Fig. 4From: 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, JapanTemporal evolution of yield stress for slurry of dried soil (solid concentrations of 41.8 and 40.6 wt%). The yield stress decreased rapidly in the first few hours and then remained constantBack to article page
