A hazard is a natural or human-induced event that can potentially cause harm. A risk refers to the likelihood that this hazard will cause damage to people, property, or the environment, depending on exposure and vulnerability. In other words, the hazard is the potential cause, while the risk includes its probable impacts.

Hazards

A few figures

Tropical storms in 2024

10 directly affected the Caribbean Sea and the Gulf of Mexico. Among these storms, 11 became hurricanes.

863 Earthquake

according to historical data and seismic archives. Among them, 5 earthquakes reached a magnitude of 5 or more

This is the number of active volcanoes in the Caribbean

millions of inhabitants affected by natural risks in the Caribbean and Latin America according to the UNFPA (United Nations Population Fund)

billion euros: this is the total cost of Hurricane Irma in 2017 according to the National Hurricane Center

Differences in the Caribbean

According to the University of Caen Normandy, while the if the Caribbean is particularly exposed to hazards,territories are not equally affected: some are more vulnerable than others.

Composed mainly of islands, the Caribbean is often hit by violent tropical storms, cyclones, and tidal wavesThe majority of the population living on the coast, it is therefore particularly exposed to natural risks. (Source : University of Caen Normandy – Atlas Caribbean – “Societies facing risks: the case of the Caribbean”))

Le Climate changea more global phenomenon, can also have an impact on certain natural risks, such as cyclones whose scientists predict an increase in intensity or droughts that will be more frequent, with longer dry seasons and shorter wet seasons.

The recurrence of tropical storms and tidal waves should not however, make us forget the other risks present in the region, namely: earthquakes, ground movements, volcanic eruptions, and floods.
