| Zusammenfassung |
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. |
