Fig. 6From: Sedimentation process of ashfall during a Vulcanian eruption as revealed by high-temporal-resolution grain size analysis and high-speed camera imagingGSDs of the ash deposit obtained using laser diffraction. White circles represent data obtained by grain size analysis. Thick blue, orange, and green lines represent subpopulations #1, #2, and #3, respectively. The thin black line shows the synthetic GSD formed by summing the subpopulations. The collection time is described in upper right corner in each graphBack to article page
