A 5.1 magnitude earthquake shook northwest Oklahoma and was felt in seven other states on Saturday, the U.S. Geological Survey said, the third-strongest temblor ever recorded in the state where the power and frequency of earthquakes has dramatically increased in recent years.
The earthquake centered about 17 miles north of Fairview in northwestern Oklahoma occurred at 11:07 a.m. and was reportedly felt across Arkansas, Iowa, Kansas, Missouri, Nebraska, New Mexico and Texas, the USGS said. A second quake measured at 3.9 magnitude struck ten minutes later, followed at 11:41 a.m. by a 2.5 magnitude quake and at 12:21 p.m. by a 3.5 magnitude temblor.
Oklahoma's stronger and more frequent earthquakes have been linked to the injection into the ground of the briny wastewater left over from oil and gas production. All four earthquakes Saturday were in the same lightly populated area near Fairview, a town of about 2,600 that's about 100 miles northwest of Oklahoma City. The area has had several quakes of magnitude 4 since the start of the year.
Fairview police and the Major County Sheriff's Office had no reports of injury or significant damage. Sheriff's dispatcher Cheryl Landes said there had been several calls from concerned residents, but no damage more than pictures knocked off shelves and walls.

They will not change until severe damage is done.
