Two cases of minor eruption of Mt. Asama are described. . A sample of ash collected on the occasion of the eruption on Aug. 4, 1935, consists of compact nuclei of rock fragment, a few tenth of mm in diameter, which is covered with a spongy mantle of aggregated fine ash particles. Possible causes of the origin of such a structure are suggested. As for the eruption of Aug. 17, 1935, an abnormal distribution of the intensity of audible sound within a narrow range of 10 km from the crater is described.
