Narrative:

We were cruising over crw at FL250 en route from cle to clt. The first indication of any trouble was a sudden onset of vibration. The first officer and I were searching for the cause, when the lead flight attendant came into the cockpit and announced that the noise and vibration were very loud in the cabin. We found the vibration to be very evident through the right horsepwr lever and noticed that the right turbine gas temperature (tgt) was abnormally high, near the top of the green arc. We pulled the throttle back to idle, the vibration increased, the tgt decreased then increased into the yellow arc. We shut the engine down, declared an emergency and landed at crw. The landing weight was approximately 67500 pounds. The landing and taxi in were uneventful, and the passenger deplaned through the main cabin door. Total single engine time was approximately 15 mins. Callback conversation with reporter revealed the following information: reporter captain verified aircraft type as FA28. Reporter has had no further feedback from company other than it was found that the turbine section had disintegrated.
