Simplifying assumptions in volcano modeling: are we missing something crucial?
14 Mar 2014 | Contributor(s):: Chiara Paola Montagna, Antonella Longo, Paolo Papale, Gilberto Saccorotti
Volcanoes are extremely complex natural systems, in which the interplay of different forces and physical processes determines a variety of behaviors that can be hard to interpret. The deep magmatic systems cannot be directly observed, and we must rely on indirect information. The latter typically...
Complex magmatic systems and geophysical signal analysis: what can we understand from inversions?
14 Mar 2014 | Contributor(s):: Chiara Paola Montagna, G. Saccorotti, P. Papale, A. Longo
Many volcanic eruptions are shortly preceded by new magma injection into a pre-existing, shallow (< 10 km) magma chamber, causing convection and mixing between the incoming and resident magmas. These processes may trigger dyke propagation and further magma rise, inducing long-term (days to...
