This study aims to provide decision support for natio celebrate eyeshadow palette future measures to be taken regarding 2 tunnels using high-resolution 3D imaging of the subsurface.This project involves a more comprehensive risk analysis than localized tests, such as geotechnical surveys, and a more precise characterization of the subsoil at the tunnel entrance for approximately 200 meters.To address this issue, a 3D passive seismic tomography was conducted using a click here network installed on the surface of the study area and another in the tunnels to better analyze the subsurface beneath the tunnels.

The 3D shear wave velocity model allowed the identification and delineation of risk zones and the estimation of risk levels based on the analysis of Vs (shear wave velocity) contrasts and their correlation with borehole data.
