Computer simulation of the Mw 7.1 Iniskin, Alaska, earthquake (January 24, 2016)
Computer simulation of a magnitude 7.1 earthquake on January 24, 2016 in the Cook Inlet region of Alaska. The 3D simulation demonstrates the complexity of the seismic wavefield that arises from realistic models of Earth structure. We see a striking effect due to the slow wave speeds within Cook Inlet sedimentary basin. The simulation was performed on the high-performance computing cluster at the University of Alaska Fairbanks, Research Computing Systems. The 3D wave propagation code is called SPECFEM3D.
