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 …

Microcracking due to thermal stresses affects the mechanical and flow properties of rocks,
which is significant for thermally dynamic environments such as volcanoes and geothermal …

Since the early 1970s enhanced eruptive activity of Mount Etna has been accompanied by
selective geochemical changes in erupted lavas, among which a gradual increase of alkalis …

We report simultaneous laboratory measurements of seismic velocities and fluid
permeability on lava flow basalt from Etna (Italy) and columnar basalt from Seljadur …

Most flank eruptions within a central stratovolcano are triggered by lateral draining of
magma from its central conduit, and only few eruptions appear to be independent of the …

Abstract In the Central Mediterranean region, the production of chemically diverse volcanic
products (eg, those from Mt. Etna and the Aeolian Islands archipelago) testifies to the …

Volcanic eruptions are fed by plumbing systems that transport magma from its source to the
surface, mostly fed by dykes. Here we present laboratory experiments that model dyke …

The physical integrity of a sub-volcanic basement is crucial in controlling the stability of a
volcanic edifice. For many volcanoes, this basement can comprise thick sequences of …

The 2001 and 2002–2003 Etna eruptions were strongly explosive and their lavas
(trachybasalts and alkali basalts) exhibit quite unusual mineralogy and geochemistry. In …

Volcanic eruptions occur when a conduit forms to connect a crustal magma reservoir to
Earth's surface. Conduit formation is generally assumed to be a 'bottom–up'process and a …
