The earthquake risk map is based on an index that combines the expected number of fatalities with the estimated financial losses due to building damage. The values indicated always refer to an area of 2 x 2 kilometres. The earthquake risk is highest in the areas coloured dark red. The light-blue areas have a lower risk because there are relatively few people and assets in these locations. Even so, the damage to individual buildings in these regions could be devastating. An earthquake risk exists, therefore, throughout Switzerland.
