Tracking the 2007–2023 magma-driven unrest at Campi Flegrei caldera (Italy)
Communications Earth & EnvironmentUnderstanding and managing unrest at a volcano include i) ascertaining the magmatic distribution and migration, and ii) tracking the evolution of the shallow plumbing system.

VolcanicaThe eruptive style of magma is shaped by both storage conditions and ascent processes. Peralkaline melts, with relatively high water concentrations and low viscosity, are expected to better resist magmatic fragmentation compared to peraluminous melts ...

Manner of magma ascent at Unzen Volcano (Japan)
Geophysical Research Letters, 1995 Juvenile materials were found among products of phreatomagmatic eruptions that preceded dacite dome growth at Unzen Volcano in 1991. They give evidence showing that the hydrous magma started degassing with the resultant crystallization around 100 MPa, and was quenched soon thereafter.

Tectonic stress controls on ascent and emplacement of magmas
Journal of Volcanology and Geothermal Research, 1999 Abstract The tectonic stresses can significantly affect the propagation of a magma-filled crack. It has been pointed out that the rheological boundaries control the emplacement of magmas through the effect of stress. However, it has not been clarified how the role of rheological boundaries depends on the regional tectonic and thermal states.

Processes of granite emplacement: NW Ireland and SE Brazil [PDF]
, 1997 This thesis is a study of some of the processes which operate at mid crustal levels (10- 20km) during the emplacement of granitoid magmas, with particular reference to the process of in-situ expansion and the association between magma emplacement and ...

RIFTING TECTONICS AND MAGMA ASCENT
, 2005 [1] The Neapolitan volcanic region is located within the graben structure of the Campanian Plain (CP), which developed between the western sector of the Appenine Chain and the eastern margin of the Tyrrhenian Sea. Two volcanic areas, spaced less than 10 km apart, are situated within the CP: the Somma-Vesuvius Volcano (SVV) and the Phlegraean Volcanic ...
