The United States Geological Survey (USGS) has recorded 82 earthquakes in Kansas since June 12th.

The USGS has put several seismometers in Harper and Sumner Counties to try to locate where exactly the earthquakes are happening and how frequently.

The latest earthquake, a 3.4 magnitude quake near Caldwell, KS happened Tuesday night.

Geologists with the USGS and the Kansas Geological Survey are working to find out if the influx in earthquakes are connected to waste water injection wells in the area.

Waste water injection wells release large amounts of salt water and sometimes other chemicals deep produced during hydraulic fracturing into porous rock in order to get rid of it. Some geologists in other states have linked the process to multiple earthquakes, saying the water can cause a fault to slip.
