Sakurajima volcano appears to be at higher levels of activity, as the last week has seen an increased average number and size of eruptions. According to the latest USGS / Smithsonian report "explosions during the past week "often" produced plumes that rose to altitudes of 1.2-3 km (4,000-10,000 ft) a.s.l. and drifted NW, E, and SE." Many obseervations of ash plumes originate of analysis of satellite data and dedicated Volcanic Ash Advisory Centers (VAAC) around the world monitor them and transmit real-time information about hazardous ash plumes to aircraft and air traffic control centers. Such reports are often complemented by direct observations from pilots passing nearby.
Ash plumes from Sakurajima were observed by pilots on 5 and 6 March, the latter drifting SE at an altitude of 2.4 km (8,000 ft) a.s.l.
Sakurajima volcano in southern Kyushu, Japan, is one of the few volcanoes in the world with near persistent activity and typically produces 1-2 strombolian to vulcanian-style explosions per day.
