After 53 years in silent, starting from August 2017 Mount Agung showed an increase in activity. In the context of disaster mitigation efforts, the PVMBG-Geological Agency provides early warning in stages by increasing the activity status of Mount Agung from Level I (Normal) to Level II (Advisory) on September 14, 2017, from Level II (Advisory) to Level III (Watch/Standby), on September 18, 2017 and from Level III (Watch/Standby) to Level IV (Warning/Beware) on September 22, 2017. Mount Agung eruption began on November 21, 2017 and reached its peak on November 25-29 2017 where the ash column reached a height of more than 7000 m above sea level (more than 4000 m above the peak). This eruption did not cause casualties but there was some damage to the land and irrigation system, lava which hit sand and garden mines and some houses and volcanic ash which caused airport closure several days in Bali and Lombok.
In the last two months Mount Agung was still in a period of eruption marked by several small-scale eruptions. Eruptions in late June and early July 2018 slightly increased in intensity and caused airport closures in Bali, Banyuwangi and Jember. Mount Agung monitoring system is strengthened by collaborating with the USGS in the United States and IRD France. Based on the analysis of the latest monitoring data, it can be concluded that the activity of mount Agung is still unstable and small-scale eruptions may still occur at any time that cannot be determined. Indications for large-scale eruptions have not been observed. Current activity level of Mount Agung is at Level III (Watch/Standby) with the Estimated Zone of Danger within a 4 km radius of the crater.
