- Title
- Canada’s Tsunami Hazard in the Pacific: Cascadia Subduction Earthquakes
- Abstract
- Cascadia subduction events are major threats for coastal cities and towns in British Columbia (BC). If they occur, their magnitudes will be M9, and catastrophic shaking as well as tsunami will be caused. Communities in Vancouver Island are exposed to these threats. In addition to the tsunami hazards themselves, there are high possibility and uncertainty that the sea level in BC coasts may be rising due to climate change in future. The Geological survey of Canada has reported likely climate change scenarios. In the context of tsunami hazard, relative sea level rises could have major effects on tsunami inundation. The talk presents the most recent research results about probabilistic tsunami hazard assessments due to the Cascadia subduction events along Canada’s Pacific coast. The analyses adopt stochastic source modelling methods to account for a wide range of possible earthquake ruptures of the Cascadia events. The results are discussed from the future perspectives of rising sea level risk in this region.
