Flooding: Disproportionate amounts of water as a result of excessive precipitation. However, this remains within natural or human limits.
Extreme flooding: Damage caused by flooding. The water exceeds natural or human limits.

- gutters and drainpipes.
Rockslides: Large masses of rock come loose and fall on buildings.
Rockfall: Individual stones damage the walls of a building.
Landslides: Soil and rock slip down a slope and destroy buildings.

Fire

Lightning
Explosion and implosion
Crashing and emergency landing of aircraft and spacecraft or parts of such craft
Depending on the insurance policy, scorching damage up to a low limit. Scorching damage is caused by heat without fire.

The following don’t count as natural hazards (Art. 173 IOO, not available in English):

Damage caused by earthquakes and volcanic eruptions
Damage caused by subsidence, shifts in the earth caused by human intervention, or poor building sites

4. Are my home contents insured against natural hazard damage?

Home contents insurance is optional in most cantons. There are some exceptions:

Vaud
Nidwalden
Fribourg
Jura

Vaud and Nidwalden prescribe a cantonal fire insurance policy. In the cantons of Fribourg and Jura, you are free to choose the insurer.

Other insurable risks are also voluntary in the four cantons mentioned. This includes water damage and theft.

5. Damage due to natural hazards: deductible in Switzerland

The deductible is set by law for fire and natural hazards. It is 500 francs per insured event.

Important: if your insured sum is lower than the value of your home contents, you are underinsured. In that case, you will usually not be reimbursed for the full value of your home contents. If so, you will have to pay more than just the deductible.
