This introductory article provides a synopsis of our current understanding of the form and
dynamics of magma reservoirs in the crust. This knowledge is based on a range of …

We use both seismology and geobarometry to investigate the movement of melt through the
volcanic crust of Iceland. We have captured melt in the act of moving within or through a …

Magma supply from the lower crust is often proposed as a trigger mechanism for volcanic
eruptions. The timescales over which magma can be transported from the deepest parts of …

Large volume effusive eruptions with relatively minor observed precursory signals are at
odds with widely used models to interpret volcano deformation. Here we propose a new …

Abstract The 2014–2015 Holuhraun eruption, on the Bárðarbunga volcanic system in central
Iceland, was one of the best-monitored basaltic fissure eruptions that has ever occurred, and …

Maximum depths of earthquakes in different settings are commonly thought to lie within a
transition, many kilometers in width, from brittle deformation at shallow depths to plastic …

Over 2 weeks in August 2014, magma propagated 48 km laterally from Bárðarbunga
volcano before erupting at Holuhraun for 6 months, accompanied by collapse of the caldera …

The 2014–2015 Holuhraun fissure eruption provided a rare opportunity to study in detail the
magmatic processes and magma plumbing system dynamics during a 6-month-long …

The mass of volatiles emitted during volcanic eruptions is often estimated by comparing the
volatile contents of undegassed melt inclusions, trapped in crystals at an early stage of …

We use a dense seismic network on the Reykjanes Peninsula, Iceland, to image a group of
earthquakes at 10–12 km depth, 2 km north-east of 2021 Fagradalsfjall eruption site. These …
