Carbonate-capped seamount subduction accelerates CO 2 -rich arc magma ascent

Nature Communications, Published online: 25 May 2026; doi:10.1038/s41467-026-71536-3 CO2-rich magmas beneath Pagan Volcano are stored near Moho depths and ascend to the surface within weeks to months. These findings link deep, rapid magma ascent to carbonate capped seamount subduction and highlight the role of recycled carbon in arc volcanism.
