Narrative:
We were climbing to our cruise altitude when the #1 engine vibration indicator rose into the yellow. We performed the QRH procedure and shut down the #1 engine. It stayed in the yellow on the vibration indicator at idle so the QRH called for shutdown. We declared an emergency. We continued the QRH procedure and an item was 'did we suspect severe engine damage.' there weren't any vibrations or sounds from the engine. So we decided 'no' there was not suspected severe engine damage. So we followed the QRH into a re-light. The engine started normally and continued to operate without any abnormal vibration indications. We canceled the emergency with ATC and continued uneventfully to our destination.
