Implication

Simulation study demonstrates marked spatial variation in tsunami inundation across 11 coastal cities, highlighting the necessity of site-specific hazard mitigation planning.

Key Points

Tsunami inundation maps reveal substantial spatial variability across coastal communities, showing that regional geography strongly modulates local flooding risks.
Analysis across 11 coastal cities evaluated earthquake magnitudes from 8.0 to 9.6, identifying distinct vulnerability profiles along the subduction zone.
Simulation using the NEOWAVE model supports localized hazard planning, demonstrating that uniform national building standards fail to address site-specific threats.
