Sakurajima volcano (Kyushu, Japan): powerful vulcanian explosions
Thursday May 24, 2012 11:28 AM | BY: T
Sakurajima volcano on Kyushu, Japan, remains in a state of elevated activity. During the past week, strong vulcanian explosions from the Showa Crater often occurred multiple times per day, and generated tall ash plumes reaching 4 km altitude. A small pyroclastic flow reaching 300 m length occurred during an explosion on 21 May.
Tokyo VAAC often reported plumes up to 1.8-3.7 km height during 16-20 and 22 May, and pilots observed ash plumes during 16-17 May that rose to altitudes of 2.7-4 km (9,000-13,000 ft) a.s.l. and drifted E and SE.
Very small eruptions were also reported from the second crater Minami-dake on 18 and 19 May.
