Tuesday March 3, starting 9 pm: 30, will be held in Bojano (CB) the presentation of the results of the multidisciplinary project MOSAICMO (MOlise SANnio Integrated Crustal MOdel) ofNational Institute of Geophysics and Volcanology (INGV)The event, organized with the municipal administrations of Bojano and San Massimo (CB), will take place at Palazzo Colagrosso and will be open to the public.
The project, characterised by an integrated geological, geophysical and seismological study and financed under Dynamic Planet 2023-2025, has deepened his knowledge of the territory of Sannio-Matese and the Bojano Basin, located at the junction of the central and southern Apennines and characterized by high seismic hazard. Given its interdisciplinary nature, It saw the collaboration not only of researchers from numerous INGV sections, but also of the Universities of Molise, Bari, Naples, Pisa, Geneva and the National Research Council (CNR).
The MOSAICMO project has pursued, throughout its history, a dual objective: on a regional scale, improve knowledge of the structure of the Earth's crust and the seismotectonic characteristics of the area; on a local scale, Create a geological and geophysical model of the Bojano Basin to reconstruct its tectonic evolution and understand its seismic response.The area, in fact, is bordered by fault systems that in the past have generated strong earthquakes, such as the 6.7 magnitude one of 1805.
During the project, numerous data acquisition campaigns were conducted – geophysical, seismological, geological and geochemical, at regional and local levels. These investigations allowed us to: develop 2D and 3D geological and geophysical models of the Earth's crust in the Sannio Matese area, as well as identifying active faults thanks to the analysis of seismicity recorded for 24 months by a temporary seismic network.
In the Bojano Basin, the study integrated advanced geophysical techniques, which allow for detailed images of the subsoil, with the implementation of a scientific survey. The drilling allowed for continuous sampling of sediments that fill the basin, of alluvial and marshy origin, accumulated over hundreds of thousands of years, reaching even the oldest bedrock at a depth of 140 to 175 meters. Integrating the data collected during this phase with two- and three-dimensional geophysical models, extending to a depth of 500 meters, has allowed us to reconstruct the composition, physical characteristics, and age of the basin's fill sediments, as well as identify the active faults that controlled its tectonic evolution.
The study's findings could contribute to improving knowledge of the area's groundwater, as well as the seismic amplification phenomena within the basin, providing more useful insights for land management.
