INTRODUCTION The Bárdarbunga caldera volcano in central Iceland collapsed from
August 2014 to February 2015 during the largest eruption in Europe since 1784. An ice-filled …

On ocean basaltic volcanoes, magma transfer to the surface proceeds by subvertical ascent
from the mantle lithosphere through the oceanic crust and the volcanic edifice, possibly …

The mechanical conditions for a volcanic eruption to occur are conceptually simple: a
magma-driven fracture (normally a dyke) must be able to propagate from the source to the …

The 2007 caldera-forming eruption of Piton de la Fournaise (PdF) erupted the largest
volume of magma (210 Mm3) recorded at this volcano in at least three centuries. Major and …

Volcanic inflation and deflation often precede eruptions and can lead to seismic velocity
changes () in the subsurface. Recently, interferometry on the coda of ambient noise‐cross …

The largest effusive basaltic eruptions are associated with caldera collapse and are manifest
through quasi-periodic ground displacements and moderate-size earthquakes,–, but the …

Ocean wave activity excites seismic waves that propagate through the solid earth, known as
microseismic noise. Here we use a network of 57 ocean bottom seismometers (OBS) …

The dynamics of magmatic processes at large mafic ocean island volcanoes control the
likely locations (central caldera versus flanks) and timing of their eruptions. Crystals and …

Early detection of the onset of a caldera collapse can provide crucial information to
understand their formation and thus to minimize risks for the nearby population and visitors …

It is commonly accepted that effusive activity emplaces the main emitted magmatic volume in
basaltic shield volcanoes. At Piton de La Fournaise (La Réunion Island, France), eruptive …
