Earthquakes Rattle Oklahoma Residents
A record-breaking 5.1-magnitude earthquake struck Oklahoma early Saturday morning.
The U.S. Geological Survey (USGS) reported the epicenter of the earthquake was 17 miles northwest of Fairview, Oklahoma.
“We have no reports of damage as of yet, but we did get a good rock n’ roll,” Cheryl Landis with the Major County Sheriff’s Department tells CNN.
The earthquake occurred at 12:07 a.m. (1:07 a.m. Friday ET) at a depth of 1 kilometer, the USGS said.
A 3.9 magnitude earthquake around11:17 a.m., a 2.5 around 11:40 a.m. and a 3.5 around 12:21 p.m. were also recorded in the same area, according to KFOR.
This is the strongest quake to rattle the state since 2011, the Survey says.
Though Oklahoma has a history of earthquakes, the USGS suggests that there has been a significant increase in the rate of quakes since 2009.
The USGS says waste water injected into deep geologic formations is a likely contributing factor to the seismic activity increase. This method of retrieving oil and natural gas is known as hydraulic fracturing, or fracking.
