ENID, Okla. — Two magnitude 4.2 earthquakes were recorded near Enid Sunday afternoon and evening, according to the U.S. Geological Survey.
The first quake, at 5:17 p.m., was centered 10 miles east-northeast of Enid, according to the U.S. Geological Survey. It was 1 mile deep.
A second magnitude 4.2 earthquake was recorded at 9:40 p.m. Sunday in the same area with a depth of 3 miles, according to the USGS.
Two more smaller quakes occurred Monday, according to USGS. The first was a magnitude 2.7 that struck at 12:35 a.m. about 9 miles northeast of Enid and 3.8 miles north-northwest of Breckinridge. It was 2.4 miles deep. The second was a magnitude 2.6 that struck at 6:16 a.m. about about 8.7 miles northeast of Enid and 2.9 miles north-northwest of Breckinridge. it was 3 miles deep
At least one home in Breckinridge had major brick separation from doors and windows following the first quake, Enid and Garfield County Emergency Management Director Mike Honigsberg said.
There were also structural issues with sheetrock cracking above doors and windows, and some stairstep cracking in some areas of brick, he said.
The home appeared to be safe enough to stay in, but a structural engineer will need to evaluate it, Honigsberg said.
"I haven't had to deal with earthquake damage like this before," he said, after he had been at the scene. "This will be more of an insurance issue than anything else."
Jonah and Brandi Davidson, who just moved into the home two weeks ago, do have earthquake insurance.
Brandi Davidson was at home, in the kitchen, when the first earthquake suddenly struck.
"It sounded like an explosion," she said.
Everything shook, and items fell off walls, Davidson said.
"I knew it was at our back door. I knew it was close. It rattled our feet on the ground," she said.
It took some time to discover the damage to the home.
"I think we were in shock," Davidson said.
The USGS shows the updated epicenter of the first earthquake just north of Breckinridge, just northwest of the intersection of Breckinridge Road and Hunter Road.
Honigsberg advised that anyone living within at least 5 miles of the epicenter should check for damage and contact their insurance agent if there is damage.
“I need folks who live in Breckinridge and those that live within 5 miles of the epicenter to check around their homes for any brick and other structural damage (Monday) morning. If you have this kind of damage, contact your insurance agent immediately.
“On the inside of your home, check all corners above your windows and doors for cracks. Again, contact your insurance agent. Hopefully, you have earthquake insurance.”
He asked that any damage also be reported to him at firstname.lastname@example.org.
First quake reaction
People reported feeling the first earthquake in Stillwater, Mooreland and in Wichita, Kan.
"Heard the rumble, felt my chair rock sideways as the wave move through the house," Dennis Speicher, of Enid, wrote on the News & Eagle Facebook page.
On the west side of Enid, Phyllis Logsdon wrote she thought her television was going to fall off its stand.
"In Garber moved through like a wave and hit hard enough to creek the walls and rattle the windows. You could also still hear it as it moved away," Mike Thorp wrote.
Enid residents throughout the city reported shaking, creaking houses.
“Super loud North of Enid,” Sara Mendenhall Gorman wrote on Facebook. “Could hear it coming before it hit. Grandfather clock chimed in its own!”
USGS records show the two quakes are the largest temblors recorded this year in Oklahoma, and only the third measuring magnitude 4.0 or greater. A magnitude 4.0 quake occurred 14 miles east-northeast of Mooreland on Feb. 16.
Since the beginning of the year, there have been 25 magnitude 3.0 or greater earthquakes recorded in the state, according to the USGS. Last year, as of March 4, 2017, there had been 42 magnitude 3.0 or greater quakes.
'Almost as strong'
The second earthquake occurred shortly before press time.
"Almost as strong as first one but don’t think it lasted as long," Kim Mullen wrote from the Indian Hills addition in Enid.
According to the USGS, aftershocks are earthquakes that follow the largest shock of an earthquake sequence. Smaller than the mainshock and within one to two rupture lengths distance from the mainshock, aftershocks can continue over a period of weeks, months or years. In general, the larger the mainshock, the larger and more numerous the aftershocks, and the longer they will continue.
