Blind Thrust Fault Earthquake Rupture Animation Northridge 1994

Blind Thrust Fault Earthquake Rupture Animation (Northridge, 1994) Brad Aagaard, USGS http: //pasadena. wr. usgs. gov/office/baagaard/research/animations. html The fault rupture will be visible in the animation. Displacements (magnified 3000 times) will be visible by the movement of the mesh from the model. The amplitude of motions and seismic waves is color coded according to ground velocity. http: //web. ics. purdue. edu/~braile/new/Aagaard. Blind. Thrust. Animation. ppt Exploring Planet Earth
