Diaporama
Sakurajima volcano is known for its irregular (typically 1-2 per day) strombolian to vulcanian-type explosions which sometimes can reach considerable size and eject ash and bombs to several kilometers height and distance.
This semi-persistant activity has been going on since 1955, but fluctuates a lot in intensity in rhythms of typically weeks to few months.
Starting from late August, we try to list single explosions (at least those recorded by Tokyo VAAC and other sources). If you like to help us keep the table updates, please feel free to drop a message!
Here's what a typical (relatively strong) vulcanian explosion looks like (3 Oct 2013 Nov 19:33 GMT, or 4 Oct 04:33 local time):
