Subduction Zone Dynamics
Teconic model for earthquake hazards evaluation. The northern Cascadia subduction zone has been hypothesized as the potential location for a large megathrust earthquake. Evidence for past great earthquakes on the subduction zone is extensive.

Coastal and Marine Geology
Reports from seismic reflection studies on the structure off-shore and beneath the Cascadia region; tsunami modelling reports

EXTERNAL PROGRAM
Summaries from our cooperators at universities throughout the nation on a variety of subjects. Use lists to find reports by year and location.
