Structural Geology and Active Tectonics
Beatrice Tinsley Rm 218


Research Interests

Active tectonics and structure along the New Zealand (North Canterbury and east coast North Island) and southern California (western Salton Trough) plate boundary zones. Structural geomorphology in transpressional settings, especially the role of topographic loading with respect to near-surface fault zone geometry. The role of tectonic and climatic forcing in triggering large bedrock controlled landslides in landscape evolution. Hikurangi Margin soft-rock terrain, eastern North Island. Engineering geology, particularly slope instability, paleoseismicity and earthquake hazard assessment.
