Our local Indonesian partner, photographer and volcanologist Andi, spent a week at Raung to observe the volcano´s current explosive eruption.

On the 25th of February 2015, Andi reported us the following:
Over the last two weeks Raung has been spewing out lava fountains and explosions typical for Strombolian eruptions. During my visit there were many spectacular explosions, sometimes as frequent as occurring every 15 minutes. The loud detonation sounds and rumbling of the volcano could be heard up to 10-15 km away from the vent, as well as from Ijen crater. Harmonic tremors and regular gas venting are a steady occruence and seem to indicate that Raung might be building up a dome similar to the one in 2012.
The status alert remains at level 2 and so far no evacuation procedures have been initated for the many inhabitants of the land surrounding Raul volcano.
