Following the concept that structures move because something causes their movement, in the paper, the authors analyze interferometric satellite Line-of-Sight displacement acquired over the territory of Rome (Italy) during the period 2011–2019 from a spectral point of view. To obtain a comprehensive understanding of the behavior of civil structures in this unusual frequency bandwidth (~2–200 nHz), an in-depth analysis of the possible sources of perturbation is called into question.
To reach this goal, the difference in the vibration characteristics of measured Line-of-Sight displacements and spectral entropy is studied. The main environmental effects that could affect the built environment (e.g., temperature, hydraulic balance, etc.) are also analyzed in terms of the power spectrum and spectral entropy. The main frequencies associated with both environmental data and remote displacements are highlighted.
A more in-depth knowledge of the inputs of a system would allow to perform more significant virtual experiments or numerical predictions, also contemplating new sources of excitation for civil structures at nanohertz.
