We describe new observations from three Chilean volcanoes that help us to better understand what happens when a lava flow is erupted from an ice covered volcano. We have found evidence that many such eruptions probably produce meltwater floods that travel down through pre-existing tunnels/channels in the ice. Our new findings are similar to what others have seen during historic eruptions at other volcanoes, and so our observations show that these processes have been happening at Chilean volcanoes for many years, and will likely continue into the future as long as there are ice-covered volcanoes in Chile.
