Natural-disaster risk in Sri Lanka

In Sri Lanka, the leading natural-disaster exposures are flooding, storms (hurricane/cyclone), extreme heat. The safest city for disasters is Kandy (safety 63/100). 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 Sri Lanka's disaster profile

Across the 12 Sri Lanka cities in our data, the three highest average exposures are flooding (4.3/5), storms (hurricane/cyclone) (3.6/5) and extreme heat (2.9/5). 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 Sri Lanka is flooding 4.3/5; storms (hurricane/cyclone) 3.6/5; extreme heat 2.9/5; tsunami 2.1/5; earthquake 1.8/5; drought 1.2/5; wildfire 1.0/5; extreme cold / winter 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.

Sri Lanka disaster exposure by type

flooding: 4.3/5 — high — plan, insure and check building codes for it.
storms (hurricane/cyclone): 3.6/5 — moderate — worth verifying for your specific neighbourhood.
extreme heat: 2.9/5 — low — a minor consideration.
tsunami: 2.1/5 — low — a minor consideration.
earthquake: 1.8/5 — negligible in our model.
drought: 1.2/5 — negligible in our model.
wildfire: 1.0/5 — negligible in our model.
extreme cold / winter: 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 Sri Lanka will drive. The safest single city in our Sri Lanka sample, Kandy (safety 63/100), is the natural starting point if low disaster exposure is your top filter.
