    The Big One


Company / Institution / Agency:

  • San Diego Supercomputer Center


    This animated visualization illustrates some of the rupture and wave propagation phenomena of a magnitude 7.8 earthquake on the San Andreas fault in southern California (“The Big One”). The animation captures more than four minutes of the complex dynamic rupture and wave propagation, including directivity effects, wave-guide phenomena, and local amplification of the ground shaking. The visualization presents these physical effects in an intuitive yet accessible manner, using a variety of visual representations and several views. The animation uses 11.8 terabytes of earthquake simulation output from a state-of-the-art earthquake simulation.
