Frequency Switzerland
The Swiss Seismological Service (SED) records an average of between three and four earthquakes a day, or between 1,000 and 1,500 earthquakes a year, in Switzerland and its immediate neighbouring regions. Swiss citizens actually feel somewhere between 10 and 20 quakes a year, usually those with a magnitude of 2.5 or above. Earthquakes with a magnitude of at least 5 are expected to occur every 8 to 15 years. Larger earthquakes, with a magnitude of 6 or more, occur statistically only every 50 to 150 years in Switzerland and its neighbouring regions.
