We present density radiographies obtained for the Soufrière of Guadeloupe lava dome, both in the North-South and East-West planes. These radiographies reveal the highly heterogeneous density structure of the volcano, with low-density regions corresponding to recognized hydrothermally altered areas. The main structures observed in the density radiographies correlate with anomalies in electrical resistivity cross-sections and seismic velocity model.
