CNBC: Strong Oklahoma earthquake felt from Nebraska to Texas
One of the largest earthquakes in Oklahoma rattled the Midwest on Saturday from Nebraska to North Texas, according to CNBC.
The United States Geological Survey said a 5.6 magnitude earthquake happened at 7:02 a.m. Saturday in north-central Oklahoma, a key energy-producing region, CNBC said.
That matches a November 2011 quake in the same region. No major damage was immediately reported.
People in Kansas City and St. Louis, Missouri; Fayetteville, Arkansas; Des Moines, Iowa; and Norman, Oklahoma, all reported feeling the earthquake. Dallas TV station WFAA tweeted that the quake shook their studios, too.

State regulators have asked producers to reduce wastewater disposal volumes in earthquake-prone regions of the state. Some parts of Oklahoma now match northern California for the nation's most shake-prone, and one Oklahoma region has a 1 in 8 chance of a damaging quake in 2016, with other parts closer to 1 in 20.
A cluster of quakes in northwestern Oklahoma this year included a magnitude 5.1 earthquake, and several 4.7 quakes were felt last fall before regulators stepped in to limit disposal activity.
Saturday's quake was centered about 9 miles northwest of Pawnee, Oklahoma. Earlier this week, the same spot, which is about 70 miles northeast of Oklahoma City, saw a magnitude 3.2 temblor.
