- Abstract
- ;Contents: Introduction; Stratigraphy and structure across the San Andreas fault zone in the Loma Prieta region and deformation during the earthquake; Geophysical and geologic setting of the earthquake, inferred from gravity and magnetic anomalies; Deep geoelectrical structure of the Loma Prieta region; Evidence for oceanic crust beneath the continental margin west of the San Andreas fault from onshore-offshore wide-angle seismic recordings; Three-dimensional tomographic analysis of the Loma Prieta region; Three-dimensional variations in VP /VS ratio in the Loma Prieta Region; Seismotectonics of the Loma Prieta region determined from three- dimensional P-wave velocities, VP /VS ratios, and seismicity; Teleseismic tomography of the Loma Prieta region: Implications for strain partitioning.
