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 shows the soil amplification of the seismic waves compared to a standard reference rock (with an average S-wave velocity in the shallower 30m, Vs30, of 1100 m/s): Values greater than 1 mean a higher amplification, values below mean a lower 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 of Switzerland's more than 2 million residential, commercial and industrial buildings.
