Erdbebengefährdung

Compared to the rest of Europe, Switzerland is exposed to a moderate seismic hazard, with an evenly distributed earthquake activity, the canton of Valais being the region with the highest hazard, followed by Basel, Graubünden, the St. Galler Rhine Valley and Central Switzerland. No regions of Switzerland are not at risk of any earthquakes at all.

The seismic hazard indicates where within a certain timeframe and how frequently certain shaking is likely to occur. The assessment of the seismic hazard is based on knowledge of tectonics and geology, previous earthquake history, descriptions of damage caused and wave propagation models.
