“…It started in 2008 with a collaboration between three French institutes: IPG Paris, IPN Lyon and Gé osciences Rennes to promote muon tomography in the French Earth Science and Particle Physics communities [8]. The first objectives of the project were to make technological choices for the muon telescopes and to define a design suitable for the difficult field conditions encountered on the Lesser Antilles volcanoes.…”

Imaging the inner part of large geological targets is an important issue in geosciences with various applications. Dif- ferent approaches already exist (e.g. gravimetry, electrical tomography) that give access to a wide range of informations but with identified limitations or drawbacks (e.g. intrinsic ambiguity of the inverse problem, time consuming deployment of sensors over large distances). Here we present an alternative and complementary tomography method based on the measurement of the cosmic muons flux attenuation through the geological structures. We detail the basics of this muon tomography with a special emphasis on the photo-active detectors.Comment: Invited talk at the 6th conference on New Developments In Photodetection (NDIP'11), Lyon-France, July 4-8, 2011; Nuclear Instruments and Methods in Physics Research Section A, 201

“…Given the constant erosion of the volcano due to the tropical intensive rain activity, the evolution of such a lacunary structure may be rapid, with cavities filled with pressurized and likely acid fluids. These features, which are common to many tropical volcanoes, lead to the choice of the Soufrière of Guadeloupe as a priority target [8].…”

Muon tomography is a generic imaging method using the differential absorption of cosmic muons by matter. The measured contrast in the muons flux reflects the matter density contrast as it does in conventional medical imaging. The applications to volcanology present may advantadges induced by the features of the target itself: limited access to dangerous zones, impossible use of standard boreholes information, harsh environmental conditions etc. The Diaphane project is one of the largest and leading collaboration in the field and the present article summarizes recent results collected on the Lesser Antilles, with a special emphasis on the Soufrière of Guadeloupe.

“…Radiographic measurements (Tanaka and Yokoyama, 2008;Tanaka et al, 2005Tanaka et al, , 2007Tanaka et al, , 2009a and even a tomographic imaging (Tanaka et al, 2010) have already been carried out on small volcanoes in Japan. In addition, a recent study makes a first comparison of muon radiography results (Gibert et al, 2010;Marteau et al, 2012) with other geophysical data for la Soufrière de Guadeloupe volcano .…”

Abstract. Muon imaging of volcanoes and of geological structures in general is actively being developed by several groups in the world. It has the potential to provide 3-D density distributions with an accuracy of a few percent. At this stage of development, comparisons with established geophysical methods are useful to validate the method. An experiment has been carried out in 2011 and 2012 on a large trachytic dome, the Puy de Dôme volcano, to perform such a comparison of muon imaging with gravimetric tomography and 2-D electrical resistivity tomography. Here, we present the preliminary results for the last two methods.North-south and east-west resistivity profiles allow us to model the resistivity distribution down to the base of the dome. The modelling of the Bouguer anomaly provides models for the density distribution within the dome that are directly comparable with the results from the muon imaging. Our ultimate goal is to derive a model of the dome using the joint interpretation of all sets of data.
