During 26 December 2009-9 January 2010, a visitor to Sakura-jima observed and photographed Strombolian and Vulcanian explosions from Showa crater.
Based on information from JMA, the Tokyo VAAC reported that during 20-26 January multiple explosions often produced plumes that rose to altitudes of 1.2-2.4 km (4,000-8,000 ft) a.s.l.
and drifted NE, E, SE, and S.
On 23 January, a pilot reported that an ash plume drifted SE at an altitude of 1.8 km (6,000 ft) a.s.l.
