Output Formats¶

USGS Slab Models¶

Slab models are stored as folders containing relevant slab geometry information, and can be found in src/output/. Each model contains the following files with example file names for a Cascadia slab surface model made with the 0724 database:

Depth Grid File¶

An hdf5 file containing values representing the depth (in km) of the slab surface (or center if specified). This file is used for most slab geometry analysis.

Example:

cas_slab2_surf_dep_07-24.grd

Dip Grid File¶

An hdf5 file containing values representing the dip (in degrees) of the slab surface (or center if specified).

Example:

cas_slab2_surf_dip_07-24.grd

Strike Grid File¶

An hdf5 file containing values representing the strike (in degrees) of the slab surface (or center if specified).

Example:

cas_slab2_surf_str_07-24.grd

Thickness Grid File¶

An hdf5 file containing values representing the thickness (in km) of the slab.

Example:

cas_slab2_surf_thk_07-24.grd

Uncertainty Grid File¶

An hdf5 file containing values representing the depth uncertainty (in km) of the slab model.

Example:

cas_slab2_surf_unc_07-24.grd

Clipping File¶

A CSV file containing the longitude and latitude of points used to define the clipping polygon for slab boundaries.

Example:

cas_slab2_surf_clp_07-24.csv

Supplementary File¶

Only used for overturned slab models, a CSV file which defines the overlapping portion of the slab model.

Example for Solomon Islands Model:

sol_slab2_surf_sup_07-24.csv

Parameter File¶

A CSV file containing parameters used when generating the model if changed from the default values.

Example:

cas_slab2_surf_par_07-24.csv

L-Curve File¶

If L-Curve (lcv) analysis is performed on the model, a CSV file containing analysis outputs and figure will be saved to the model.

Example:

data file cas_slab2_lcv_07-24.csv
figure cas_slab2_lcv_07-24.png

Seismogenic Zone Thickness File¶

If Seismogenic Zone Thickness (szt) analysis is performed on the model, a CSV file containing analysis outputs will be saved to the model.

Example:

data file cas_slab2_szt_07-24.csv
figure cas_slab2_szt_07-24.png

Maps¶

If map.py or xsec.py scripts are run for a model, resulting figures saved as PDF files will be saved to the model.

Example:

cas_07-24_maps and cas_07-24_xsec
