Narrative:
As we approached initial cruise altitude; a right engine high vibration message illuminated. We completed the QRH procedure; and retarded the throttle to idle. The flight attendants reported unusual vibrations at the back of the aircraft. We consulted with company maintenance and flight control and the flight was diverted to ZZZ. The approach and landing were normal. No emergency was declared. The flight was scheduled ZZZ1 to ZZZ2 service.

Title: AN MD80 FLT CREW EXPERIENCED HIGH ENG VIBRATION AT 30000 FT. THEY FOLLOWED THE QRH; REDUCED THRUST TO IDLE; COORDINATED WITH MAINT AND DISPATCH; AND DIVERTED TO THE NEAREST SUITABLE AIRPORT.
Narrative: AS WE APCHED INITIAL CRUISE ALT; A R ENG HIGH VIBRATION MESSAGE ILLUMINATED. WE COMPLETED THE QRH PROC; AND RETARDED THE THROTTLE TO IDLE. THE FLT ATTENDANTS RPTED UNUSUAL VIBRATIONS AT THE BACK OF THE ACFT. WE CONSULTED WITH COMPANY MAINT AND FLT CTL AND THE FLT WAS DIVERTED TO ZZZ. THE APCH AND LNDG WERE NORMAL. NO EMER WAS DECLARED. THE FLT WAS SCHEDULED ZZZ1 TO ZZZ2 SVC.
