A glacierocean interaction model for tsunami genesis due to iceberg calving
Glaciers calving icebergs into the ocean significantly contribute to sea-level rise and can trigger tsunamis, posing severe hazards for coastal regions. Computational modeling of such multiphase processes is a great challenge involving complex solidfluid interactions. Here, a new continuum damage Ma...
