Magma mixing dynamics and associated geophysical signals
08 Oct 2015 | Contributor(s):: Chiara Paola Montagna, Antonella Longo, Paolo Papale, Matteo Bagagli
Primitive, volatile-rich magma arrival from depth into a degassed, evolved reservoir at 3km depth is investigated. The two magmatic end-member mix very efficiently on time scales of hours. The evolution is characterized by very heterogeneous pressure variations in space and time, showing...

Timescales of mingling in shallow magmatic reservoirs
12 Jun 2015 | Contributor(s):: Chiara Paola Montagna, paolo papale, antonella longo
Arrival of magma from depth into shallow reservoirs has been documented as one of thepossible processes leading to eruption. Magma intruding and rising to the surface interacts with thealready emplaced, degassed magmas residing at shallower depths, leaving chemical signatures inthe erupted...

Geophysical signatures of magma chamber replenishment
14 Mar 2014 | Contributor(s):: Antonella Longo, Chiara Paola Montagna, Gilberto Saccorotti, Paolo Papale
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...
Magma flow between summit and Pu`u `O`o at Kilauea volcano, Hawai`i
14 Mar 2014 | Contributor(s):: Chiara Paola Montagna, Helge Gonnermann
Volcanic eruptions are often accompanied by spatiotemporal migration ofground deformation, a consequence of pressure changes within magma reser-voirs and pathways. We model the propagation of pressure variations byeruptive magma withdrawal during the early episodes of the ongoing Pu‘u ̄...
