Description

Summary: Data of 2342 hypothetical Nankai Trough events Tsunami propagation is simulated by the GeoClaw software (Clawpack Development Team, 2021). Earthquake realizations generated by the Mudpy software (Melgar, 2020). Data composition is as follows:nankai_data├── quakes│ ├── dtopofiles│ │ ├── nankai_xy_zzzzzz.dtt3│ │ ├── ...│ ├── png│ │ ├── nankai_xy_zzzzzz_slip_dtopo.png│ │ ├── ...│ └── ruptures│ ├── nankai_xy_zzzzzz.log│ ├── nankai_xy_zzzzzz.rupt│ ├── ...├── waves│ ├── nankai_xy_zzzzzz.csv│ ├── ...├── gauge_loc.csv└── wave_seq.npy Details of each file: Unzipping `nankai_data.tar.gz` creates two directories and two file: `quakes/`, `waves/`, `gauge_loc.csv` and `wave_seq.npy`.Note that 8 GB of additional storage is required. quakes/ Earthquake data of 2342 scenarios. quakes/dtopofiles/nankai_xy_zzzzzz.dtt3Seafloor deformation of each scenarioMw: x.y, ID: zzzzzz quakes/ruptures/nankai_xy_zzzzzz.rupt stores the rupture for each scenario.nankai_xy_zzzzzz.log has information about the rupture. quakes/png/nankai_xy_zzzzzz_slip_dtopo.pngThe slip distribution and seafloor deformation due to fault rupture are visualized in PNG format. waves/ 2342 .csv files contain time series data of simulated tsunami wave heightsThe left column has the time (minute) elapsed from the fault ruptureThe following columns have the wave sequences recorded at each gaugeEach file has 2160 rows corresponding to the simulation time steps, 3 [hr] x 3600 [sec/hr] / 5[sec] = 2160. gauge_loc_all.csv The locations of 62 synthetic gaugesGauge IDs are in the left column named ID.The gauge locations are in Longitude and Latitude columns.Some of the synthetic gauges are set by referring to the locations of existing gauges, as shown in the Instruments column. wave_seq.npy Data matrix containing the wave sequences.Loading this binary data by numpy.load('wave_seq.npy')gives a 2342 x 62 x 2160-shaped 3d array.
