What drives Brazil's disaster profile
Across the 30 Brazil cities in our data, the three highest average exposures are flooding (3.5/5), extreme heat (2.1/5) and drought (1.5/5). These reflect geography rather than chance: earthquake tiers come from real USGS records of magnitude-4.5+ events within 300 km, storm risk from position in a tropical-cyclone basin, flood from rainfall regime and low-lying terrain, and wildfire/heat from Köppen climate zone. The full modelled profile for Brazil is flooding 3.5/5; extreme heat 2.1/5; drought 1.5/5; wildfire 1.2/5; earthquake 1.1/5; storms (hurricane/cyclone) 1.0/5; extreme cold / winter 1.0/5; tsunami 1.0/5. Use it as a relative guide between cities — a high tier means plan for it (insurance, building codes, location within the city), not that disaster is certain. City pages break each hazard down individually.
Brazil disaster exposure by type
- flooding: 3.5/5 — moderate — worth verifying for your specific neighbourhood.
- extreme heat: 2.1/5 — low — a minor consideration.
- drought: 1.5/5 — negligible in our model.
- wildfire: 1.2/5 — negligible in our model.
- earthquake: 1.1/5 — negligible in our model.
- storms (hurricane/cyclone): 1.0/5 — negligible in our model.
- extreme cold / winter: 1.0/5 — negligible in our model.
- tsunami: 1.0/5 — negligible in our model.
For relocators, the practical takeaway is to match the hazard profile to your housing choice: where flood or storm tiers are elevated, favour higher ground and modern drainage; where the earthquake tier is high, prioritise post-code seismic construction; and budget for the insurance lines that the leading hazards in Brazil will drive. The safest single city in our Brazil sample, Curitiba (safety 69/100), is the natural starting point if low disaster exposure is your top filter.
