New classification method of volcanic ash samples using statistically determined grain types
Rina Noguchi, Hideitsu Hino, Nobuo Geshi +2
We developed a method to classify volcanic ash samples by introducing statistically determined grain types. Using more than 10,000 numbers of automatically measured grain data (par…
