Researchers from the University of Southern California and the Southern California Earthquake Center are using ALCF supercomputers to enhance earthquake simulation and hazard mapping tools to provide the best possible information in terms of earthquake ground motion and seismic hazard. This video shows a magnitude 7.6 earthquake with rupture propagation and resulting wavefield at the surface computed by the dynamic rupture code SORD along a vertically dipping strike-slip fault with superimposed fault roughness. The advancement of earthquake modeling and simulation tools is critical to reducing uncertainties and improving the accuracy of seismic hazard assessments, enabling the development of design and mitigation strategies that save lives and reduce economic losses.
