Local subsoil

The effects of an earthquake at different places vary mostly due to the distance from and depth of the hypocenter of the earthquake as well as the local subsoil. The softer the ground, the more likely it is that damage will occur.

Which types of subsoil are encountered in which areas of Switzerland can be learned from the map of local subsoils. Fluvial valleys and lake shores are especially susceptible; the soft subsoil in these areas leads to shocks with up to ten times greater intensity.
