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``
