Analysis of Multiple Natural Hazards in Haiti (NATHAT)
- Combines ground-motion and hydrometeorological hazards into weighted multi-hazard scenarios rather than assessing each separately.
- Applies the Mora-Vahrson macrozonation method, which is what makes its hazard maps comparable to other countries' assessments.
- Written two months after the January 2010 earthquake, so it treats the earthquake as an aggravating factor on pre-existing vulnerability rather than as the whole problem.
- Authored by the Government of Haiti with World Bank support, not by the Bank alone.
The multi-hazard assessment prepared by the Government of Haiti with World Bank support, dated 26 March 2010, two months after the January earthquake. It maps ground-motion hazards including landslides, mudslides and debris flows alongside hydrometeorological and climate-related hazards, applies the Mora-Vahrson macrozonation and a superposition model to combine them into multi-hazard scenarios by relative weight, and examines how the earthquake aggravated existing vulnerability. NATHAT is the reference multi-hazard baseline for post-earthquake reconstruction planning.
