Seismic Fault Mechanisms and Numerical Simulation Layers for Tsunami Simulations along West Coasts of Sumatra, Indonesia

These datasets consist of two parts. The first part is for seismic fault mechanisms along Sumatra-Andaman Subduction Zone (Table 1). There are five segments along the subduction zone, i.e. Aceh-Andaman, Nias-Simeulue, Siberut-Mentawai, Enggano, and Sunda Strait. The dimension of the faults were based on total energy released by the magnitudes and later were transformed into rupture area. The rupture area were calculated based on Scaling Laws of Wells and Coppersmith (1984).

The second part is for the tsunami numerical simulation layers (see Table 2). These best fit to tsunami numerical simulations using Cornell Multigrid Coupled Tsunami Model (COMCOT). The layers cover all areas along the west coasts of Sumatra. There are five levels of the layers, namely Layer 1 until Layer 5. Layer 1 has the coarsest grids and Layer 5 has the finest grid size.

本数据集包含两个部分。第一部分为苏门答腊-安达曼俯冲带（Sumatra-Andaman Subduction Zone）的地震断层机制研究（见表1）。该俯冲带共分为五个分段，分别为亚齐-安达曼段、尼亚斯-锡默卢段、西布鲁特-明打威段、恩加诺段以及巽他海峡段。断层的尺寸基于震级对应的总释放能量计算得出，后转换为破裂面积，破裂面积则根据威尔斯与库珀史密斯（Wells and Coppersmith）1984年提出的缩放律（Scaling Laws）计算得到。

第二部分为海啸数值模拟图层（见表2）。该系列图层适配采用康奈尔多重网格耦合海啸模型（Cornell Multigrid Coupled Tsunami Model, COMCOT）开展的海啸数值模拟，覆盖苏门答腊岛西海岸全域。该系列图层共分为五个等级，即图层1至图层5，其中图层1的网格精度最低，图层5的网格尺寸最精细。
