In recent years, more and more attention has been paid to creating safeguards measures in protecting masterpieces, art items, large statues, from the uncontrollable event of an earthquake. In the poster presented here a specific research about this subject will be brought to the attention of the conference participants: It will be shown how, from a set of significant statues from the Bargello Museum in Florence, Italy, it is possible to define a working model for simulating the effects of an earthquake and understand the real state of safety of these artworks. While the correct definition of the shape of the elements is fundamental in this processing, a particular attention will be given to the phase of digital survey, here operated using photogrammetry based on Structure from Motion procedures. All the steps of the workflow will be analyzed and described in its main issues, lessons learned, new procedures. A set of different procedures will be compared, a speditive method based on a smartphone camera and quick and simple modeling to one based on a 50 Mp resolution camera with high quality optic and highly accurate modeling. The result of the two procedures will be matched to the results of the simulation analysis, suggesting affordable approaches for any similar conditions about the interpretation of the state of safety of this important cultural heritage.
