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.

本数据集收录了环太平洋俯冲带地震引发的海啸对罗斯冰架（Ross Sea Ice Shelf）影响的模型模拟结果，具体涵盖海啸水面高程的时间序列数据。本次模型模拟采用太平洋全域模拟提供的边界条件。模拟情景包含两类历史事件：一是2025年9月16日智利伊拉佩尔Mw 8.3级地震引发的海啸，二是2011年3月11日日本本州Mw 9.1级地震引发的海啸；此外还包含4组假想情景，分别由阿拉斯加、中美洲、克马德克（Kermadec）及新西兰-汤加俯冲带的Mw 8.6级地震生成。
