Tsunami assessment
Assessment: Shallow megathrust-scale event with significant tsunamigenic potential, especially if located offshore. Shallow (<70 km) offshore earthquakes of M7+ are the primary driver of seismic sea waves; depth, location relative to the coast and seafloor displacement govern the actual hazard.
Geotechnical relevance
For coastal geotechnical engineering in Canada, tsunami hazard influences site selection, coastal foundation design, scour and liquefaction in saturated coastal sands, and the resilience of port and waterfront structures. Monitoring tsunamigenic events informs run-up and inundation assumptions.
