Landslide risk in Haiti and land management in Port au Prince

This thesis aims to identify landslide risk zones in Haiti as a whole (regional scale) and Port au Prince specifically (local scale) and to evaluate how this landslide risk can affect them, especially to Port au Prince, in order to elaborate recommendations in priority zones of the city. Landslide risk priority zones are marked in order to apply land management recommendations supported in the Haitian land tenure to reduce, mitigate or delete at maximum the possible damages that these zones can suffer in the future due to landslides. These recommendations are collected in order to stakeholders decide which of them are the best options for each priority zone. Different types of maps are generated in order to locate all landslide risk zones and priority zones.

Multi-hazard analysis and identification of priority settlements for land management in Haiti

Seismic hazard study in “La Hispaniola” island in connection with the land tenure situation in the region, in order to define priority areas with a high risk, where some land management recommendations are proposed. The seismic hazard assessment has been carried out following the probabilistic method with a seismogenic zonation and including the major faults of the region as independent units. In order to identify the priority areas, it has taken into account, besides the seismic hazard study, the map of changes of static Coulomb failure stress and the landslide hazard map.
