The explosive eruption at the volcano persists.
Vulcanian-sized explosions continue to take place from the Ontake crater generating pyroclastic material in the form of lava bombs and dense grey-to-black ash emissions. The Volcanic Ash Advisory Center Tokyo (VAAC) detected ash plumes that rose to an estimated an 1,9 km altitude and extended to the north of the volcano. The Japan Meteorological Agency (JMA) reported that lava bombs were being ejected to an approx. distance of about 400 meters from the main crater over the past week.
From available surveillance cameras, a night-time glow continues to be observed from the summit vent associated with gas and steam emissions.
The warning bulletin states that ballistic impacts of volcanic bombs could affect an area of about 1 km distance from the main crater.
