Earthquake and Tsunami Science and Technology: Recent Advances for Port Alberni - Tania L. Insua, PhD

This presentation will cover the basics of earthquake and tsunami science for the particular case of Port Alberni. Existing and new instruments for tsunami detection, including DART buoys from the US National Oceanic and Atmospheric Administration as well as the closely located instruments from Ocean Networks Canada will be described and discussed. Recent tsunami modelling efforts for a future Cascadia rupture, similar to the one that impacted Port Alberni and the coast of Vancouver Island in the 1700, will also be presented.

Future Damage Potential from Earthquakes and Tsunamis in Port Alberni - Tuna Onur, PhD

This presentation focuses on impact of earthquakes and tsunamis on current and new building stock. Damage potential to current buildings are typically assessed using building vulnerability and fragility functions developed based on the construction characteristics of the building stock, past damage experience and computer simulations. The presentation will cover the current state of knowledge and what would be needed to make estimates of future damage from earthquakes and tsunamis in Port Alberni. Ability to withstand seismic and tsunami loads is also affected by building code requirements. While the National Building Code of Canada has seismic provisions for buildings, it currently has none for tsunamis. The US building code's latest edition (2016) includes, for the first time, tsunami design provisions for buildings. Canada is currently considering similar tsunami provisions to reduce vulnerability of buildings to tsunami impact.

Bio - Tuna Onur, PhD
Dr. Onur is a disaster risk consultant specializing in the modelling and communication of earthquake and tsunami hazard, structural vulnerabilities and financial losses both nationally and internationally. She has over 20 years of experience in all aspects of earthquake risk estimation and currently serves on the National Building Code of Canada's Standing Committee on Earthquake Design. Her professional experience includes both private and public sector positions as hazard researcher, as lead catastrophe risk modeller, and as a subject matter expert advising engineering firms, governments, the insurance industry and financial regulatory agencies. Dr. Onur is also involved in various international capacity building initiatives integrating probabilistic hazard assessments with modernization of building codes, and was one of the core authors of UNISDR's Disaster Risk Assessment Guidelines. She teaches earthquake engineering at the University of Victoria and continues to be actively involved in disaster risk related research.

Bio - Tania L. Insua, PhD
Dr. Insua coursed her bachelor in Marine Sciences at University of Vigo, Spain. She did her Masters and PhD in Ocean Engineering at University of Rhode Island, USA. In her current work at Ocean Networks Canada (ONC) as the Ocean Analytics Program Manager she is in charge of the ONC Tsunami Program. The ONC Tsunami Program covers multi-system detection of tsunamis with cabled observatories, source modelling, digital elevation models, wave propagation modelling and virtual reality. She also manages and participates as a technical lead in other projects and operations at ONC.
