At Rinjani, on the Indonesian island of Lombok, the activity continues with explosions producing small ash plumes, which concern only the caldera. They are no longer identified by the satellites (Modis), nor commented on by the VAAC Darwin.
By cons, News.com.au, in his article of November 27, reported that a series of flights from Australia towards Denpasar / Bali had to turn back, and Virgin Australia canceled its flights during of the night, and this "although the ash cloud is currently smaller than the one experienced recently, but generates flight conditions that may change" according to the spokesman for Jetstar.
These conditions could continue during the month of December due to development of the monsoon; the winds could push the ash towards the island of Bali, according to the Australian Bureau of Meteorology.
The Rinjani National Park remains optimistic and plans to reopen on 1 December 2015.
In Sinabung, activity remains unchanged, with growth of the dome / lava lobe always impressive. Its permanent alimentation increases the risk of collapse and associated pyroclastic flows.
