Fig. 6From: Temporal change of near-surface shear wave velocity associated with rainfall in Northeast Honshu, JapanOne-dimensional model for estimating the travel time increment. From Fig. 5a, for a level VI rainfall with a rainfall total of about 100–200 mm, the variation of volumetric water content ∆θ and variation of shear wave slowness ∆S can be estimated as approximately 20–40% and 4–10×10−3 s/m, respectivelyBack to article page
