Flooding is the most frequent natural disaster in Mexico, affecting tens of thousands of people each year. Although often less dramatic than earthquakes, they cause considerable economic damage and population displacement.
High-risk basins include the Grijalva-Usumacinta River in Tabasco and Chiapas, the Papaloapan River in Veracruz, and the Bravo River in the north. Flooding in these regions is aggravated by dams, deforestation, and climate change that intensifies extreme rainfall.
The 2010 Tabasco flooding was particularly severe, with water levels reaching up to 4 meters in some urban areas. Climate change projects increasing frequency and intensity of extreme precipitation, raising the risk of catastrophic floods.
Assessing flood risk is essential before buying a property. Consult historical flood maps, ask neighbors about past floods, and research local building policies regarding floodplains.
