In the Swiss Meteorological Institution took over the seismological service in Switzerland. Since the SED is organised as a non-departmental entity under the direct control off the Vice President of Research, but it remains associated with the Department of Earth and Planetary Sciences. The SED publishes a seismic hazard map of Switzerland. Although it was only published in , the findings were included in SIA norm version. Installation of the Swiss strong motion network with acceleration sensors to detect strong ground movement.
Until , 59 sensors get installed on the open field and 34 sensors are built into in dams. The law came into effect on March 29th and outlined the following tasks:.
Using a transportable seismometer by De Quervain and Piccard an aftershock was recorded in the Wallis region for the first time, allowing the creation of precise estimates of traveltimes and velocities of the P and S waves. A universal seismometer developed by Alfred De Quervain and August Piccard and weighing 21 tonnes is put into operation at the earthquake monitoring station in Degenried, Zurich.
This means that for the first time all three components of movement during an earthquake northβsouth, eastβwest, vertical can be recorded simultaneously.
Moreover, the seismometer is also capable of registering both strong earthquakes of distant origin as well as weaker earthquakes in closer proximity. Rossi and Forel develop a macro-seismic scale with ten degrees of intensity, sometimes referred to as "Swiss-Italian Scale". On the occasion of the 61st annual meeting of the Swiss Society of Nature Sciences in Bern the Erdbebenkommission earthquake commission is established with its central office in Bern initiated by F.
