Three Dimensional Wave Propagation
in Seismic Fault Zone Models

Errata:
Shown in the seismogram plots and the snapshot plots is always the Y-Component, not the X-Component!

 
  • Title
  • Testing against Analytical Solutions (Plot is identical to my poster at the AGU 99)
  • Geometry (all models have this geometry and source in common)
  • Basic Model (Basic fault model with source at fault's border - comparison to homogeneous model)
  • Snapshots for Basic Model (1) (Snapshots of Y-component of wave propagation in the plane perpendicular to the fault - source is located at the faults'border)
  • Snapshots for Basic Model (2) (Snapshots continued)
  • Basic Model - Source 300m outside  (Like Basic Model, but with source shifted outside the fault. Much less trapped waves occur.)
  • Basic Model - Source 150m outside (Like Basic Model, but with source shifted 150m outside the fault. Waveforms look similar to the Basic Model)
  • Basic Model - Source centered in Fault (Like Basic Model, but with source shifted to the center of the fault. Waveforms look similar to the Basic Model)
  • Bottleneck Model (Like Basic Model but with narrow domain, dispersion of the trapped waves can be seen.)
  • V-Shaped Model (Like Basic Model, but with increasing fault with towards the surface.)
  • Parkfield Model (Seismograms for the Parkfield Model)
