OKLAHOMA CITY (AP) — Authorities say a 5.6 magnitude earthquake has hit central Oklahoma, but they had no immediate reports of any injuries or major damages.
The U.S. Geological Survey reported from Golden, Colorado, on its website that it detected a 5.6 magnitude quake at 10:53 p.m. local time Saturday (0353 GMT Sunday), centered about 44 miles (71 kilometers) east-northeast of Oklahoma City. It had initially reported the temblor as a 5.2 magnitude quake.
Michelann Ooten, a spokeswoman for the Oklahoma Department of Emergency Management, also confirmed a quake on the scale of 5 was recorded.
It came on a day a series of quakes rattled the state, including a 4.7 magnitude quake early Saturday.
Ooten said no injuries were reported to emergency management officials and she had no reports of major damage.

 very strong shallow earthquake occurred at 03:53 at almost the same area than earlier this morning. We are currently looking for more information
Update 05:12 UTC : It was felt in not only in Oklahoma but also in Arkansas, Texas, Missouri and Kansas. There are even some reports of the quake being felt in Illinois. There have been nine earthquakes recorded in Oklahoma in the past 24 hours with the 5.6 being the largest.
Update 05:09 UTC : We repeat that the extreme theoretical MMI shaking numbers are NOT reflected on the really Felt shaking map. This is a good sign.
Update 05:06 UTC : The extremely shallow depth (if confirmed), makes it feel like an explosion almost below your house.  A radius of 20 km is most at risk for damage and/or injuries in this case.
Update 05:03 UTC : The first news tends to be good – NO report of killed or badly injured people yet. This is lin line with the I Have Felt It map from above. Damage on the other hand will certainly be inflicted.
Update 04:55 UTC : After looking into the earthquake data which have been reported by people to the USGS, we predict that the expected damage will be less than initially thought with this heavy shaking. Even in the direct epicenter area, only a moderate to max. strong shaking has been reported
Update : Tulsa’s Channel 8 has received photos of damage from the quake at 71st and Garnett in Tulsa. This is in earthquake terms very far from the epicenter, which makes us believe that other damage will be reported too
Update : So far we have NOT seen any reports on damage or injuries, but we are convinced that they will appear gradually a little later
Update : This earthquake is the largest ever recorded in the state’s history.
Update : The new magnitude does not exclude serious damage or injured people. It will be anxiously waiting for the first reports of emergency services.
Update :
55 people will have felt a VIOLENT shaking
1,000 people will have felt a SEVERE shaking
19,000 people will have felt a VERY STRONG shaking51,000 people will have felt a STRONG shaking

The earthquake has been updated by USGS to a 5.6 magnitude earthquake,  this changes the outcome from this earthquake completely
