Update 12/02 – 09:32 UTC : Based on reports in the Swiss press, and as predicted by Earthquake-report.com, NO damage has been inflicted.
Update 00:50 UTC : The Swiss seismological agency has been measuring a magnitude of 4.2. Also the Swiss seismological agency does not expect any damage from this earthquake. The epicenter was located in between the Zugersee and the Zurchersee (Zug lake and Zurich lake). Manual calculations have concluded that the hypocenter of depth of the earthquake was at a depth of 30 km, a reason why the earthquake hasn’t been harder felt above the epicenter.
Update : The earthquake has lasted 26 seconds but only a few seconds have been well felt by the people.
Update : Based on our experiences and if the current preliminary data are confirmed, we are convinced that NO serious damage or injuries is expected.
GFZ has recalculated the depth to a less dangerous 16 km and has decreased the magnitude to 4.0. Both main data indicators are becoming less dangerous.
