A new area of fiber-optic Sagnac interferometer application is presented and discussed. The fiber-optic sensor described in the paperm in well-known classic FOG configuration, has been designed for a detection of the rotational seismic events. The basic system optimisation for a detection rotation only without cenversion for rotation ac give an advantage for this system in compare to other rotational seismometers, which calculate rotational events in indirect ways. The comparison of data from th described fiber-optic rotation seismometer and two antiparallel pendulum seismometers are also presented.
