The eruption continues. Ash emissions have decreased recently, with column heights ranging between a few hundred to 2000 meters. On the other hand, mild to moderate strombolian activity from the Barujari cone and the effusion of a new lava flow have been stable and seem to be going on strongly.
This apparent change in eruptive style could be due to a decreasing phreatomagmatic component (water mixing with magma) in the eruption.
According to local press, the explosions from the vent reach heights of (only) 50 meters and Gede Suantika, head of the Center for Volcanology and Geological Hazard Mitigation, who is also quoted to say that the eruption is likely to last 3 if not 6 months. On the other hand, in a report from a few days ago, strombolian explosions were mentioned to reach 750 m height.
Active lava flows are advancing to the north and east of Barujari cone. According to the latest estimate by Indonesian scientists, the total volume of lava erupted so far is approx. 4.5 million cubic meters. A significant part of this volume has entered the Segara Anak crater lake, which has risen by approx. 50 cm and led to an an increase of the outflow rate of the Koko Putih river, whose temperature also increased from 21 to 39 deg C.
A significant hazard is possible if the increased water outflow results in a (sudden) larger breach of parts of the containing wall at the river exit and produces a flash flood. This would put villages along the banks of the river further downslope, such as Desa Sajang and Obel Obel in danger. BNPB (Indonesia's Civil Protection) recommends local people to keep distance from and avoid all activities at the Koko Putih river.

Ash plume over Lombok island this morning (NASA / MODIS)
The eruption of the volcano continues to produce intense ash emissions. However, to the great relief of travelers to and from Bali, the strong easterly winds that had swept the plume over Bali during the past days, forcing the Denpasar International airport to shut down, have ceased and given way to weak southerly and northerly winds, thus allowing the airport to reopen. ...

Ash plume from Rinjani volcano drifting over Bali today (MODIS / NASA)
The eruption has intensified a lot over the past few days. Activity takes place from a lateral vent on the Barujari cone inside the volcano's caldera, producing continuous ash emissions and feeding a new viscous lava flow. The lava flow has been advancing more than 500 m in two lobes towards the NE. ... Lees alle
