The Japan Meteorological Agency (JMA) reported that flight observations over the volcano confirmed no new craters.
Stronger-than-usual vulcanian-type explosion occurred at the volcano today that generated a dense dark ash plume, which reached approx. 6,000 ft (1,828 m) altitude and drifted SE.
Blocks were ejected as far as 800 m away from the crater, but some of the incandescent lava bombs reached 1,300 m ballistic trajectory this night as can be seen in the image.
In addition, the activity is accompanied with a strong glow from the Otake crater that suggesting rise of flux of magma within the volcano.
The warning bulletin states that ballistic impacts of volcanic bombs and pyroclastic flows could affect an area of about 2 km distance from the main crater.
