PROBLEM TO BE SOLVED: To provide an earthquake time control operation device for an elevator for setting a range of allowance time from a time point receiving an emergency earthquake flash report to arrival of a principal motion (S-wave) of seismic wave and conducting controlled operation to a safer floor having higher priority corresponding to the allowance time. SOLUTION: Earthquake sensors 8, 9 mounted in the elevator, an elevator control device 2 for controlling operation of the elevator and an earthquake information receiving means 10 for receiving the emergency earthquake flash report are provided and, when the earthquake information receiving means receives the emergency earthquake flash report, the elevator control device calculates the allowable time from receipt of the emergency earthquake information to arrival the earthquake wave by the S-wave (the principal motion), priority of evacuation floors according to a building specification is preset, travelling time of the elevator in a travelling state to each evacuation floor is calculated from the travelling state of the elevator, an evacuation floor is determined from the allowable time and the travelling time to each evacuation floor and thus controlled operation to a safer floor of high priority is conducted.
