Volcano Rinjani is an active volcano on the Indonesian island of Lombok. It had started to give sings of new eruptions in October 2015. From 2 November onward the eruptions intensified.
The evolution of the eruptions can be verified with the long time series animation of Volcanic Ash & SO2 RGB from the AHI imager of Himawari-8, 02 November 2015 06:00 UTC–09 November 12:10 UTC.
It appears that the volcano only spewed ash (pink-coloured swaths being blown mainly in western direction). The RGB does not reveal any sign of SO2 (greenish or yellow signatures are missing).
In the observed period, the peak activity was on 5 November (Figure 1). It was reported that Rinjani was ejecting ash up to 14,000 feet making for hazardous conditions for aviation, as a result nearby airports were closed.
However, the GOES-R volcanic ash height product (derived using Himawari-8 AHI data) from the SSEC Volcanic Cloud Monitoring site indicated that the plume reached even higher heights of 10 km.
