An ash plume erupts from Tokachidake on 30 June 1962. A phreatic explosion on 29 June killed five sulfur mine workers and was followed by a magmatic eruption three hours later. It continued for 11 hours, producing a 12-km-high ash plume. Weak eruptions continued intermittently until September. Photo by Asahi Shimbun, 1962 (courtesy of Mario Yoshida, Hokkaido University).
