Abstract: The subsurface structure of Alaska contains clues to its formation and evolution over geologic time. Today, tectonic forces of subduction and collision are manifest in earthquake activity across the entire state. The NSF-sponsored EarthScope Seismic Array was fully deployed in 2017, enabling new high-quality geophysical data collection in large, remote regions of the state. I will discuss recent and ongoing studies of earthquakes and seismic imaging in Alaska, with a focus on crustal faulting. I will also convey how 3D seismic wavefield simulations can be used to understand the complexities of the recorded wavefield, as well as to guide improvements to tomographic models of crustal and upper mantle structure.
