Glacier calving, the process of icebergs breaking off from glaciers and falling into the ocean, significantly contributes to sea-level rise and can trigger tsunamis. This paper presents a new continuum damage Material Point Method (MPM) model to simulate the complex interaction between glacier fracture and the subsequent generation of tsunami-like waves. The model accurately reproduces features of tsunamis observed in laboratory experiments and field measurements at Eqip Sermia, Greenland. This hybrid approach improves the modeling of solid-fluid interactions, offering potential for refining calving laws in large-scale earth-system models and enhancing hazard assessments in coastal regions.
