Fig. 3From: Influence of particle aggregation on the tephra dispersal and sedimentation from the October 8, 2016, eruption of Aso volcanoPlume dimensions as sketched from images at a 01:55, b 01:58, c 02:01 and d 02:05 on October 8 from the trial operation of WITH radar observation images (Weathernews Inc. 2016). The strong and weak reflectivity of the radar are shown by orange and light blue colors. The summit area covered by proximal fallout and pyroclastic density current deposits is shown in gray. Black and white bold numbers denote isomass (g/m2) and maximum clast contours (mm), respectively, which are equivalent to those of Fig. 2Back to article page
