Animation of normal traction, shear traction, slip, peak slip rate, and slip
rate on the fault surface for model 4T. Vertical lines mark changes in strike
between planar segments. The star marks the nucleation point at 5 km depth.
On each plot, slip path length is contoured at the initiation of rupture and at
the slip-weakening distance, so the distance between the two contours indicates
cohesive zone width. The rupture follows areas of high initial shear traction,
and is slowed where it enters low traction areas, causing focusing of the
rupture front in some cases.

Animation of surface velocity magnitude over three minutes of simulation time.
Yellow indicates stronger velocities, exceeding 25 cm/s. Shock fronts due to
super-shear rupture velocity are visible north of Palm Springs at around 45
seconds. Channeling of energy in to the basin wave guide near San Bernardino
begins at about 60 seconds. Basin reverberations last well after the initial
wave front has past, and are still present at the end of the simulation.
