Updated results from all groups. AWP-ODC results shifted right by 0.025s, as instructed by KO. Hercules team provided two sets of results, with 10 and 20 points per wavelength. These are plotted separately as two sets:
- Short Distance (10 ppw)
- FUL - 040 component (Combined) (FFT), 130 component (Combined) (FFT), VER component (Combined) (FFT)
- BRE - 040 component (Combined) (FFT), 130 component (Combined) (FFT), VER component (Combined) (FFT)

- DLA - 040 component (Combined) (FFT), 130 component (Combined) (FFT), VER component (Combined) (FFT)
Simulation Results - 20 July 2015
Updated results:
- AWP/ODC: With corrected station positions and a fix for a small time delay. Please note that the orientations are relative to the rotated domain; i.e. '000' means N40dE, and 090 N130dE
- RWG: Short, mid and far sites computed using emod3d. This is the same as what I sent earlier (for eight of the 9 sites), except that this package includes the response for station CI_Q0049.
- Hercules: New set of results obtained with Hercules for La Habra with the 1D profile. This set was obtained in a reduced domain and only for the near and mid-range stations, using 20 points per wavelength. I did some plots myself and in my opinion this is the best we are ever going to do, and I think it is pretty good. I still want to see the comparisons done by you, independently. I recommend you do the following, plot this against AWP and Graves results, without filtering. And then plot the same, filtering at 4 Hz. No need to do other lower filters as you did before, 4 Hz will be enough.

Simulation Results - 25 June 2015
Here's an update on the preliminary modeling I've done for La Habra. I took the 1D velocity model and ran an FK calculation for the 3 nearby sites. I also convolved the FK response with the same slip-rate function used for the FD calculation. The attached plots compare the FD and FK waveforms for these 3 sites. I did not apply any additional filtering to the waveforms, so they should contain frequencies up to 5 Hz (based on my understanding of the freq. content of the slip-rate function). The agreement between FD and FK is very good. This is the level of agreement that I think we can obtain as long as the model inputs are defined consistently. (Note: the late arriving blips in the FD are boundary reflections.)
On this later point, I used a velocity structure for the FK calculation that is consistent with the model representation used for my FD implementation. This means that the layer boundaries are at depths of z=0.01 km + J*0.02 km for some integer J. In other words, the shallowest layer has its bottom at 10 meters depth, and then all subsequent layers are at depths of 30, 50, 70, ... meters. I've attached a couple of plots (different resolutions) showing Vp (heavy line), Vs (thin line) and Den (dashed line) for the upper portion of the model I'm using. While this representation of the 1D structure is valid, I'm not sure if this structure is strictly the same as that "seen" by AWP and Hercules due to the way they discretize the medium.

You can see the above stations on a map by downloading the kml file and opening with Google Earth.
Hercules Data Files
The Hercules results are located on Blue Waters at ‘/u/sciteam/khoshnev/scratch/N_Lahabra_sim_4Hz/ ‘. The stations are in '../outputfiles/stations/' folder. X and Y components are according to the simulation domain (rotation angle 39.9). For Z component simply multiply it by -1 to get the same positive direction with data. There are 356 stations, which are same as the SCEC wiki page but are ordered according to the epicentral distance (smaller to larger, please see the station list below).
Hercules File format
Each file has 10 columns as follows:
- C1 : Time steps
- C2,C3,C4 : Displacement ( Directions : | , --- , . ) (m)
- C5,C6,C7 : Velocity ( Directions : | , --- , . )(m/s)
- C8,C9,C10 : Acceleration ( Directions : | , --- , . )(m/s2)

