Fig. 8From: Gravity changes associated with variations in local land-water distributions: Observations and hydrological modeling at Isawa Fan, northern JapanGravity amplitude ratio with respect to depth from the ground surface, ζ (Fig. 2). Dashed and solid lines represent the gravity attraction effect of soil water inside and outside the observation building—ain(ζ) and aout(ζ)—, respectively.Back to article page
