Rinjani eruption

by Robin Campion, Université Libre de Bruxelles, Bruxelles, Belgium

Rinjani Volcano (3726m, Lombok Island, Indonesia) in eruption. A lava flow is emitted on the flank of the intra caldera cone of Gunung Baru. Mild explosive activity at the vent is producing a 1500m high gas and ash plume, while a viscous lava is entering the 200m deep caldera lake. A hot spring on its shower release a plume of iron hydroxide precipitates giving a peculiar yellow color.
