Natural-disaster risk in Mauritius

In Mauritius, the leading natural-disaster exposures are flooding, storms (hurricane/cyclone), extreme heat. The safest city for disasters is Beau Bassin-Rose Hill (safety 67/100). Risk is modelled from real USGS counts of magnitude-4.5+ earthquakes within 300 km since 1980 plus Köppen climate zones and cyclone/subduction geography.

What drives Mauritius's disaster profile

Across the 9 Mauritius cities in our data, the three highest average exposures are flooding (3.8/5), storms (hurricane/cyclone) (3.2/5) and extreme heat (2.0/5). 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 Mauritius is flooding 3.8/5; storms (hurricane/cyclone) 3.2/5; extreme heat 2.0/5; drought 1.4/5; earthquake 1.0/5; wildfire 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.

Mauritius disaster exposure by type

flooding: 3.8/5 — moderate — worth verifying for your specific neighbourhood.
storms (hurricane/cyclone): 3.2/5 — moderate — worth verifying for your specific neighbourhood.
extreme heat: 2.0/5 — low — a minor consideration.
drought: 1.4/5 — negligible in our model.
earthquake: 1.0/5 — negligible in our model.
wildfire: 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 Mauritius will drive. The safest single city in our Mauritius sample, Beau Bassin-Rose Hill (safety 67/100), is the natural starting point if low disaster exposure is your top filter.
