The possibility of detection of weak seismic waves in sea-ground interface by fiberoptic interferometric seismometer is experimentally demonstrated. High sensitivity of the seismometer to acceleration 10–7 m/s2 is provided by application of original multitun fiberoptical sensing element. Long term stability of the seismometer operation is provided by feedback control of the interferometer working point.
