Mantle-sourced magmas erupted at hotspot volcanoes can provide clues to the sulphur cycle over geological timescales. In this work, sulphur isotopes were analysed in crystal-hosted inclusions entrapped at depth, and reveal the presence of post-Archae

Cumbre Vieja volcano, on La Palma, Canary Islands, Spain, is an excellent natural laboratory for exploring igneous processes at the individual eruption scale (e.g. eruption precursors) and at the larger volcanic-magmatic-system scale (e.g. repose per

The 2021 eruption of Cumbre Vieja volcano (La Palma, Canary Islands) produced sustained Strombolian to violent Strombolian explosive activity, resulting in widespread tephra fall deposits in addition to lava flows. Frequent sampling of rapidly quench

Recent studies investigating magmatic volatile contents indicate widespread enrichment of carbon, sulfur, and halogens in ocean island basalts (OIBs). At El Hierro in the Western Canary Islands, magmas with exceptionally high CO2 and S contents have

Highlights • Regardless of eruptive style, Masaya magmas are compositionally similar. • Volatile contents are higher in Plinian samples, but low compared to CAVA magmas. • All Masaya magmas undergo extensive pre-eruptive degassing at low pressu
