I. The distribution of tsunami amplitudes in the open ocean is controlled by source mechanism and bathymetry geometry. Although detailed studies have considered heterogeneity effects in earthquake tsunami sources, little or no attention has been paid to the effects of physical resolution of detailed bathymetry on tsunami waveforms in the...
The structure of the North American crust and mantle was investigated using P wave teleseismic tomography and the links between seismic tomographic models, locations of volcanism, sediment isopachs, and continental scale crustal structures via plate reconstruction modeling. Nearly 50,000 teleseismic P wave delay times were measured from seismograms recorded by...
