Abstract & Bio
Earthquake Scenarios for Community Resilience
Dr. Tiegan Hobbs, Seismic Risk Scientist/Geological Survey of Canada - University of British Columbia
To prepare for and respond to natural hazards, decision makers require a robust and well-communicated base of evidence. For earthquakes, the Geological Survey of Canada seeks to meet this need with our upcoming National Seismic Risk Profile. This model includes a probabilistic risk assessment and a catalogue of earthquake scenarios, all of which will be accompanied by guidelines for use. A purpose-built web platform is currently under development, as well. In this presentation, we will learn more about the National Seismic Risk Profile and walk through a magnitude 9.0 Cascadia earthquake scenario. We will look at relevant impacts, such as injuries, fatalities, housing disruption, damages, financial losses, and generation of debris in British Columbia communities. We will also touch upon possible retrofit scenarios, with a goal of empowering practitioners to utilize these tools for emergency management, community planning, and other risk mitigation measures.
Dr. Tiegan Hobbs is a seismic risk scientist for the Geological Survey of Canada and an adjunct professor at the University of British Columbia in the Earth, Ocean, and Atmospheric Sciences department. She uses various geologic, geophysical, and geotechnical datasets to better understand active tectonics and natural hazards. Specifically, she is interested in understanding how the stresses that cause potentially catastrophic events are accumulated through time and space, how failure is ultimately initiated, and what the impacts will be for communities and the built environment. She is leading the development of the scenario earthquake catalogue for Canada’s first National Seismic Risk Model, including validation of the framework against known standards.
With a passion for communicating risk, Tiegan has written over 20 articles for Temblor Earthquake News. She is a member of the Centre for Natural Hazards Research at Simon Fraser University and serves as co-chair of the American Geophysical Union Hazards Equity Working Group. She has also been volunteering in K-12 classrooms with the ‘Skype a Scientist’ organization for several years. Tiegan received her PhD in Geophysics and Masters of Geotechnical Engineering from the Georgia Institute of Technology, a Masters of Geophysics from the University of Victoria, and a Bachelors in Geology from McGill University.
