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.

Simulation Results - 5 January 2016

Same data as 14 December 2015, but updated RWG data for 3 closest stations.

Simulation Results - 15 December 2015

Same data as 14 December 2015, but adding observation data.

Simulation Results - 14 December 2015

Same data from 7 December 2015, updated RWG data for the three closest stations only.

Simulation Results - 7 December 2015

Same data from 20 November 2015, updated processing as follows:

  • Filter at 10Hz back and forward, 4 poles, using filtfilt
  • Interpolate 1D linear to AWP's 0.025 dt
  • Trim longest data sets to match the shortest one
  • Taper at the last 2 seconds: hanning with 161 points, then take 81 last values and apply this to last 81 points of each time series
  • Pad last 5 seconds with zeroes
  • Filter at 4Hz 4 poles back and forward with filtfilt
  • Plot time series and FFT using 1.25 filter frequency
  • Repeat last 2 steps with filter frequency set to 0.5, 1, 2, and 3 Hz

Simulation Results - 20 November 2015

AWP and Hercules data from 5 November, but updated RWG results to correct issue in the mesh conversion code. Added results for far-distance stations as RWG data now goes to 100s.

Simulation Results - 05 November 2015

Results from RWG, updated SDSU results by increasing the number of points in the sponge zones for the Cerjan boundary conditions from 20 points (previous runs) to 90 points.

Simulation Results - 14 October 2015

La Habra earthquake with Hercules at 14 ppw, 4Hz, Min Vs = 500m/s, CVM-S4.26, 3D, with Q

Simulation Results - 2 October 2015

La Habra earthquake with constant Q based on CVM-S4.26 w Min Vs 500m/s. Hercules results down with 10ppw (same as 28 September) but reference frequency is 0.0 Hz (it helps to decrease the phase dispersion).

Simulation Results - 28 September 2015

La Habra earthquake with constant Q based on CVM-S4.26 w Min Vs 500m/s. Hercules results down with 10ppw

Simulation Results - 31 August 2015

La Habra-scale earthquake w/ constant Q in 1D Velocity. Adding Hercules results to previous AWP-ODC and RWG results from August 13. Filtered plots were generated using SAC's "lowpass" command, with 4 poles and 4Hz as the corner frequency.

Simulation Results - 18 August 2015

Updated SDSU results, comparing La Habra synthetics for AWP, with Q(f) in the 1D model. Here, Q(f)=Q0 f^0.8, where Q0 are the values that we have been using for the constant-Q case. Filtered plots were generated using SAC's "lowpass" command, with 4 poles and 4Hz as the corner frequency.

Simulation Results - 13 August 2015

La Habra-scale earthquake w/ constant Q in 1D Velocity. Updated results for AWP-ODC and RWG. Filtered plots were generated using SAC's "lowpass" command, with 4 poles and 4Hz as the corner frequency.

Simulation Results - 3 August 2015

La Habra-scale earthquake w/ constant Q in 1D Velocity

Simulation Results - 20 July 2015 - Half Space

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:

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 - 29 June 2015

Results from AWP, Hercules, RWG, and Hercules-Refined. The Hercules refined results were done with 10 p/w without filtering the source, lossless, refined mesh for upper ~60 meters.

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.

Results without attenuation for AWP, Hercules, and RWG.

Simulation Results - 16 June 2015

Simulation Results - May 18th 2015

Results without attenuation for both AWP and Hercules. Filtered plots were generated using SAC's "lowpass" command, with 4 poles and the corresponding corner frequency.

Data from the two methods are available here:

Simulation Results - May 13th 2015

AWP results are the same as in May 11th, Hercules results were updated with Reference Frequency = 0.5Hz, source without filtering.

Data from the two methods are available here:

Simulation Results - May 11th 2015

Hercules data uses Reference Frequency of 1Hz.

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
