Real-Time Seismograms

The following figures show seismograms recorded by the monitoring stations in the Geneva Basin area. These seismograms represent the development of ground motion (vibration velocity) over time, recorded at earthquake stations LULY1, LULY2, LULY3, CHALL, COLLE, FORET, SAVIG, SALEV und PERON within the past five minutes.

The times indicated on the horizontal axes correspond to Coordinated Universal Time (UTC). The time normally used in Switzerland is Central European Time (CET), which is one hour later than UTC. During Central European Summer Time (CEST), Swiss time is two hours ahead of GMT.

The vertical axes indicate ground velocities in microns per second (μm/s). To make small, locally occurring earthquakes more clearly visible, the seismograms are band-pass filtered (from 2 to 10 Hz) before being presented.
