This inter-disciplinary course focuses on the dynamics of potentially hazardous geological events and the connections between geodynamics and societal risk.
This course focuses on the processes of geological hazards and how they impact on society. Some attention is given to techniques and strategies for hazard mitigation. Lectures on the tectonic evolution of New Zealand provide a framework for understanding contemporary earthquake, volcanic, flood and landslide hazards. Topics such as earthquakes, volcanic eruptions, liquefaction, rockfall, and flooding will all be addressed. Case studies revealing how natural and human environments were impacted by these hazards and how these hazards were successfully (or unsuccessfully) mitigated will be presented. Students taking this course will gain an understanding of the fundamentals of geological processes and impacts that will greatly benefit those wishing to do further tectonics and/or geohazards research.
Goal of the CourseStudents will understand how geological hazards operate at the process level, and how geohazard behaviour over spatial and temporal time-scales influences how hazards are assessed and mitigated.Learning OutcomesStudents successfully completing this course will:Understand how New Zealand’s tectonic evolution and modern tectonic setting influences the locations and magnitudes of contemporary earthquake, landslide, and volcanic hazardsUnderstand the fundamentals that govern geohazard behaviour in both time and spaceUnderstand the links between hazards (e.g., seismically-triggered landslides, volcanically-triggered debris flows)Know how to develop risk assessments from hazard behaviour Understand the links between hazard behaviour and societal riskSummary of the Course ContentThe topics coved by this course are:Introduction to geohazardsActive tectonics of New ZealandEarthquake science and paleoseismologyGeomorphic hazardsLandslides, rockfall, and rock fracturingFloodingHazards of eruptions: lava flows, pyroclastic density currents, lahars, ash fall and volcanic gasRisk assessment and mitigation of geological hazardsRisk and hazard communication
