Data from 1564 earthquake/tsunami scenario simulations targeting the Nankai Trough subduction zone

Summary:

• Data from 1564 earthquake/tsunami scenario simulations targeting the Nankai Trough subduction zone
• Tsunami simulation solver: TUNAMI-N2
• Fault rupture model: Okada model (Okada, 1985)
• Each scenario data comprises 247 ASCII files storing the simulated wave sequences at synthetic gauges.
• Every single scenario is tagged as "JNan_X.X_YYY", where X.X indicates the magnitude and YYY is a serial number.
• Some synthetic gauges are in identical locations to actual ocean gauges (e.g., DONET2, NOWPHAS) near Shikoku, Japan.

Details of each file:

• data.tar.gz: A series of wave sequences (6-hour wave historical data, recorded every 5 seconds) at the 247 virtual gauges. Note that 52 GB of additional storage would be required to fully unzip this archive file with the following command.

  tar xzvf data.tar.gz

  The unzipped directory contains all scenario data as follows:

  Each directory contains 247 files named 'pntX_YY.asc'.

  In each ASCII file, the time (minute) elapsed from the fault rupture is aligned in the left column, and the wave displacements (meter) from the original sea level are in the right column.
