Model simulations of tsunami propagation from Circum-Pacific Subduction Zone to West Antarctic Ice Shelves (Ross Sea)

The dataset includes model simulation results of the tsunami impact on the Ross Sea Ice Shelf, specifically the time sequence of the water surface elevation of the tsunami, generated by circum-Pacific-Rim subduction zone earthquakes. The model simulations utilized the boundary conditions provided by the Pacific-wide simulations. The simulation scenarios include two historical events, the September 16, 2025 tsunami generated by the Mw 8.3 Illapel, Chile earthquake and the March 11, 2011 tsunami generated by the Mw 9.1 Honshu, Japan earthquake. Also included are four scenarios generated by hypothetical Mw 8.6 earthquakes in the Alaska, Central America, Kermadec, and New Zealand-Tonga subduction zones, respectively.
