More Earthquakes Sunday Morning

Associated Press - February 14, 2016 7:56 am

earthquake damage

Sunday started much the same way Saturday ended, with the ground shaking in parts of the Midwest. According to the U.S. Geological Survey, three earthquakes were recorded along the Kansas / Oklahoma border before 7:00 in the morning. Early morning quakes included:

  • 2.8 at 4:41 AM
  • 3.9 at 5:25 AM
  • 2.9 at 6:35 AM

The three quakes came just a day after a 5.1 magnitude earthquake shook northwest Oklahoma and was felt in seven other states. It was 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. At least 10 smaller quakes ranging in magnitude from 2.5 to 3.9 were recorded in the same area by late Saturday afternoon, according to the USGS. A magnitude 3.1 quake occurred near Crescent, about 75 miles east of Fairview, the USGS said.

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. The 10 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 4.0 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.The strongest earthquake on record in Oklahoma is a magnitude 5.6 temblor, which has also been linked to wastewater injection. It was centered in Prague, about 55 miles east of Oklahoma City, in November 2011 and damaged 200 buildings and shook a college football stadium in Stillwater, about 65 miles away. The second-strongest was a 5.5 magnitude earthquake in April 1952 that was centered in El Reno, on the western edge of Oklahoma City.

The hundreds of recent quakes have been mostly small to medium sized, and have caused limited damage. But a quake did knock out power in parts of an Oklahoma City suburb several weeks ago, and last month about 200 unhappy residents packed a forum at the state capitol convened by critics of the state’s response.

Regulators have recommended reducing the volume or shutting down some of the disposal wells. Gov. Mary Fallin last month approved the use of nearly $1.4 million in state emergency funds for state agencies working to reduce the number of earthquakes linked to the wastewater disposal.

Oil and gas operators in Oklahoma, where the industry is a major economic and political force, have resisted cutting back on their injections of wastewater.

The Oklahoma Corporation Commission, which oversees the oil and gas industries in the state, said Saturday that it completed the major work last week on a regional plan to address earthquakes in western Oklahoma.

“The plan will involve a large-scale regional reduction in oil and gas wastewater disposal for an approximately 5,000 square mile area in western Oklahoma,” spokesman Matt Skinner said. He said the complete plan will be released Tuesday.
