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

In the JGR-Solid Earth manuscript, we compare the modeled flow depths at all coral boulders locations on Anegada, British Virgin Islands. In this depository, we provide the main model datasets of the flow depth for tsunami and storm surge scenarios tested in the study.

## Description of the data and file structure: Tsunami modeling

### Model computational grid

The data file named \"anagada_10m.most\" is the model grid at the grid resolution of 10 m used to compute the inundation induced from all tested tsunami scenarios. This file is formatted for its use by the MOST model. It is a DEM data-formatted file contains ocean sounding, shoreline depth, and topographical elevation information for a grid of latitude and longitudes. The DEM data file format is a text file, written with a FORTRAN format of \"FORMATTED.\" Depth va...

本研究针对波多黎各海沟沿线的前殖民时期特大地震开展近场海啸（near-field tsunamis）与极端飓风模拟，以期为该事件提供进一步佐证。我们针对波多黎各海沟构建了25个理想海啸情景，其中包括19个逆冲断层（megathrust）震源与6个外隆起（outer rise）正断层震源，并通过模拟结果能否淹没约6个世纪前就位的漂砾（erratics）分布点位对模拟结果进行筛选。此外，我们还调研了15个五级飓风情景，并针对英属维尔京群岛阿内加达岛开展极端飓风情景下的风暴浪淹没高分辨率模拟。
模拟结果显示，该飓风情景会由拍岸浪（surf beat）引发类海啸波列，但多数珊瑚碎屑的分布范围超出了极端飓风模拟淹没的上限。筛选结果与已发表的海啸模拟结果整体吻合。由震级8.45的逆冲断层破裂或震级8.17的外隆起正断层破裂引发的海啸，在……处的流动水深可达1米及以上。

在《地球物理研究杂志：固体地球（JGR-Solid Earth）》的手稿中，我们对比了阿内加达岛所有珊瑚砾石点位的模拟流动水深。本存储库提供了本研究中测试的海啸与风暴潮情景的核心流动水深模型数据集。
