From: Muographic monitoring of the volcano-tectonic evolution of Mount Etna
2018 muography of Etna volcano North-East crater. The image shows a map of the ratio R of muon flux through the mountain to that coming from the open-sky, i.e. without attenuation. R values are displayed as a function of X and Y displacements, Δx and Δy, between the entrance and exit coordinates of muon tracks in the telescope external planes.
