Detection of gravitational geodynamic effects with gravitational-wave interferometers

We study the operation of the laser gravitational-wave long-base interferometer as a detector of tidal variations of the Earth's gravitational field. Empirical estimates of the low-frequency noise level of that detector, as well as an estimate of the magnitude of the detected signal accompanying the Earth's inner core oscillations have been obtained.
