Evidence for large amounts of melt beneath Ciomadul (Romania), a supposedly extinct volcano ! 


  • Petrological observations infers a trans-crustal magmatic system beneath Ciomadul
  • Thermal evolution of such magmatic system predicts the persistence of melt
  • In situ measurements confirm the presence of about 30% of hydrous melt under the volcano
  • Ciomadul lies above a long-term storage just above the solidus for prolonged periods
  • Volcano status must be defined based on the magmatic reservoir storage conditions
