A new lava dome formed at the base of the large older lava dome of Gunung Ranakahin in 1987 and was named Anak Ranakah (Child of Ranakah). No previous historical eruptions were known from Ranakahin.
An arcuate group of older lava domes extending westward from Gunung Ranakah occurs on the outer flanks of the poorly known Poco Leok caldera on western Flores Island. Pocok Mandosawa lava dome, at 2350 m the highest point on the island of Flores, lies west of Anak Ranakah.
