Ink: On Tokachi-dake, from Nihon Hyakumeizan (One Hundred Mountains of Japan) by Fukada Kyūya (1964):
Today, the sulphurous smoke vents not from the main crater but from the so-called New Crater that opened on May 24, 1926. The sudden explosion overthrew the crater wall, sending its debris and volcanic detritus cascading downslope in all directions. Fed by melting snowfields, the resulting mudflow cut a swathe of destruction for twenty-eight kilometres, burying homes, devastating countless fields, and snuffing out one hundred and forty-four lives.
