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）的地震断层机制相关数据（见表1）。该俯冲带共分为5个分段，分别为亚齐-安达曼（Aceh-Andaman）、尼亚斯-锡默卢（Nias-Simeulue）、西比路-明打威（Siberut-Mentawai）、恩加诺（Enggano）以及巽他海峡（Sunda Strait）。断层的尺寸基于震级释放的总能量确定，随后转换为破裂面积，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）计算得出。第二部分为海啸数值模拟网格层相关数据（见表2）。该数据集适配使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，网格层覆盖苏门答腊岛西海岸全域。该网格层共分为5个层级，即第1层至第5层，其中第1层的网格最为粗糙，第5层的网格尺寸最精细。
