With the objective of characterizing the dynamic behavior of the Aureliana Column in Rome and evaluating its health status, an ambient vibration survey of the monument was carried out by using nine Kinemetrics seismometers SS-1 connected to one Kinemetrics K2 recorder. Data were analyzed both in time and frequency domain. The analysis showed that the motion was governed by two quite close translational frequencies, equal to 1.24 and 1.3 Hz respectively, and also by a third translational frequency, equal to 6.5 Hz. A rotational frequency, equal to 9.0 Hz was also observed. The analysis of the curves described by the measurement point at the top of the tower gave interesting information about the characteristics of the column vibrations, which does not behave as a whole.
