Sumner County among most active counties for quakes

By Travis Mounts

Last year, Kansas experienced 431 earthquakes with a magnitude of 2.0 or greater, and many of them were in Sumner County.

That’s according to the Kansas Geological Survey’s review of 2019. Sumner County had the third-most quakes with 54. Rooks County led the state with 87, and Jewell County was next with 62.

Sumner County’s largest earthquake was a 4.4 on Jan. 15 that struck just east of South Haven. The county also saw a 3.6 near South Haven, and a 3.4 north of Caldwell. The rest of the county’s quakes were 2.9 or smaller.

Harper County saw 26 temblors in 2019, with three at 3.0 or higher. The largest was a 3.1 quake on Aug. 8 that was located west of Bluff City in the southern part of the county. A pair of 3.0 earthquakes happened early in 2019, one just a couple of miles west of Danville and the other in the northeast part of the county.

Sedgwick County recorded 12 earthquakes in 2019. The largest was a 3.1 on Nov. 30 that struck about eight miles south of Cheney, eight miles west of Viola and about 5 miles northeast of Norwich.

The state’s largest earthquake in 2019 was a 4.8 in Rooks County.

The KGS report does not reflect any northern Oklahoma earthquakes that may have been felt in south-central Kansas.
