a (black line) Vertical displacement obtained from the daily solutions of GNSS observations at Mizusawa from 2014 to 2021. (red line) Result of fitting a numerical function to the GNSS data based on the method of Tobita (2016). b (gray line) Residual gravity data observed at Mizusawa. (black line) The same but after the correction of free-air effects. The red curve represents the result of fitting Eq. (4) to the data
