Wave Propagation Animations

All simulations were computed on sanddunearch at the University of Utah Center for High Performance Computing.

Global Seismic Wave Propagation simulations were computed with the SHaxi and PSVaxi methods. The SHaxi source code can be downloaded at the SPICE webpage.

To save an animation 'right click | save target as...' on the desired resolution. All files are in windows media (.wmv) format in high definition (either 1080p or 720p).

Animations were generated using a combination of the GMT, ImageMagick, and POVRay software packages.

Ray paths and wavefronts were drawn using the TauP Toolkit.

If you download any of these animations you implicitly agree to give proper credit to the authors. Acknowledgement should be given to:

Michael S. Thorne, H. Philip Crotwell, Gunnar Jahnke, and Heiner Igel.

Software development that made the production of these animations possible was partially supported through NSF Grants EAR-1014749, EAR-0952187, and NASA Grant NNX11AH47G.
