Last 2 hours

This image shows the last 2 hours of waveforms recorded across Switzerland. Shown are the vertical component from all the broadband stations operated by the CHNet. The sampling rate is 40 or 50 samples per second (BHZ channels). Stations are sorted in alphabetical order. The instrument response is first de-convolved, then band-passed between 30 s and 15 Hz. The units are bandpassed ground velocity, mm/s. Automatic high frequency detections (local Bear picks) which are used by the Seismic Network to identify earthquakes are included in red, if manual picks are available, they are shown in blue (P-picks) and green (S-picks). The image is updated every 150 s. This view can be used to observe seismic sequences as they are occurring.
