This is a summary of: Wu, J. et al. Low sulfur emissions from 2022 Hunga eruption due to seawater–magma interactions. Nat. Geosci. https://doi.org/10.1038/s41561-025-01691-7 (2025). Calculation of the sulfur and water budgets released from magma during the 2022 eruption of Hunga volcano — the largest submarine eruption recorded — shows that of 18.8 Tg of sulfur dioxide released, <7% entered the atmosphere. The remaining sulfur dioxide dissolved in the ocean during explosive magma fragmentation at 400–1,000 m below sea level.
