“…GCRs are de ected during their propagation in the galaxy and lose their initial directional information before arriving the Earth; therefore, they uniformly precipitate onto the Earth. A technique called muography uses muons to visualize the internal structure of gigantic objects, taking advantage of the muon's universality and their relativistic (hence, penetrative) nature; muography has been applied to many large structures including volcanoes in Europe 22,23,24 , the Americas 25,26,27 , and Asia 28, 29,30,31,32,33,34,35 , tectonics 36,37 earthquake remnants 38 , tsunami 39 , cyclones 40 , social infrastructure 41 and cultural heritage in Africa 42 , Europe 43,44 and Asia 37 as well as to muometric positioning 45 , navigation 46 , timing 47 , and post-quantum cryptography 48 .…”
