Vigorous steam plumes rise from vents near the summit of Ontake in central Honshu, Japan, on 9 November 1979. The first historical eruption began on 28 October and produced a 1.5-km-high eruption plume with ashfall to the NE. Intense gas-and-steam emissions with minor ash continued for several months.
