Safety from natural disasters depends on a combination of geographic location, geology, climate, and infrastructure. No completely safe country exists, but some experience significantly lower risk.
Switzerland, despite local hazards like avalanches in alpine regions, is among the safest due to few large earthquakes, hurricanes, or volcanic activity. Norway and Sweden similarly have low risk. Austria and Germany are also relatively safe.
Australia and New Zealand have earthquake, tsunami, and volcano risks in some areas but are relatively safe over broader regions. While New Zealand has high earthquake risk in some areas, national preparedness and response capacity is excellent.
Canada is relatively safe except for earthquake risk in western regions. North American interior (Texas, Kansas, etc.) also has significantly lower risk.
However, "safety" is relative. All regions may experience some form of weather-related disaster like extreme winter storms.
