They can travel through kilometres of rock allowing for a radiography of the density distribution within large structures, like mountains or volcanoes. A collaboration between volcanologists, astroparticle and particle physicists, Tomuvol was formed in 2009 to study tomographic muon imaging of volcanoes with high-resolution, large-scale tracking detectors. We report on two campaigns of measurements at the flank of the Puy de D me using glass resistive plate chambers (GRPCs) developed for particle physics, within the CALICE collaboration. %U http://www.geosci-instrum-method-data-syst.net/2/55/2013/gi-2-55-2013.html
