Oklahoma Earthquake

 A small tremblor shook Oklahoma shortly after 9 a.m., according to the U.S. Geological Survey.

The Associated Press reports two people in Norman injured by the quake.

Emergency Medical Services Authority spokeswoman Lara O'Leary said one man fell off a ladder during the Wednesday morning quake and is in good condition.

She said she did not have details on the second person's injuries but that the person is in good condition.

It appears the quake was centered 10 miles east of Norman, Oklahoma, just south of Oklahoma City, just off the southeastern shore of Lake Thunderbird.

Early estimates indicate that it measured approximately 4.3 on the Moment Magnitude Scale, which replaced the Richter scale in the 1970s.

There have been no reports of any damage, but calls and emails flooded into the KJRH newsroom within moments of the quake.

Daniel Stines was one of those who wrote into Channel 2 using his News 2 Share tool on his cell phone.

"My bed shook for 3 seconds and the doors and picture shook too. It was crazy feeling. I've been on this earth for 31 years and it's my first earthquake."
