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.
