######## RESEARCH OVERVIEW ########
This study used three-dimensional, dynamic earthquake simulations to investigate how stress
and friction levels on the Cascadia megathrust fault influence the final earthquake size
and coastal subsidence patterns from the 1700 A.D. earthquake.
######### METHODS ########
The simulations are carried out using the open-source software, SeisSol.
The 3-D finite element mesh (FEM) for the Cascadia and surrounding topography/bathyemtry was
created using Simmetrix.
Results may be viewed with Paraview (.xdmf files) or if in ascii text form (.txt) with python
or similar scientific scripting language.
Static stress-drop is calculated from the coupling models using Poly3D, which is freely available.
No data was collected during this study. Where appropriate, readers may refer to Table 1
in Wang, P-L et al., (2013) for the tabulated subsidence values.
######## FILE INVENTORY ########
There are eight main figure directories in Paper_Figures/ for the submitted manuscript (subject to change before peer-review process is done).
Six additional directories (e.g., S#/) contain data and scripts for plotting suppplemental information.
Thus, fourteen figure directories are included with this dataset.
There are two directories that include a collection of MATLAB and python scripts for pre- or post-
processing the simulation data
The directory MESH/ contains the 3-D finite element mesh used to run simulations in this paper
A directory containing example simulation input data files (.yaml), the FEMs, and example output data will be made available.
######## USE AND ACCESS ########
Required Software: MATLAB, Python (>3.3), Poly3D (https://github.com/stgl/poly3d),
SeisSol (downloadable/clone from https://github.com/SeisSol/SeisSol.git)
SeisSol requires several dependenceis and a comprehensive set of directions for installation may be found at:
https://seissol.readthedocs.io/en/latest/index.html
Computational Requirements: Simulations for this paper were conducted on the Great Lakes parallel computing
cluster at the University of Michigan (https://arc.umich.edu/greatlakes/)
or on SUPERMUC-NG, a supercomputing cluster within theLeibniz Supercomputing Centre, Munich (Germany).
