Supplementary_material_Editorial_Porfido et al_2022.

As supplementary material we propose a publication, in which there is the first preliminary attribution of macroseismic intensity for the 1980 earthquake: "Il terremoto del 23-11-1980. Rilievo Macrosismico Stato di Avanzamento al 27-1-1981" [29] and some topographic maps of the effects induced by the 1980 IrpiniaLucania earthquake, which were plotted in the field. Soon after the November 23, 1980 Irpinia - Lucania earthquake, several groups of geologists of the CNR-PFG projects, mapped the coseismic geological effects in a wide portion of the epicentral area. We include some of the original sketch of topographic maps (form 1:25.000 topographic maps of Istituto Geografico Militare, I.G.M., 1955) saved as a historical record of the time, that the Professor Paolo Scandone, as leader of PFG project, made available many years after the earthquake on which the coseismic effects of the 1980 earthquake were mapped. On the excerpts of the topographic maps mainly earthquake-induced fractures are shown, and in some cases it has been marked occurrence of landslides as well as portions of earthquake-induced faults. Although it must be pointed out that many researchers at the time did not believe that these faults were of tectonic origin but ascribed all of them either to pure gravitative sliding or to debris compactation [11]. Only a few Italian researchers interpreted as due tectonic origin the fractures occurred along the Piano di Pecore on Mt. Marzano (186 Colliano IISW), or Sele Valley and at Pantano di S. Gregorio Magno (198 Buccino, I, NE; 199 Vietri di Potenza, IV, NW) [9,10], as later documented by several researchers who reconstructed the end to end seismogenic fault segments [12-17]. As supplementary material, the following are the cartographic union framework of the 1: 25,000 topographic maps attached and the extracts of these maps on which are mapped the coseismic effects detected during the field survey:
