High-fidelity modeling of the propagation of seismic waves through the earth.

High-fidelity modeling seismic wave propagation improves seismic hazard assessments.

Advanced computing enable high-fidelity modeling of the propagation of seismic waves through the earth, which will help provide a better understanding of the structure of earth's interior, and will help improve assessments of seismic hazard. Solving the seismic wave propagation equations to frequencies of interest taxes existing supercomputers. Stampede provides the computational resources needed to incorporate earthquake observations into improved earth models through inverse theory.
