The earthquake hazard map shows the expected horizontal acceleration caused by earthquakes within a certain period at a specific location.
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 local subsoil affects how strong the shaking from an earthquake will be at a particular location: the softer the subsoil, the more the seismic waves are amplified. This map illustrates the effect of ground amplification compared to a reference rock: higher values relative to the reference rock mean more amplification, lower values mean less amplification.
Earthquakes can only cause damage in places where people and property are present. The map of people and assets affected shows the spatial distribution and surface area of Switzerland's more than 2 million residential, commercial and industrial buildings.
