Cartographie des enjeux côtiers et de l’aléa tsunami en Nouvelle-Calédonie

Abstract : New Caledonia has nearly 70% of its population living less than one kilometer from the seaside. This littoralization of human activities significantly increases the risk associated to tsunamis. The government of New Caledonia, in partnership with the IRD in the TSUCAL project, wishes to realize tsunami hazard mapping. This will help to create risk and evacuation maps. The work focuses first on the mapping of the coastal issues of New Caledonia by defining precise location of the population and the building, by studying factors of vulnerability, by looking at the impact of the evacuation alert sirens and by understanding how some ecosystems can protect the coast and its population from tsunamis. Finally, tsunami hazard mapping on the New Caledonian coast represents the maximum possible height of the tsunami at any point along the coast.
