Volcanic eruptions occurring under glaciers melt cavities in the overlying ice, and this meltwater may drain out in a large, sudden flood known as a jökulhlaup. Observations show that ice melts rapidly in liquid‐filled subglacial cavities when these eruptions occur, but until now scientists have not had a quantitative description of the heat transfer processes involved.
