Title: Dataset of tsunami simulation results for the Cascadia rupture scenarios Open Access Deposited

Attribute Value
Methodology
  • Tsunami simulation algorithm called MOST (Method of Splitting Tsunami) is applied to interpolated GEBCO bathymetry (General Bathymetric Chart of the Oceans;  https://www.gebco.net). Tsunami wave heights are calculated from sources included in this dataset in the form of fields of rupture slip and depth. Rupture scenarios are built using the Gamma locking model from Schmalzle et al (2014) [Schmalzle, G.M., McCaffrey, R. and Creager, K.C., 2014. Central Cascadia subduction zone creep. Geochemistry, Geophysics, Geosystems, 15(4), pp.1515-1532.]

####### DESCRIPTION:

1. simul.tar.gz

Compressed archive of

1-a. Fields of maximum tsunami amplitude in binary raster format (.grd).
These files are GMT-readable (Generic Mapping Tools; https://www.generic-mapping-tools.org).
1-b. Virtual gauge files. These are multiple column ASCII files.
Column belongs to each of the gauges and rows are time
series recorded at that station.

** Structure: the hierarchy is magnitude --> rupture scenario
Rupture scenarios for each magnitude (MX.Y) are stored in
stored in respective magnitude folder as RXXXX sub-directories
where XXXX is the index number for the scenario.

-------------------------------------------------------

2. slip.xyz

Three column (lon,lat,slip) ASCII file of the slip field. This is
the output of locking model (Schmalzle et al, 2014).

3. dep.xyz

Three column (lon,lat,depth) ASCII file of rupture depth. This is
the output of locking model (Schmalzle et al, 2014).

-------------------------------------------------------

4. slip.dyn.xyz

Three column (lon,lat,slip) ASCII file of the slip field. This is
the output of dynamic rupture model (Ramos et al, 2021).

5. dep.dyn.xyz

Three column (lon,lat,depth) ASCII file of rupture depth. This is
the output of dynamic rupture model (Ramos et al, 2021).

-------------------------------------------------------

6. def.smp.xyz

Three column (lon,lat,slip) ASCII file of the deformation field. This is
the a generic form of the model from Priest et al (2010).

-------------------------------------------------------

7. def.rand.xyz

Three column (lon,lat,slip) ASCII file of the deformation field. This is
the randomized ("noisy") version of the locking model (Schmalzle et al, 2014).

Notes:

The tsunami simulation algorithm MOST (Method of Splitting Tsunami;
Titov et al, 2016) is available via NOAA (https://nctr.pmel.noaa.gov/model.html).

Surface deformation fields for ruptures can be calculated from the slip field
using earthquake scaling laws (e.g., Geller, 1976) and deformation algorithms
(e.g., Mansinha & Smylie, 1971).
