PROBLEM TO BE SOLVED: To provide a long period earthquake control operation system for an elevator capable of suitably controlling a plurality of existing elevators even when power failure occurs during control operation performed when the long period earthquake is generated and preventing catch of a rope and equipment damage caused by the long period earthquake. SOLUTION: The elevator long period earthquake control operation system is provided with a long period earthquake sensor 10 for detecting a predetermined long period earthquake; a control operation control means 13 for performing control operation based on the detection result of the long period earthquake sensor 10 and landing the cars of the respective elevators at a predetermined halt story; and an electricity returning means 12 for feeding electric power required for operation of the elevator in generation of power failure. Further, the control operation control means 13 successively lands the elevator in which the car is stopped at a position near a predetermined resonance story at the halt story after electricity-recovery by the electricity recovery means 12 when power failure is generated during the control operation.
