HUTCHINSON, Kan. (AP) A series of three earthquakes have rattled portions of south-central Kansas.
The Kansas Geological Survey says the strongest measured 3.8 and struck around 2:40 a.m. Monday in Chase County. Another trembler with a 3.6 magnitude was reported around 10 a.m. Monday in Marion County, and a third with a magnitude of 2.8 was reported around 10:30 a.m. Sunday in Reno County.The threshold for damage usually starts at 4.0.
Wastewater injection wells from oil and gas production are thought to play a role. A dozen quakes in Reno County have led the Kansas Corporation Commission to analyze recent injection well activity.
