HighF v14.12 Data Comparison
From SCECpedia
In this page we show a comparison between seismograms generated by Hercules and AWP for some of the stations in the La Habra station list.

Background Information
Station Selection
We picked the following stations for this comparison:
- Short distance:
- FUL - 5.6 km
- BRE - 13.5 km
- DLA - 17.4 km
- Mid distance
- 24945 - 40.2 km
- GR2 - 40.5 km
- BHP - 40.5 km

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
