Abstract La Soufri’ere de Guadeloupe is an active volcano of the Lesser Antilles Volcanic Arc. Its last eruption halted in 1977, yet hydrothermal activity has increased over recent years, raising summit instability hazards. The link between hydrothermal fluids and detachment landslide surfaces is well established and exacerbated by inflation, pressurization, and fluid flow lubrication. Nodal Ambient Noise Tomography offers the resolution and penetration needed to investigate such features in 3D. In 2023, we deployed 39 nodal geophones that recorded for about 1 month. The resulting 3D S‐wave velocity model resolves a central low‐velocity conduit, possible flank detachment planes, and subsurface structures of the shallow volcanic cone. Our results highlight the complex interaction between fluid transport (meteoric and magmatic) and tectono‐magmatic drivers. This provides the first high‐resolution 3D seismic imaging for slope stability assessment in volcanic environments. Understanding detachment zone geometry and distribution contributes to hazard risk assessment and mitigation.
