahoma Sunday morning. No damage was reported.
The U.S. Geological Survey says the quake was recorded at 5:40 a.m. Sunday about five miles south of Hennessey in Kingfisher County. Geologists reported that the quake was recorded at a depth of about one mile.
No damage or injuries were reported.
Thousands of earthquakes have been recorded in Oklahoma in recent years. Many of the quakes were thought to be from the underground injection of wastewater from oil and gas production.
