The course will focus on ground motion that is recorded near the earthquake source. How are the ground motions related to the dynamics of faulting? The course will start with a description of ground motion from a point source and move on to ground motion from a finite fault. Topics that will be covered are the parameters of a spectral model of an earthquake such as stress drop, seismic moment and corner frequency (Aki, 1967, JGR and Brune 1970, JGR), directivity effects due to rupture velocity, polarization of ground motion, spatial variation from radiation pattern effects, isochrones, attenuation and site amplification due to local structure.
