Magma transport in brittle rock occurs by diking. Understanding the dynamics of diking and
its observable consequences is essential to deciphering magma propagation in volcanic …

Magma is transported and stored in the crust mostly through networks of planar structures
(intrusive sheets), ranging from vertical dykes to inclined sheets and horizontal sills, and …

Crystals formed prior to a volcanic event can provide evidence of processes leading to and
timing of eruptions. Clinopyroxene is common in basaltic to intermediate volcanoes …

A correct description and quantification of the geochemical behaviour of REE+ Y (rare earth
elements and Y) and HFSE (high field strength elements) is a key requirement for modeling …

Magma ascent velocities, v (d H/dt; where H is depth and t is time), can be determined from
decompression rates (d P/dt), and rates of cooling (d T/dt):, where ρ is magma density, P is …

Volcano deformation may occur under different conditions. To understand how a volcano
deforms, as well as relations with magmatic activity, we studied Mt. Etna in detail using …

Many volcanic hazard factors-such as the likelihood and duration of an eruption, the
eruption style and the probability of its triggering large landslides or caldera collapses-relate …

Mafic alkaline magmas, such as those feeding the persistent eruptive activity of Stromboli
and Mt. Etna volcanoes in Italy, are dominated by the crystallization of plagioclase via …

Oceanic crust is accreted through the emplacement of dikes at spreading ridges, but the role
of dike intrusion in plate boundary deformation during continental rupture remains poorly …

Collapse calderas are frequent in the evolution of volcanic systems, but very few have
formed during historical times. Piton de la Fournaise is one of the world's most active …
