Simulation of a hypothetical (fictional) magnitude 7.6 earthquake with rupture propagation and resulting wavefield at the surface along a vertically dipping strike-slip fault with superimposed fault roughness.

The simulation was computed by the dynamic rupture code SORD on the Theta high-performance computer at the Argonne Leadership Class Facility through an INCITE allocation award.

This is a theoretical model, not a simulation for an earthquake that has already occurred or may occur on a real, known fault.

The advancement of earthquake modeling and simulation tools such as this 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.
