The Seismological Calibration Centre is equipped with electronic systems for the verification and calibration of seismic acquisition equipment, also on behalf of third parties.
The heart of the laboratory is the vibrating table, equipment for the precise calibration of seismic sensors (velocimeters and accelerometers in particular), completely designed and built by the staff of the Centre for Seismological Research of OGS.
The vibrating table is an instrument capable of reproducing oscillations programmed by the experimenter and simulating the effects of an earthquake.
The calibration of all the sensors of the monitoring networks is repeated annually, using both the indirect method (by sending a calibration impulse to the geophone on the remote station and analysing the response) and the direct method (carried out in the laboratory using a vibrating table).
