Oklahoma was hit by one of the strongest earthquakes in the state’s history over the weekend.

The United States Geological Survey (USGS) said the magnitude 5.1 earthquake struck just after 11 a.m. on Saturday, and it was centered about 21 miles northwest of Fairview. According to the Oklahoma Geological Survey (OGS), it was the third-strongest quake ever recorded in the state.

Residents reported feeling strong-to-very-strong shaking near the quake’s center, according to user-submitted data on the USGS website. The agency says such shaking is capable of causing light or moderate damage, but there weren’t any such reports from Saturday’s earthquake.

Cities hundreds of miles away from Fairview experienced lighter shaking.

They included Oklahoma City (100 miles southeast), Fayetteville, Arkansas, (256 miles east), Dallas-Fort Worth (275 miles south) and Kansas City (300 miles northeast), the USGS said.

Five smaller earthquakes followed within 65 minutes of the initial quake, according to the USGS. Those other quakes ranged in magnitude from 2.5 to 3.9.

Oklahoma has seen a significant rise in seismic activity since 2009, and officials have linked the rise to wastewater from oil and gas production. Regulators have taken steps to limit its disposal.

However, the USGS says more than 300 earthquakes of magnitude 2.5 or greater have occurred in Oklahoma in the first 46 days of 2016. That includes eight earthquakes above magnitude 4.0.

Oklahoma only saw 21 magnitude-4.0-or-greater quakes in a 64-month stretch from January 2009 to May 2014, the USGS said in a news release at the time. That includes a magnitude 5.6 earthquake that occurred in November 2011 near Prague, the strongest in the state’s history.

Oklahoma’s second-strongest earthquake was a magnitude 5.5 quake that occurred in April 1952 near El Reno, according to the OGS. The state hasn’t witnessed any other magnitude 5.0 quakes.

However, the USGS and OGS have both warned the recent rise in Oklahoma’s earthquake activity increases the risk that the state could be hit by an even bigger quake in the future.

Last month, Fairview was hit by 20 earthquakes in a span of about nine hours, including two just 30 seconds apart. Those nearly back-to-back earthquakes were initially reported to be
