Intensity

The impacts of an earthquake on the earth's surface (i.e. on buildings, people, the environment and infrastructure) are described using a 12-point intensity scale.

The intensity of an earthquake depends on its location and is determined by its magnitude, the distance from the earthquake epicentre and the geology (subsurface).

One way the Swiss Seismological Service (SED) ascertains how and where earthquakes are felt is by means of an online questionnaire that the public can fill in.
