Fault With Bottle Neck

    Shown is the xz-plane of the model and the y-component of seismic velocity.

    The seismic properties of the surrounding quarter spaces are

  • p-velocity: 5.00 km/s
  • s-velocity: 3.50 km/s
  • density: 2.35 g/cm^3
  • The FZ properties are 30% reduced with respect to the background.
    In the lower fault segment a FZ-wave  emerges. Arriving at the bottle neck region some trapped energy radiates in the surrounding quarterspaces.
    This moderate loss of energy decreases the FZ-wave amplitude but the change of FZ-shape is not capable of destroying the FZ-waves.
