WICHITA, Kan. (KSNW) – Wichitans were shaken by an earthquake Tuesday. It happened just before 11 a.m. It is the fourth in the area in weeks.

The United States Geological Survey(USGS) reports the quake measured a 3.0 magnitude in northeast Wichita. The Kansas Geological Survey (KGS) is reporting the quake measured a magnitude 3.3. The earthquake was centered around 21st and Rock Road.

KSN News viewers in Wichita reported their apartments and homes shaking.  No serious damages or injuries were initially reported after Tuesday’s quake. 

Last month in Wichita, other earthquakes were reported on Nov. 27 and Nov. 30.

“I don’t think the earthquakes necessarily get any larger than what we felt. So, it’s not leading to something massive I don’t think,” said William Parcell, Wichita State University Department of Geology chair. “It’s certainly disturbing when it happens and feels very, makes you feel very insecure.”

Parcell said they haven’t been able to run experiments yet on the earthquakes, and they don’t know exactly why they occurring. He has a theory.

“But from other earthquakes that we’ve seen occurring in the area in the past few years, it may have something to do with wastewater injection wells in south-central Kansas in northern Oklahoma,” said Parcell. “There aren’t any wastewater injection wells in east Wichita that I’m aware of, but the wastewater that is injected can flow away from the well that it’s injected into and influenced the pressures on faults in the, in the near vicinity.”

The city of Wichita said they are initiating targeted inspections due to the size of the earthquake. The city said a couple of inspections have been completed, and so far, there are no reports of damage at City Hall or any reports of damage at outlying facilities.

Back on Sept. 3, 2016, a 5.6 magnitude earthquake rattled a swath of the Great Plains, from Kansas City, Missouri, to central Oklahoma. It was centered in Oklahoma.
