The Caribbean is one of the regions in the world most at risk of natural disasters. This is particularly the case with the French territories of the West Indies. Guadeloupe is directly threatened by six major natural hazards: earthquakes, volcanic eruptions, cyclones, tsunamis, floods, terrain movements. In recent decades Guadeloupe has been affected by major natural disasters of different natures: earthquakes (Saintes, 2004), floods (including sudden flooding), hurricanes (Hugo in 1989, Marilyn in 1995, Dean in 2007, Maria in 2017), etc. These major risks are exacerbated by various factors of vulnerability of populations and territory: insular or even “double insularity” of dependencies, socio-economic fragility of part of the population, complex migration flows, urban densification and strong urban pressure, rapid erosion of risk memory. Moreover, these risks of disasters are increased by a process of climate change that affects the frequency, intensity and unpredictability of hazards, requiring sustained effort and pace of adaptation by people and institutions. In addition to this socio-environmental context, it is noted that: The culture of risk is difficult to progress at the population level and knowledge of risks is heterogeneous, as well as that of appropriate behaviours in the event of disasters. This requires an increase in the
