By Rhiannon Wilson September 16, 2026

Is Mount Rinjani an active volcano? Mount Rinjani is a very active stratovolcano set at 3,726 metres above sea level in Lombok, Indonesia. A huge blast formed a huge 6-by-8-kilometre crater on Indonesia’s second-highest peak. However, a moon-shaped crater lake called Segara Anak now fills this mammoth crater. Geothermal action also warms the lake’s vibrant turquoise waters beneath the surface.

Is Mount Rinjani an active volcano? The clearest proof that Mount Rinjani is an active peak is the presence of Gunung Barujari. It is a small active volcano inside the crater lake. Over the last few years, the volcano has had many explosive eruptions that have sent ash clouds up to thousands of metres into the air.
