We investigated the effect of fluid core resonance (FCR) on tidal strains based on 7.1 yr strain data obtained from a laser extensometer at the Rokko-Takao station, Kobe, Japan. After removing oceanic tidal loadings and atmospheric effects, tidal amplitudes for the K1 and Ψ1 constituents were determined to be 70 per cent and more than 400 per cent of the predicted amplitudes, without consideration of the FCR effect, respectively. By applying a theoretical equation, in which the FCR effect on the tidal strains was taken into consideration, the period of fluid core resonance (TFCN) and the reciprocal of the quality factor (Q-1) were determined to be 427.5 (+/-11.1) sidereal days and 2.0 (+/- 0.8) × 10-4, respectively. The TFCN obtained in this study is consistent with those determined in previous studies based on data on the Earth's rotation, gravity changes within the estimation error and the value of Q-1 is within 120-670 per cent of those determined by the previous studies.
