TeraShake 1 & 2 models earth shaking that could rattle Simulations Southern California if a 230 kilometer section of the San Andreas fault ruptured producing a magnitude 7.7 earthquake. The simulation consists of 7 different simulations, 4 in phase one and 3 in phase two yielding a total of 160 TB of data. We have done visualization of portions of this data with a variety of methods for scientific investigation and dissemination. There are over 130,000 images and more than 50 unique movies created in this project.
