After several weeks of apparent calm, the awaited eruption of the volcano has begun early on Saturday morning (25 Nov 2017): Moderate explosive ash emissions have been creating a plume that has been rising 1.5-4 km above the summit crater of the volcano and drifting mainly to the south.

So far, the eruption is only moderate in scale and has not caused significant damage, and Indonesia's civil protection urges the population to remain calm and not panic. While Denpsar's airport remains operational, several (mainly Australian) airlines have already cancelled flights in and out of Denpasar.
According to observers and some webcam images, incandescence can be seen at the crater at night, and according to the volcanologists from PVMBG, the erupted ash is dark to black, likely from fresh magma. These observation suggest that by now the new magma ha indeed arrived at the surface.
Chances are that the eruption intensifies in the coming days, but just how much and how long it will last, and how dangerous it might become, is impossible to say at the moment.
Earlier on Tuesday, some small explosions had already occurred that generated white steam plumes with some ash that rose a few hundred meters, probably as a result of phreatic activity as the magma inside the conduit continued to approach the surface.
