Graves Hanging Wall Study
Study Specifications
This Wiki page describes the simulations that will be performed on the Broadband Platform to investigate footwall / hanging wall and directivity effects for NGA-W2. This simulation is expected to generate 205,776 3-component seismograms. Robert Graves has written a specification for a set of footwall and hanging wall simulation in this document HangingWall Specfiications 2011.
Setting Up Study Inputs and Outputs
Untar the Graves input data set:
$ tar xvf graves_hwfw_inputs.tar
Untar the Graves reference output data set:
$ tar xvf graves_hwfw_outputs.tar
Generate the three source description variations:
$ cd BBP-Runs001 $ ./gen_source_input.csh
Running Study with Broadband 11.2.2
Set ROOT_PATH (line 16) in ./BBP-Runs001/run_bbp-parallel.csh to the root directory where you untarred the input and output data sets. The line you want to edit is:
set ROOT_PATH = /home/scec-02/USER/HwFw
Ensure your BBP environment is setup according to the Broadband User Guide. Create and run the simulation workflows with this script:
$ cd BBP-Runs001 $ ./run_bbp-parallel.csh
On a dual core system, this script will require several weeks to run.

Computational Estimates for Hanging Wall Problem
The Footwall/Hanging wall problem has been defined as a set of (1) ruptures, (2) variations for each rupture, (3) station list for each rupture, and (4) code-bases used. A useful metric is the total number of 3 component seismograms required to completed the problem.
36 Code base combinations in Broadband v11.2.1 Stations in Station List by rupture ------------------- Mw6.0: 105 Mw6.5: 117 Mw7.0: 163 Mw7.5: 175 Rupture Variation by magnitude ------------------- Mw6.0: 9 Mw6.5: 9 Mw7.0: 11 Mw7.5: 11 Seismograms per run (stations * variations): -------------------------------------------- Mw6.0: 105 * 9 = 945 Mw6.5: 117 * 9 = 1053 Mw7.0: 163 * 11 = 1793 Mw7.5: 175 * 11 = 1925 ------------------ Total: 5716 seismograms per problem Total Seismograms = 36*5716 = 205,776 Runtime Estimates: (6.0 40 mins, 6.5 2 hrs, 7.0 8 hrs, 7.5 34 hrs) Mw6.0: (9*36) runs *40 mins = 216 hrs Mw6.5: (9*36) runs *2 hrs = 648 hrs Mw7.0: (11*36) runs *8 hrs = 3168 hrs Mw7.5: (11*36) runs *34 hrs = 13464 hrs ------------------------------------------- Total runtime (1 core): 729 Days
