The volcano continues to slowly extrude viscous lava, which results in occasional small to moderately sized pyroclastic flows (2-3 per day on average).

Unfortunately, it indirectly claimed another victim: heavy rains in recent days have appeared and produced numerous mud flows (lahars) that caused damages in various places, but also a victim: on 9 October, a lahar traveled through the Susuk riverbed near Tiganderket village on the western slope and hit a couple on a motorcycle while crossing the valley. It killed the driver who could not escape the muddy torrent, while his wife survived clinging to a tree trunk.

As to the volcano's activity, VSI reported a gradual decline in the tremor since July, but a slight increase of SO2 and CO2 output as well as inflation of the volcanic edifice on the other hand, which could indicate that a new batch of magma is rising within the volcano.

This could explain a larger explosion and pyroclastic flow that occurred on 13 Oct, producing an ash plume that reached 3 km height and a flow that traveled at least 3 km length.
