A swarm of earthquakes has shaken parts of Alfalfa County in northern Oklahoma. The U.S. Geological Survey says four earthquakes have been recorded around Cherokee and Helena since late Wednesday, including a magnitude 4.3 quake about five miles east-northeast of Cherokee at 9:08 a.m. Thursday. Alfalfa County Sheriff’s Department office manager Amanda Kutz says the earthquake damaged parts of the courthouse in Cherokee. Kutz says plaster is peeling off interior walls and there is damage to the ceiling on the building’s third floor.
