A scientist from the Volcanological Survey of Indonesia makes theodolite measurements along the N rim of the 5-km-wide Segara Anak caldera of Rinjani on Lombok Island. The lobate lava flow entering the lake at the lower left was erupted in 1944 from a vent on the NW flank of Gunung Barujari. Photo by Sumarna Hamidi, 1973 (Volcanological Survey of Indonesia).
