Sakurajima , Caldeira Aira , Japan : Explosions were detected on 8 February.

JMA reported that an explosive eruption at Showa Crater (at Aira Caldera’s Sakurajima volcano) began at 1856 on 5 February and generated an ash plume that rose 1.3-1.8 km above the crater rim. Lightning was observed in the ash cloud, and incandescent tephra was ejected as far as 1.8 km onto the flanks. The Alert Level was raised to 3 (on a 5-level scale); it had previously been lowered to 2 on 25 November 2015. During an overflight the next day scientists did not see any significant changes to the crater; a plume obscured views of Minamidake summit crater. Sulfur dioxide emissions were 100 tons/day, which was the same level measured on 3 February.

Explosions were detected on 8 February. Based on JMA reports and satellite data, the Tokyo VAAC reported that during 8-9 February ash plumes rose to altitudes of 1.5-3.3 km (5,000-11,000 ft) a.s.l. and drifted E and SE.
