Abstract
  • A new tiltmeter, based on the technology far building a space-borne high-sensitivity accelerometer and manufactured at IFSI CNR, has been operating during several years in the INFN Gran Sasso underground laboratory. The results of the analysis of a three-year data set, processed with the program package ETERNA, to estimate earth tidal parameters are reported. For the best series of data (1998) 1 tide measurement accuracies are: 0.5-1% far the M2 (lunar principal) amplitude and 3-4% far the 01 (lunar declination) amplitude. The tiltmeter installed at a depth of 1400 m shows no clear evidence of meteorological effects. Observed tidal parameters are compared with theoretical tidal parameters predicted far a non-hydrostatic inelastic Earth model and demonstrates good agreement for the M2 component. Due to the high accuracy of the tidal components prediction (better than 1 %) tidal measurements were used to estimate the long-term stability of the instrument response. (literal)
