  abstract = {{T}he drive towards improving tsunami risk mitigation has intensified along many populated coastlines. {L}ike many islands in the {P}acific {O}cean, the coastal population of {N}ew {C}aledonia is exposed to tsunamis triggered by powerful earthquakes. {I}ntersecting exhaustive population data with high-resolution building location data within a user-defined coastal fringe is an accurate means of geolocating vulnerable residents, and an important step towards disaster risk reduction. {T}his paper presents a mixed methodology built on {GIS}-based dasymetric techniques for assessing, classifying, and mapping population distribution in {N}ew {C}aledonia, with the aim of quantifying and ranking the areas most vulnerable to tsunami-related hazards. {R}esults reveal that 33% of the population, inclusive of previously unmapped precarious housing, lives between sea level and the 10 m elevation contour in well-defined clusters. {A} pilot field survey of 412 respondents was additionally conducted in the capital {N}oume ' a (66% of the nation's population) to assess tsunami awareness, risk perception, and risk-related behavioral patterns among the ethnically and demographically diverse population. {B}y further mapping the spatial association between coastal population concentrations, the perceived natural shielding capacities of coral reefs and mangroves, and the benefits of alarm siren networks, the study delivers a comprehensive assessment of the country's disaster preparedness, with policy recommendations for the future. {T}he methodology is transferable to other types of hazards and other insular settings where civil security and risk-management organizations acquire and curate reliable primary data but may also need guidelines for transforming them into serviceable disaster risk reduction methods and policies.},
