CALDWELL, Kan. (AP) — Another small earthquake has shaken south-central Kansas.
The Kansas Geological Survey says the latest quake struck Saturday night near the small Sumner County town of Caldwell. It had a preliminary magnitude of 2.5. At least one earthquake a day has rattled the area since Tuesday, with magnitudes ranging from 2.2 to 3.1.
More than 200 earthquakes have been recorded in Kansas since Jan. 1, 2013. Only five were detected in the previous 10 years. Many have been centered in Sumner and Harper Counties. The Kansas Geological Survey said last month that the increase in the two counties was linked to saltwater injection after oil and natural gas drilling.
