Model simulation data of tsunami propagation in the Pacific Ocean

The dataset includes model simulation results of the Pacific-wide propagation of tsunamis, specifically the time sequence of the water surface elevation of the tsunami, generated by circum-Pacific-Rim subduction zone earthquakes. 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 six scenarios generated by hypothetical Mw 8.6 earthquakes in the Alaska, Central America, South America, Kermadec, Kuil, and New Zealand-Tonga subduction zones, respectively. These simulation results have been used as boundary conditions to investigate tsunami impact in the West Antarctica ice shelves.
