Investigations of three of the most active caldera volcanoes in the Aleutians (Okmok, Westdahl, and Veniaminof) reveal stark variations in magma processes despite similarities in structure and composition. To better understand these differences, we used computer models that simulate how magma behaves underground. This work shows why forecasting volcanic eruptions is so difficult. It also highlights the need to integrate models with real-world data to cope with the unpredictable behavior of complex volcanic systemsand better mitigate risks.
