Comparison of Velocity Magnitudes For TeraShake Ruptures – This animation compares two equivalent TeraShake Ruptures on the San Andreas Fault. Both ruptures are identical except for the slip direction. This animation shows multiple variables in an understandable way including location and magnitude of the instantaneous peak velocity in both ruptures, the distribution and magnitude of peak ground motions for both ruptures, and the rupture and wave propagation time and duration.

M8 Perspective – Animation showing the north to south M8 California earthquake rupture, with a perspective above the fault. The amplitude of the ground motion is shown as exaggerated topography. The animation shows a seismic shock waves is formed at the rupture front, and a strong stopping pulse as the rupture ends south of the Salton Sea.

GlyphSea Narrated Animation of M8 – Narrated animation showing GlyphSea vector visualization technique applied to M8 ground motion simulation data. (Image Credit: Emmett McQuinn (UCSD), Amit Chourasia (SDSC)

EQ_Northridge_Site_Pacoima – Simulation showing the effects of ground motions on objects in Pacoima, about 12km from epicenter of Northridge Earthquake. The animation was created by retrieving the observed ground motions from a Pacoima strong motion station for the Northridge earthquake, then inputting these seismograms into a scene containing everyday objects, and using a physics-engine to show the results of the ground motions on the objects.
