Visualizations

This is a collection of SCEC Ground Motion simulation visualizations.

Ground Motion Simulation 4D Dataset

TeraShake2 Simulation data

SCEC worked with IEEE animation group in 2006 to provide and define a 4D (x,y,z,t) earthquake simulation dataset that could be used in an IEEE visualization contest. The SCEC IEEE earthquake simulation data set (4D dataset) (2006) is posted online. The web pages contain descriptions of the data, and links to where the data can be downloaded.

Example Ground Motion Animations

Map view of M8 ground motions (144MB) .mov format

This map view animations shows the M8 rupture propagation south on the San Andreas Fault in southern California using Ely style color-scales. Based on the file-metadata these ground motions are based on the y-component of motion. (Amit Chourasia, Geoff Ely, et al 2010)

Statewide Rupture (10.5MB) .mp4 format

Ground motion simulation for State-wide California Earthquake using paraview. (Scott Callaghan et all 2016)

Plastic Yield Viz (YouTube)

Rupture simulation showing Plastic Yielding (Dan Roten et al 2015)

Fault and Wave propagation rupture comparison (120.8MB) .mov format

Fault and wave propagation animation comparing waves from smooth fault and velocity model to waves from rough fault and velocity model with small scale heterogeneities. (Kim Olsen et al 2014)

M8 simulations using perspective and Height Field (124.8 MB) .mov format

The M8 animations that follows the rupture from central California to Mexico, showing velocity magnitude as height field. (Amit Chourasia et al 2010)

Wall to Wall simulations comparing effects of N-S, S-N, and bi-lateral ruptures (48.8 MB) .mov format

Comparison showing difference in ground motions produced by North to South, South to North, and Bi-lateral San Andreas ruptures (Kim Olsen et al 2009)

Glyphsea Technique used to show ground motions vectors from bi-lateral San Andreas Rupture (11.3MB) .mov format

Map view animation using Glyphsea visualization for wall to wall San Andrea bi-lateral rupture (Amit Chourasia, Kim Olsen, Yifeng Cui et al)

Side-by-Side Comparison of ShakeOut Earthquake from 3 methods (27MB) .mov format

Map view animations showing side-by-side comparison of ground motions produced by 3 different ground motion simulation methods (Graves, AWP, and Hercules).

M8 Earthquake Rupture shown using GlyphSea Viz Technique (93.8MB) .mov format

Demonstration of experimental vector visualization technique (Glyphsea) applied to M8 rupture (Amit Chourasia, Kim Olsen, Yifeng Cui et al 2010)

Dynamic Rupture Simulations

Fault Rupture Comparison (6.7MB) .mov format

Comparison showing rupture on fault surface from a dynamic rupture simulation and from a kinematic simulation. Shows only the fault surface and not the ground motion values.

Comparisong of multiple ShakeOut Rupture Simulation (45MB) .mov format

Fault surface slip animations comparing results from kinematic rupture and multiple ShakeOut dynamic rupture simulations (Steve Day, Kim Olsen et al 2008)
