Batu Tara volcano 23-26 Nov 2015During a 3-days expedition to the island we stayed on Batu Tara from 23-26 Nov: the volcano's activity was characterized by mild, ash-rich strombolian eruptions at intervals between 10-30 minutes alternated / interrupted by much more powerful vulcanian-type explosions that produced shock waves and ejected dense columns of tephra (ash, blocks and incandescent lava bombs) in a single, cannon-shot like explosion.
