“I don’t remember the earthquake in this area,” Hamilton told NBC News. He said earthquakes are rare in his area of ​​western Oklahoma.

Central part of the state Recently it was an area of ​​intense seismic activity, Mainly thanks for oil and gas drilling. Mining techniques involving pressurized fluids, known as hydraulic fracturing, have been blamed for the earthquake, but the USGS says wastewater from mining is the main suspect.

“Most of the Oklahoma earthquakes are caused by an industrial practice known as” wastewater treatment. ” ” USGS writes..

“Wastewater treatment is a separate process in which fluid waste from oil and gas production is injected deep underground, well below the groundwater or drinking water aquifer. In Oklahoma, more than 90% of the injected wastewater is It is a by-product of the oil extraction process, so don’t waste your drinking water. “

From 2014 to 2017, the state had more than three magnitude temperers than the famous earthquake-prone California. USGS reported..

However, due to the caution against earthquakes caused by wastewater treatment, the wells were closed and seismic activity decreased.

Hamilton said he was aware that there were no new hydraulic fracturing activities in the area.

Correction (May 25, 2021 6:40 pm ET): Earlier versions of this article misunderstood which state felt the quake. It was felt in Oklahoma, Texas, Kansas, not in Oklahoma, Texas, Nebraska.
