Chiou and Youngs PEER-NGA Empirical Ground Motion Model for ...

Figure B-2: Data for aspect ratio versus M from PEER-NGA finite fault model set.
Symbol color denotes faulting style (black SS, red NM, and green RV).
The next step was to locate the rupture plane in space. The vertical location of the
simulated rupture with respect to the hypocenter was simulated using empirical
distributions for hypocenter location derived from the PEER-NGA set of rupture models.
The observed and smoothed empirical distributions are shown in Figure B-3. If the top of
the simulated rupture plane extended above 0 depth, it was placed at 0 depth. The rupture
plane dip was fixed at the value assigned to the earthquake.
The location of the hypocenter along strike was simulated using data from Mai et al.
(2005) for earthquakes ≤ M 6.5. This distribution is shown in Figure B-4.
