Determining the rate and amount of meltwater produced when volcanic materials interact with glaciers is important for modeling massive glacial flooding. We conducted laboratory experiments to study the effects of hot volcanic material interacting with ice, and ice mixed with sediments. We used water-ice blocks with varying amounts and sizes of sediment frozen within them, and placed hot rock blocks or small amounts of liquid lava on top of or beneath the ice. We measured the temperatures of the rock, lava, and meltwater, along with the amount of meltwater produced, over time. Meltwater volume and rock temperature were correlated, with large amounts of meltwater produced at the beginning when the rock was hottest and first contacted the ice. Sediments within the ice provided an insulating effect, which lowered the cooling rate of the rock and the amount of meltwater produced.
