The earthquake that shook Kansas and four other states this morning was one of the strongest ever recorded in Oklahoma.

The earthquake struck at 9:06 a.m. about six miles east of Norman. At least two people sustained minor injuries. Minor damage — primarily to windows and fallen items — was reported.

"You definitely would have felt it in Wichita," said Don Blakeman, a geophysicist with the U.S. Geological Survey's earthquake information center in Golden, Colo.
