HARPER, Kan. (AP) — Southern Kansas experienced nearly two dozen earthquakes in the past week, including 10 separate quakes centered in a quarter-section of land five miles southeast of Harper.

U.S. Geological Survey records indicate the cluster of earthquakes occurred between 8:23 p.m. Friday and 5:04 p.m. Sunday in Harper County, with several occurring just 10 to 20 minutes apart.

The Hutchinson News reports the largest of quakes in that cluster had a magnitude of 2.5, with the others between 1.8 and 2.27. Two other quakes that happened within a mile of the cluster both had a magnitude of 3.1.

The cluster was among 18 earthquakes recorded in Harper County in the past week.

Sumner County recorded four earthquakes, including three in a tight cluster 5 miles east of Caldwell.
