Green's functions are fundamental solutions to the wave equation for an idealized impulse localized in space and time. They are fundamental to seismology because we use them to construct general solutions for the study Earth structure and to understand the earthquake source. In the past decade, seismologists have developed the ability to estimate these solutions from the ambient seismic field, which is present in the Earth at all times, by comparing signals that were observed by multiple seismic instruments. Most efforts in this area have focused on improving models of Earth structure, but in my talk I will demonstrate that the ambient seismic field can also be used to predict variations in strong ground motion from large earthquakes.
