ONC helps coastal communities prepare for and improve their resilience to natural hazard events including tsunamis and storm surge, as well as sea-level rise due to climate change. Canada’s diverse geography and geomorphology, including fiords, arctic tundra, river deltas, bluffs and sandy or rocky beaches, means hazard impacts vary considerably along the coast.
ONC supports tsunami resilience in at-risk coastal communities by integrating detailed geographic mapping into sophisticated propagation models, allowing communities to prepare safety plans for expected inundation levels and current velocities.
Our activities and services include:
Using these results, Indigenous partners and coastal communities can identify next steps for emergency response and tsunami risk mitigation, and inform project stakeholders and the public.
