Model data of tsunami and storm surge scenarios for Anegada, British Virgin Islands

We modeled near-field tsunamis and extreme hurricans to provide further
evidence for a great precolonial earthquake along the Puerto Rico Trench.
25 hypothetical tsunami scenarios, 19 megathrust sources and 6 normal
faulting on the outer rise, of the Puerto Rico Trench were modeled and the
model results were screened by their success in flooding the mapped sites
of these erratics, which were amplaced some six centuries ago. We also
investigated 15 hurricane scenarios of category 5, and modeled the most
extreme hurricane scenario for high-resolution simulation of storm wave
inundation at Anegada. Our models showed the hurricane scenario produced
tsunami0like bores from surf beat, but many coral clasts lie beyong the
reach of simulated flooding from the extreme hurricane. The screening
results broadly agree with those from previously published tsunami
simulations. The tsunamis from either a M 8.45 megathrust rupture or a M
8.17 outer-rise normal fault produce flow depths of 1 m or more at al the
clasts sites. This depository provides the datasets of model grid
and simulation results for tsunami and hurricane scenarios tested in the
JGR-Solid Earth manuscript 2023JB028387. These datasets, with their
details provided in the README file, include the model grids and hurricane
tracks used as input for model simulations and model output data files
produced by those model simulations of tsunamis and hurricanes. They are
the model data used to produce most of the main and supplement figures
shown in the manuscript.

本研究针对波多黎各海沟（Puerto Rico Trench）前殖民时期的一次特大地震展开模拟，以期获取更多实证证据。我们共构建了25个假想海啸情景，其中包含19个巨型逆冲震源（megathrust source）与6个外隆起带（outer rise）正断层震源，所有情景均围绕波多黎各海沟开展。随后通过模型模拟的洪水能否覆盖这些漂砾（erratics）的已测绘位点——这些漂砾距今已有约6个世纪的留存历史——来筛选模型结果。
此外，我们还研究了15个五级飓风（category 5 hurricane）情景，并针对阿内加达岛（Anegada）的风暴潮淹没场景开展了极端飓风情景的高分辨率模拟。
模拟结果显示，该极端飓风情景下会因海浪拍击振荡产生类海啸涌浪，但多数珊瑚碎屑的分布范围远超此次极端飓风模拟的淹没上限。
此次模型筛选结果与此前已发表的海啸模拟结论基本一致。
无论是8.45级巨型逆冲断层破裂引发的海啸，还是8.17级外隆起带正断层破裂引发的海啸，在所有碎屑位点处的水流深度均可达到1米及以上。
本数据存储库为发表于《地球物理研究杂志-固体地球（JGR-Solid Earth）》、稿件编号为2023JB028387的研究提供了海啸与飓风情景测试所需的模型网格与模拟结果数据集。
本数据集的详细说明已收录于自述文件（README）中，包含模型模拟所需的输入数据（模型网格与飓风路径），以及由海啸和飓风模拟生成的模型输出数据文件。
这些模型数据用于生成该稿件中绝大多数主图与补充图。
