[HTML][HTML] Water in clinopyroxene from the 2021 Geldingadalir eruption of the Fagradalsfjall Fires, SW-Iceland
Water content plays a significant role in magma genesis, ascent rate, and, ultimately, in the
style and intensity of volcanic eruptions, due to its control on the density, viscosity and …

Magmatic controls on volcanic sulfur emissions at the Iceland hotspot
Outgassing of sulfur (as SO2) is one of the principal hazards posed by volcanic eruptions.
However, S emission potentials of most volcanoes globally are poorly constrained due to a …
