Session 1.2 GNGTS 2023 Fig. 2 – a) Three-dimensional model of the most superficial part of the Moho; b) Visualization of the three-dimensional Moho model of Central Mediterranean that allows to observe the Ionian slab. Fig. 3 – Comparison between the Ionian slab proposed by DISS (surface represented in grey scale) and that proposed by us (surface represented in color scale). The seismic events plotted are related to the period from 2005 to 2022, M>4 and depth > 40 km. CONCLUSION The joint use of one-dimensional and two-dimensional data of different kinds has allowed to obtain a detailed three-dimensional model of the topography of Moho in the Central Mediterranean area. This model will allow a better understanding of the structure of the upper mantle and will contribute to the understanding of the complex geodynamics of the area. In addition, the model can be easily updated: new data, such as tomography, seismic, gravity and velocity profiles, will be useful to perfect the model in its most superficial portion while new seismic events and a relocation of past ones will be of great help to perfect the model in its deepest portion.
