Story highlights"All the houses look like they've been ransacked," official says Several houses are
damaged One man suffers minor injuries, an official saysThe strongest quake in the area until now
was on April 9, 1952Central Oklahoma continued to experience dozens of aftershocks Sunday, nearly
24 hours since the state's strongest earthquake since 1952 was felt throughout the region.
More than ten aftershocks measuring at east 3.0 magnitude were reported Sunday, in the hours
after a 5.6-magnitude earthquake took residents by surprise Saturday night. The temblor rattled
homes and structures, causing belongings to scatter in houses and sending strident, booming sounds
through the area.
Kathy Crawson, a nurse with a community hospital in Prague, Oklahoma, about six miles from the
quake's epicenter, said Sunday the experience was terrifying, but she was getting used to the
aftershocks.
"We have felt several aftershocks. I just felt one a few minutes ago," said Crawson.
The 5.6-magnitude quake struck four miles east of Sparks in Lincoln County at 11:53 p.m. ET
Saturday.
It hit struck the same area where a 4.7-magnitude http://news.sky.com/ quake struck just hours
earlier -- at 3:12 a.m. ET Saturday.
By 8 a.m. Sunday, geologists had recorded more than 30 aftershocks.
The strongest quake previously reported was of magnitude 5.5 on April 9, 1952, according to the
Oklahoma Geological Survey.

2. According to The search engines Oklahoman newspaper, the weekend's tremors were reportedly felt
as far away as Illinois, Kansas, Arkansas, Tennessee and Texas.
Some 200 miles away from the epicenter, in Garland, Texas, resident Noel Kennedy said he felt the
quake.
Austin Holland, a seismologist with the state geological survey, said he spent all day gathering new
data from seismological instruments.
"We have experienced over 10 aftershocks above 3.0," said Holland.
The quakes happened near the location of a 4.7-magnitude quake last year near the Wilzetta fault,
also known as the Seminole uplift, Holland said.
"Being from Oklahoma, I had never experienced anything since last year. It's a wild, strange feeling.
You can actually see it, the walls, the floors, the noise. I was scared," nurse Crawson, of Prague, said
Sunday.
While last year's quake indicated there was new seismic activity in the area, Holland said he was
surprised by "the 5.6."
According to the OGS website, the frequency of earthquakes has temporarily increased in Oklahoma
but are not inconsistent with normal seismicity in the region.
In 2010, the OGS recorded 1,047 earthquakes in Oklahoma -- most of them small temblors, but 103
were reported felt, the agency said..
Crews continue to assess damage Sunday. No major injuries were reported, but the quake caused at
least three sections of U.S. Route 62 to buckle, said Aaron Bennett of Lincoln County emergency
services.
Crews reported some structural damage, including a roof collapse and a damaged ventilation system
in a municipal building.
"They're reporting that all the houses look like they've been ransacked," Bennett said of the
assessment crews.
At least one person was taken to a hospital in Prague with minor injuries, he said.
The man hit his head against a wall when he tripped and fell while trying to run out of his house,
Bennett said.
In Broken Arrow, resident Bubba Fernandez estimated that the ground shook for a full minute when
the quake struck.
"It was at least a minute," Fernandez told CNN affiliate KTUL. "Upstairs, my kid's trophy, the piano
upstairs, the little tassels on the fan -- it was at least a minute"
While the continuous aftershocks are expected, Holland said, predicting a quake is nearly
impossible.

3. "Oklahoma is not on active plate like Haiti and other earthquake-prone regions," said Holland.
"We know that this is an old fault, now reactivated, interacting with the North American plate and
generating pressure," said Holland.
"What we can do is use and learn from these instruments so we can make decisions for the future,"
he said.