Hercules Station Mapping
Since the Hercules station list was sorted by epicentral distance, we need to map the desired station names into the Hercules stations.
- Short distance
- FUL --> Hercules station.5
- BRE --> Hercules station.23
- DLA --> Hercules station.41
- Mid distance
- 24945 --> Hercules station.222
- GR2 --> Hercules station.223
- BHP --> Hercules station.224
- Large distance
- Q0049 --> Hercules station.334
- AGO --> Hercules station.335
- PTD --> Hercules station.336
AWP Data Files
The AWP results are located at '/u/sciteam/wsavran/scratch/la_habra/1d’ on Blue Waters. You will find 3 files named seis_[x,y,z]0075000, which correspond to the x, y, and z components respectively. These components are aligned with the simulation domain, so they will need to be rotated into the E-W and N-S directions if desired.
The AWP files are 4-byte little-endian floating point numbers stored fast time, then station. The time-series are 3000 points long with a dt of 0.025s resulting in 75.0 seconds of simulation time. We have extracted seismograms at the 356 stations listed in the order they are present on the SCEC wiki page:
The files labeled seis_[x,y,z]0075000 are the aggregated seismograms, meaning they are already extracted from the simulation output. They are 4 byte little-endian floating point numbers with fast-time. There are 356 stations with 3,000 time points each. The ordering of the stations is the same as the station list provided at the SCEC High-F wiki page. They are the [x,y,z] components of ground motion aligned with the simulation domain.
AWP File Format
The 3 files above were processed by William, and split into 356 separate files, one for each station. These files were names <station_id>-AWP-ODC.dat, where station_id is the id listed for each station in the SCEC station wiki page linked above. The processed files are velocity seismograms in ASCII format, using the following format:
- C1 (Time)
- C2 (X_Velocity m/s)
- C3 (Y_Velocity m/s)
- C4 (Z_Velocity m/s)
They are in a raw form, meaning they have not been rotated or filtered as this should be done carefully to be the exact same between both simulations.
Generating Comparison Plots
In order to generate comparison plots using SAC, the following steps are needed.
Processing AWP files
AWP files are already in a 4-column timestamp, data, data, data format, but need to be converted so that X and Y components match the order in the BBP files. We can use the awp2bbp tool for that:
- awp2bbp.py CI_FUL-AWP-ODC.dat CI_FUL-AWP-ODC.bbp
- awp2bbp.py CI_BRE-AWP-ODC.dat CI_BRE-AWP-ODC.bbp
- awp2bbp.py CI_DLA-AWP-ODC.dat CI_DLA-AWP-ODC.bbp
Then, we can use the bbp2sac utility to convert these files into 3 sac files (X/Y/Z), using the following commands:
- bbp2sac.py CI_FUL-AWP-ODC.bbp
- bbp2sac.py CI_DLA-AWP-ODC.bbp
- bbp2sac.py CI_BRE-AWP-ODC.bbp
Processing Hercules files
Hercules files first need to be converted into a 4-colum timestamp, data, data, data format. We use a new "hercules2bbp.py" script that reads each line and selects the columns containing the velocity data:
- hercules2bbp.py station.5 CI_FUL-Hercules-vel.bbp
- hercules2bbp.py station.23 CI_BRE-Hercules-vel.bbp
- hercules2bbp.py station.41 CI_DLA-Hercules-vel.bbp
After this step is completed, we can use the bbp2sac.py tool to convert the bbp files into sac format:
- bbp2sac.py CI_FUL-Hercules-vel.bbp
- bbp2sac.py CI_BRE-Hercules-vel.bbp
- bbp2sac.py CI_DLA-Hercules-vel.bbp
Plotting using SAC
$ sac SAC> r ./CI_FUL-*.000.sac SAC> xlim 0 8 SAC> ylim -0.25 0.30 SAC> xlabel "Time (s)" SAC> ylabel "m/s" SAC> color r SAC> grid on SAC> title "STATION FUL - Y component" SAC> p1 SAC> saveimg FUL-Y.pdf SAC> r ./CI_FUL-*.090.sac SAC> title "STATION FUL - X component" SAC> p1 SAC> saveimg FUL-X.pdf SAC> r ./CI_FUL-*.ver.sac SAC> title "STATION FUL - Z component" SAC> p1 SAC> saveimg FUL-Z.pdf
Plotting FFT using SAC
$ sac SAC> r ./CI_FUL-*.000.sac SAC> color r increment list red blue SAC> xlim 0.1 25 SAC> xlabel "Frequency" SAC> ylabel "FAS" SAC> loglog SAC> fft SAC> title "Station FUL - Y component" SAC> p2 SAC> saveimg FUL-Y-FFT.pdf SAC> r ./CI_FUL-*.090.sac SAC> fft SAC> title "Station FUL - X component" SAC> p2 SAC> saveimg FUL-X-FFT.pdf SAC> r ./CI_FUL-*.ver.sac SAC> fft SAC> title "Station FUL - Z component" SAC> p2 SAC> saveimg FUL-Z-FFT.pdf
