3D Regional Wave Propagation With Q(f) in East Asia

Abstract

This first annual report for FA9453-16-C-0017 provides a review of work accomplished, work in progress, and next steps. We collaboratewith Scott Phillips and Mike Begnaud of LANL to use 3D high-performance computing to reproduce high-frequency (<4Hz) regionalrecords (450km+) from the seismic sources at the North Korea nuclear test site (NKNTS). The project constrains the crustal parameters, interms of seismic velocities, densities, frequency-dependent an elastic attenuation, and distributions of small-scale heterogeneities, requiredto match the observed records. The results help understand the nature of crustal scattering on the Korean Peninsula, and have implicationsfor methods used for discrimination between explosive and earthquake sources.
