S-to-Rayleigh wave scattering from the continental margin observed at USArray

We show new observations of body‐to‐surface wave conversions at the U.S. continental margin observed with USArray. Simulation results show how simple surface topography at the coastline can successfully generate scattered Rayleigh waves from incident SV waves. These converted surface waves may be an important source of signal‐generated noise in continental seismology, in particular in studies of seismic phases and parts of the wavefield between direct S and later‐arriving surface waves from the source.
