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。第一部分针对苏门答腊-安达曼俯冲带（Sumatra-Andaman Subduction Zone）的地震断层机制（见表1）。该俯冲带共分为五个段落，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。断层尺寸由震级对应的总释放能量推导得出，后转换为破裂面积；破裂面积依据Wells与Coppersmith（1984）提出的缩放定律计算得到。第二部分为海啸数值模拟网格层（详见表2），该网格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。该网格层覆盖苏门答腊西海岸全域，共分为五级，即第1层至第5层：第1层网格分辨率最低，第5层网格尺寸最精细。
