Abstract

We performed large scale experiment to measure the falling velocity of volcanic material from Sakurajima volcano by using PARSIVEL. The PARSIVEL is laser-optical based disdrometer and measures size and falling velocity of the grains. Volcanic materials from Sakurajima volcano were fallen from 16 m of height, and their size and falling velocity were measured by the PARSIVEL. The experimental results provide the relation between the size and falling velocity as v = 5.900D0.530. This equation well replicates the experimental results than that in previous studies.
