Pagination or Media Count:
The first section describes the observations of first-order mantle reverberations and develops techniques for using these data to constrain upper-mantle velocity and attenuation structure. The second section discusses our work on the waveform inversion of higher-mode surface waves, and the third analyzes the resolving power of the higher-mode data set. The fourth section reviews recent progress in seismic tomography and its implications for mantle dynamics. The fifth section applies methods for the representation and recovery of seismic source parameters to two recent earthquakes.
