Oral presentation

A method of superconducting gravimeter calibration using earthquake signal is established. A set of observations of the superconducting gravimeter and the parallel broadband seismometer during an earthquake wave travelling are employed to verify the efficiency of system. The primary results is shown that the calibration precise is up to 0.5% in an events of earthquake. The calibration can be accepted in the tidal band since the well consistency of the Superconducting gravimeter in frequency and high precise of the broadband seismometer in a short interval.
