Fig. 8From: Rheological properties of halloysite soil slurry: a case study of weathered tephra involved in a shallow landslide triggered by the 2018 Eastern Iburi earthquake in Hokkaido, Japan(a–c) G′, G″, and tan δ of slurry of moist soil with respect to shear strain at a solid concentration of 34.8 wt% with oscillatory frequency of a 0.5, b 1.0, and c 10 Hz. The crossover strain decreases with increasing frequency. d Summary of the crossover strain for each frequency with respect to water content. Natural moisture content is also shownBack to article page
