The effusive-explosive eruption of the volcano continues and no significant change in activity has occurred since the last update.
The lava flows on the south-southeast flank remain active and they have increased in length. The length of the lava flows is unknown and was not reported, but from available imagery (16 November) and compared to the last update image (4 July) seem to be longer.
Incandescent material is being ejected above Seloko Jongring crater and caused avalanches of material.
Explosive activity continues from the active crater with sporadic ash emissions that reached 12,000 ft (3,657 m) altitude.
The seismic instruments recorded 76 volcano-tectonic earthquakes.
The warning bulletin states that ballistic impacts of volcanic bombs and pyroclastic flows could affect an area of about 1 km distance from the main crater and 4 km on the SSE flank.
