Earthquakes, winter stoms invade Midwest

Published 3:30 pm Monday, November 30, 2015

ENID, Okla. — Mother nature has been in full force over the weekend in Oklahoma. After being hit with an ice storm that left more than 100,000 without power, the state was struck by an earthquake early Monday morning.

According to the United States Geological Survey, the earthquake in northwest Oklahoma was a 4.7 on the Richter scale that woke several in northwest Oklahoma just before 4 a.m.

It was the second quake of that magnitude to hit the area in less than two weeks. The first came Nov. 19 and prompted state regulators to shut down some oil and gas wastewater disposal wells in the area and reduce the volume at others.

Monday’s quake was centered just north of Nash, Oklahoma, 24 miles of northwest Enid, Oklahoma. The earthquake was 3.1 miles deep and occurred at 3:49 a.m., according to United States Geological Survey’s website.

Social media sites and apps lit up as the quake was felt in Enid and across Oklahoma and into Kansas. According to Facebook posts, the quake was felt as far away as Jenks, Oklahoma nearly two hours away.

Two more earthquakes came within hours of the initial shock. The first — with a magnitude of 3.0 — centered just outside the Oklahoma City took place at 5:50 a.m. The third quake struck at 7 a.m. southwest of Covington, Oklahoma, 22 miles east-southeast of Enid, Oklahoma. The 3.1 magnitude quake was 1.7 miles deep.

During this record-breaking year for earthquakes in Oklahoma, operations at the Oklahoma Geological Survey (OGS) is still dealing with the sudden departure of two seismologists. But the director of OGS says their office has not been compromised.

“Some aspects of the longer term interpretation of the earthquake data are slowed somewhat, but work on the complex mix of geology, hydrology and seismology that must be integrated to address Oklahoma earthquakes continues,” OGS Director Jeremy Boak said.

The lead seismologist has not yet been replaced, but Boak said he is hopeful the position will be filled in early 2016. A research seismologist position, vacated recently, may be filled internally soon.

“Our lead analyst is a seismologist, and we have one other seismologist who has been filling in for (the former research seismologist). We also have a seismology technician who is ensuring the network is up and running. In addition, we have the participation of a seismologist from the ConocoPhillips School of Geology and Geophysics, as well as a hydrogeologist and several geologists, geophysicists and petroleum engineers working on aspects of the problem,” Boak said.

Boak previously predicted the state would surpass the 2014 record for earthquakes, unless the situation changed “surprisingly” in the last few months of the year.

According to OGS records, there have been more than 800 magnitude 3.0 or greater earthquakes recorded in Oklahoma this year. The figure includes just over 30 magnitude 4.0 or greater quakes. 

In 2014, there were 585 magnitude 3.0 or greater earthquakes recorded in the state, with 14 of those measuring magnitude 4.0 or greater.

The quakes come as utility crews are attempting to restore power to thousands in the area after days of rain and freezing rain.

The winter storm has accounted for 14 deaths in the Kanas and Texas. Oklahoma Gov. Mary Fallin issued a disaster declaration for all 77 Oklahoma counties on Sunday, which will allow state agencies to make emergency purchases related to disaster relief and preparedness. The declaration also allows oversized vehicles, such as those transporting utility poles, to drive into affected areas.

As of Monday Monday morning, more than 53,000 homes and businesses were still without electricity due to the ice storm in Oklahoma. An additional 10,000 are without power in Kansas, according to the Associated Press.

According to Dan Pydynowski, senior meteorologist with Accuweather, more severe weather is coming.

“There is going to be more snow and wintry weather on the way,” Pydynowski told USA Today. “But it’s going to be focused a little farther north. Areas like Oklahoma, North Texas and eastern Kansas won’t be that bad.”
