SUMMARY:Inside Volcanoes through cosmic-ray muon tomography
DESCRIPTION:Inside Volcanoes through cosmic-ray muon tomography\nDr. Seigo 
 Miyamoto, Dr. Valeri Tioukov\n\nThe origin and structure of the Earth's cr
 ust is still a major question.  Current measurements of the nearby crust a
 re based largely on seismic,  gravimetric and electrical  techniques.
  In this talk, we introduce a  novel method based on cosmic-ray muons to c
 reate a direct snapshot of  the density profile within a volcano (and/or o
 ther geological  features).  By measuring the muon absorption along t
 he different paths through an object (volcano,  mountain, a fault, ...), o
 ne can deduce the density profile within the  object. The major feature of
  this technique makes possible for us to perform a tomographic measurement
  by placing two or more cosmic ray detection systems around the object. An
 other strong point of this technique is  the possibility to carry out full
 time monitoring, since  muons are  incessantly arriving, recalling th
 ey are the most numerous energetic charged particles at sea level.
