The U.S. Geological Survey reports an earthquake shook southern Kansas.
The earthquake happened at 3:46 a.m. Sunday and measured 4.0 on the Richter scale. Its epicenter was reported eight miles east-northeast of Anthony in Harper County.
It was at least the second earthquake in a week in the area. On Wednesday, a quake rated 3.4 on the Richter scale was recorded 14 miles east-northeast of Anthony.
Gov. Sam Brownback last month asked the director of the Kansas Geological Survey to lead a task force that’ll study whether human activity is causing an increase in minor earthquakes in Kansas.
