RT Journal Article T1 A free boundary problem related to the location of volcanic gas sources A1 Díaz Díaz, Jesús Ildefonso A1 Talenti, Giorgio AB A mathematical model of general gas emitting systems is derived, and a sample of relevant mathematical results is offered. The present paper indicates that shallow subsurface gas sources in typicalvolcanic areas can be located if appropriate physico-chemical measurements are made on the Earth’s surface and put to use.
