[automatically translated] The suspicion that the extraordinary and unusual documentation produced at the Palermo of 1726 earthquake - four printed reports published by the Senate of the city in a few months and several planimetric representations, including recordings, handwritten cards and oils, showing the damage caused by the earthquake - concealed in reality the plots of a calculated political strategy called for a new and objective investigation into the affair to be conducted through the collection and the reorganization of the wealth of sources preserved in the archives of Palermo. From that critical reassessment has surfaced so the story of a deep contrast and a hard tug of war between the two most important administrative institutions of the city, the Senate of Palermo and the Court of Real Estate which has enabled to reconstruct the dynamics of events and to properly understand the meaning of so many and incisive communication tools. In this new interpretative framework the aspect that is of greater interest on the historical and scientific level consists of the planimetric representations of the city produced on the occasion of the tragic event: in fact turns out to be the first time in the history of seismology not only in Sicily, which makes use the cartographic support not only to locate survey-accurate damage but above all to illustrate the causes that had provoked them. Of these, is the handwritten paper drawn up a month after the earthquake by Domenico Campolo, the main architect of the operation mapping, offering the greatest contribution in terms of innovation and scientific content; with it the author, through a unique graphic processing of the effects of an earthquake on the building structures beds in relation to the consistency and stability of the foundation soils, denounced the close relationship between the geological nature of the soil and the extent of the damage caused, thus providing a novel analytical model representation and an archetype of modern seismic mapping.
