The National Institute of Geophysics and Volcanology (INGV) has just released the documents relating to the results of geological and seismological studies conducted on the Sulmona-Foligno gas pipeline route.
These studies were conducted in compliance with the Framework Agreement signed on 6 December 2022 between the Ministry of the Environment and Energy Security (MASE), INGV, and Snam Rete Gas SpA, in which the Institute appears as the "Third Party".
The aim of these investigations was to ensure that the executive design and construction of the project included more precautionary site design spectra than those required by law to protect the public.
In particular, INGV's specialized studies focused on mapping and characterizing seismogenic sources and active and capable faults along the route, assessing seismic hazard using probabilistic and deterministic approaches to ensure the highest levels of safety in relation to the design seismic action, analyzing local seismic response and assessing soil liquefaction susceptibility, and identifying and analyzing landslides potentially interfering with the route.
The documentation is now downloadable at following link.

Figure 1: Satellite image (from Google Earth) showing the distribution of the main seismic faults (colored polygons) identified at or near the pipeline route (black and white lines). The numbers represent the different seismic faults/sources.
Figure 2: Surface acceleration map along the Sulmona-Foligno pipeline obtained by interpolating the results of local seismic response analyses. The black dots represent the locations of the down-hole, cross-hole, and integrative models used for the local seismic response analyses. The color scale is proportional to the Peak Ground Acceleration (PGA) value obtained, expressed in g.
