WICHITA, Kan. (AP) — Two earthquakes have hit south-central Kansas, and one could be felt almost 100 miles away.

The U.S. Geological Survey says an earthquake measuring 3.3 on the Richter Scale hit southwest of Pratt near Sun City in Barber County on Saturday morning. A second earthquake measuring 4.0 hit in nearly the same area about three hours later.

The second earthquake could be felt in Wichita. The Wichita Eagle reports both earthquakes measured about three miles deep.

More than 200 earthquakes have been recorded in Kansas since 2013 in an unprecedented spike in seismic activity. In April, the U.S. Geological Survey released a report that said man-made quakes tied to oil industry operations have been on the rise.
