ShakeMovies

SCEC researchers have produced several types of earthquake and ground motion movies and animations. SCEC Visualization groups include SDSC, PSC, ISI, USC, and SCEC Interns.

Examples of SCEC Earthquake Animations

Thumbnail	Animation Number	Animation Description
Fig 1: Puente Hills Earthquake Animation Movie (Image Credit: Robert Graves (USGS), Amit Chourasia Steve Cutchin (SDSC))	Animation_1	Puente Hills Wave Propagation Simulation. Animation showing the propagation of ground motions across the Los Angeles Basin.
Fig 2: TeraShake Earthquake Animation Movie (Image Credit: Kim Olsen (USGS), Amit Chourasia Steve Cutchin (SDSC))	Animation_2	TeraShake 2.1 Simulation with Narration - Overview of the earthquake hazards using TeraShake ground motion simulation. Animation shows both map-based views and volume-based visualizations of wavefield.
Fig 3: M8 Wave Propagation Map View Movie (Image Credit: Amit Chourasia, Steve Cutchin, Yifeng Cui (SDSC), Kim Olsen (SDSU)	Animation_3	M8 Map View - Animation showing the M8 California earthquake rupture in a map view format.
Fig 4: M8 Velocity Mag as Height Field (Image Credit: Amit Chourasia Steve Cutchin Yifeng Cui (SDSC), Kim Olsen (SDSU)	Animation_4	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.
Fig 5: ShakeOut Simulation (Image Credit: Robert Graves (USGS), Amit Chourasia, Yifeng Cui (SDSC), Geoff Ely, Philip Maechling (SCEC)	Animation_5	Shakeout Map View - ShakeOut earthquake animation showing ground motions in a map view.
Fig 6: M8 Wave Propagation Movie (Image Credit: Emmett McQuinn (UCSD), Amit Chourasia (SDSC)	Animation_6	GlyphSea Narrated Animation of M8 - Narrated animation showing GlyphSea vector visualization technique applied to M8 ground motion simulation data.
Fig 7: ShakeOut Earthquake from Long Beach (Image Credit: Brad Aagaard, Amit Chourasia Steve Cutchin (SDSC), Mark Benthien (SCEC)	Animation_7	Shakeout_Long_Beach_Perspective - ShakeOut earthquake animation showing ground motions from the perspective of a site in Long Beach California. The animation shows the ground motions approaching from the south, then long lasting long period motions throughout the city.
Fig 8: 18 Story Steel Frame Building Response to M8 Ground Motions (Credit: Swaminathan Krishnan (Caltech), Sandarsh Kumar, Philip Maechling (SCEC))	Animation_8	Building Response Animation (M8 at Northridge) - Animation of response of a 18 story steel frame building to M8 ground motions in Northridge California.
Fig 9: M8 Wave Propagation Movie (Image Credit: Amit Chourasia (SDSC), Swami Krishan (Caltech), Phil Maechling (SCEC)	Animation_9	M8 Building Response for Multiple Sites in Los Angeles - Animation showing response of multiple 18 story steel frame buildings to M8 ground motion simulation data.
Fig 10: Northridge Earthquake at Pacoima (Image Credit: Philip Maechling (SCEC))	Animation_10	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.
Fig 11: TeraShake Rupture Directivity Comparison (Image Credit: Amit Chourasia, Steve Cutchin, Marcio Faerman (SDSC)	Animation_11	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.
Fig 12: Brawley Seismic Zone Dynamic Rupture (Image Credit: Christos Kyriakopoulos)(Univ of Memphis/CERI))	Animation_12	This video shows four different dynamic rupture models, all based on a postulated network of faults in the Salton Sea area, southern California. The hypocenter of these events is placed on the San Andreas fault and approximately 30km north of Bombay beach. The first seconds of the simulations show the initiation phase of the earthquake, also known as the “nucleation phase”. After this initial phase, the earthquake rupture propagates spontaneously towards the right-hand side of the screen (south-east in the map).
