2016 Sep 27	Rinjani	0	Lombok (Indonesia)		Info
Based on data from the Mount Rinjani National Park, BNPB reported that as many as 1,023 tourists were on Rinjani when it erupted on 27 September; officially only 464 people were registered to make the 3-day trek to the volcano and back. Officials began the evacuation of tourists that day. According to a news article, 44 trekkers had still not returned to the entrance points by 1 October. The Alert Level remained at 2 (on a scale of 1-4); the public was warned not to approach the crater within a 3-km radius. (reference #2432) Cited references #2432 Venzke, E., R.W. Wunderman, L.

Remark:

Our list of volcanic eruptions closely follows the database of eruptions of the Smithsonian's Global Volcanism Project (GVP), the internationally most recognized data source for volcanic eruptions, but also includes significant eruptive episodes or related volcano events. "Volcanic eruptions" are usually to be understood as sequences of individual eruptive episodes that can follow each other, or even overlap (if several vents are involved), and can last many years, decades or even longer. For example, the current activity of Stromboli volcano is understood as a single eruption that has been ongoing since 1934.
