Oklahoma Hit With 10 Aftershocks Following 5.6-Magnitude Earthquake

Earthquake buckled highway, cracked buildings, but left residents virtually unscathed.

SPARKS, Okla. – Oklahoma residents more accustomed to tornadoes than earthquakes have been shaken by weekend temblors that cracked buildings, buckled a highway and rattled nerves. One quake late Saturday was the state's strongest ever and jolted a college football stadium 50 miles away.

It was followed by 10 aftershocks by midmorning Sunday. But although homes and other buildings cracked and suffered minor damage, there were no reports of severe injuries or major devastation.

Saturday night's earthquake jolted Oklahoma State University's stadium shortly after the No. 3 Cowboys defeated No. 17 Kansas State.

"That shook up the place, had a lot of people nervous," Oklahoma State wide receiver Justin Blackmon said. "Yeah, it was pretty strong."

The magnitude 5.6 earthquake was Oklahoma's strongest on record, said Jessica Turner, a geophysicist with the U.S. Geological Survey. Centered near Sparks, 44 miles northeast of Oklahoma City, it could be felt throughout the state and in Arkansas, Kansas, Missouri, northern Texas and some parts of Illinois and Wisconsin. It followed a magnitude 4.7 quake early Saturday that was felt from Texas to Missouri.

The aftershocks included two that were magnitude 4.0, one about 4 a.m. Sunday and one about 9 a.m., USGS said. The smallest aftershock it recorded was magnitude 2.7. USGS seismologist Paul Earle in Golden, Colo., said the aftershocks will likely continue for several days and could continue for months.

Oklahoma typically has about 50 earthquakes a year, and 57 tornadoes, but a burst of quakes east of Oklahoma City has contributed to a sharp increase. Researchers said 1,047 quakes shook Oklahoma last year, prompting them to install seismographs in the area. The reason for the increase isn't known, and Turner said there was no immediate explanation for the weekend spurt in seismic activity.

Whole Lotta Shakin' Going On !!! Damage Reported After 5.6 Magnitude Earthquake Strikes Oklahoma

SPARKS, Okla. – Oklahomans more accustomed to tornadoes than earthquakes suffered through a weekend of temblors that cracked buildings, buckled a highway and rattled nerves. One quake late Saturday was the state's strongest ever and jolted a college football stadium 50 miles away and was followed early Sunday by a jarring aftershock.

There were no reports in the hours after the quakes of any severe injuries or major devastation.

"That shook up the place, had a lot of people nervous," Oklahoma State wide receiver Justin Blackmon said of the late Saturday quake, the strongest of a series of quakes. "Yeah, it was pretty strong."

The magnitude 5.6 earthquake Saturday night was centered near Sparks, 44 miles northeast of Oklahoma City, and could be felt throughout the state and in Kansas, Missouri, Arkansas, northern Texas and some parts of Illinois and Wisconsin, said geophysicist Jessica Turner at the U.S. Geological Survey. A magnitude 4.7 quake early Saturday was felt from Texas to Missouri.

Turner told The Associated Press that the subsequent magnitude 4.0 quake that struck at 3:39 a.m. Sunday was an aftershock centered some 36 miles east of Oklahoma City in the same region. Like Saturday night's quake, she said it was another shallow quake occurring about 3 miles underground, but experts had no immediate explanation for the spurt in seismic activity.

Following the quakes or numerous small aftershocks, several homeowners and businesses reported cracked walls, fallen knickknacks and other minor damage. But in Shawnee, the fire department said one spire on the administration building at St. Gregory University had been damaged and another one was leaning, according to KWTV in Oklahoma City.

An emergency manager in Lincoln County near the epicenter said U.S. 62, a two-lane highway that meanders through rolling landscape between Oklahoma City and the Arkansas state line, crumpled in places when the stronger quake struck Saturday night. Other reports Sunday were sketchy and mentioned cracks in some buildings and a chimney toppled.

"Earthquake damage in Oklahoma. That's an anomaly right there," Todd McKinsey of Moore told The Oklahoman newspaper after the magnitude 5.6 temblor centered 50 miles away left him with cracked drywall.

Oklahoma typically has about 50 earthquakes a year, and 57 tornadoes, but a swarm of quakes east of Oklahoma City contributed to a sharp increase in the number of temblors. Researchers said 1,047 quakes occurred last year, prompting them to install seismographs in the area. A cause of the uptick wasn't known.
