A southern Kansas county was shaking after a pair of earthquakes were reported within hours of each other but apparently didn’t cause any damage.

The U.S. Geological Survey reports the first earthquake to hit Harper County was at 7:30 a.m. Tuesday and was measured 3.3 on the Richter scale. The second temblor that hit the county was at 9:55 a.m. and measured 4.1 on the Richter scale.

The second earthquake happened about two miles east of the first quake. Wichita media outlets say calls about the second quake came from as far north as Manhattan, Kansas.
