Members of the UGMS committee requested a comparison of probabilistic RTGM spectra for the GMPEs with and without UCERF2 background seismicity included. As CyberShake does not currently consider background seismicity, this to test the assumption that the contribution from background seismicity is negligable in the Los Angeles region. These calculations use the average of the 2014 NGAWest2 GMPEs, excluding Idriss.

Study Sites

MCER Sites 2014.png

We are calculating MCER results for 14 sites, available in a KML file Image to the right shows the location of the MCER 2014 study sites. These sites can be plotted using the following KML file:

Near surface information about these sites includes Vs30, Z1.0, Z2.5 Values. These values are used in GMPE calculations for these sites. Site names, locations, and near surface values are listed in the following file.

Results

Plots for each of the 14 sites are available in the following table.

Probabilistic MCER Results

UGMS map.jpg

CyberShake probabilistic MCER results for the 14 sites. This also contains comparable RotD100 results for the 2008 and 2014 NGAs.

This zip file contains pseudo spectral velocity plots for the probabilistic results.

Metadata for these results include:

  • CyberShake Model: Study 14.2
  • Velocity Model: CVM-S4.26
  • Earthquake Rupture Forecast: UCERF2
  • Rupture Generator: GP 2010
  • Background Seismicity: None
  • RotD100 Software: Modified BBP RotD50
  • GMPE 2008 GMRotI50 to RotD100 conversion factors: See spreadsheet
  • GMPE 2014 RotD50 to RotD100 conversion factors: See spreadsheet

Disaggregation Plots

We disaggregated the CyberShake and NGA hazard curves at 3 seconds and plotted the top 10 contributors for each site. These plots are available here: Disaggregation Plots

Background Seismicity Plots

To determine the impact of background seismicity, we calculated the contributions of on-fault and background seismicity to the NGA hazard curves. These plots are available here: Background Seismicity Contribution Plots


Deterministic MCER Results

Zoomed map.png

CyberShake deterministic MCER results for the 14 sites, along with comparable results for the 2008 and 2014 NGA models.

This zip file contains pseudo spectral velocity plots for the deterministic results.

Metadata for these results include:

  • CyberShake Model: Study 14.2
  • Velocity Model: CVM-S4.26
  • Earthquake Rupture Forecast: UCERF2
  • Rupture Generator: GP 2010
  • Background Seismicity: None
  • RotD100 Software: Modified BBP RotD50
  • GMPE 2008 GMRotI50 to RotD100 conversion factors: See probabilistic spreadsheet
  • GMPE 2014 RotD50 to RotD100 conversion factors: See probabilistic spreadsheet

Combined MCER Plots

From the probabilistic and deterministic results, we have produced combined MCER plots of two types, both plotting PSV at periods from 1-10 sec, using the probabilistic and deterministic results previously calculated for the 14 sites identified by the Utilization Committee.

Type A contains 5 curves for each site and are available in a zip file here: All combined plots (~400KB zip file containing PDF, PNG, and TXT files)

  1. average of the probabilistic NGAs (2014) without Idriss. This was obtained by averaging the 4 NGA hazard curves, then convolving with the fragility function.
  2. average of the deterministic NGAs (2014) without Idriss
  3. probabilistic MCER for Cybershake
  4. deterministic Cybershake
  5. ASCE 7-10 Det Lower Limit

Type B contains 3 curves for each site and are available in a zip file here: MCER combined plots (~300KB zip file containing PDF, PNG, and TXT files)

  1. CyberShake: lower of probabilistic MCER and (higher of deterministic and ASCE deterministic lower limit). For CyberShake, the probabilistic is always lower than the deterministic.
  2. NGA (2014): lower of probabilistic MCER and (higher of deterministic and ASCE deterministic lower limit).
  3. ASCE 7-10 Ch 11.4

GMPE Background Seismicity Sensitivity

Members of the UGMS committee requested a comparison of probabilistic RTGM spectra for the GMPEs with and without UCERF2 background seismicity included. As CyberShake does not currently consider background seismicity, this to test the assumption that the contribution from background seismicity is negligable in the Los Angeles region. These calculations use the average of the 2014 NGAWest2 GMPEs, excluding Idriss.

The result for the LADT site is shown below.
