CVGHM reported that during January-8 April white plumes rose 10-15 m above the Anak Ranakah lava dome and seismicity decreased. On 9 April the Alert Level was lowered to 1 (on a scale of 1-4).

Geological Summary. The Anak Ranakah (Child of Ranakah) lava dome was formed in 1987 in an area without previous recorded eruptions at the base of the large older lava dome of Gunung Ranakah. An arcuate group of lava domes extending about 12 km west from Gunung Ranakah to Poco Mandosawa occurs on the outer N flanks of the poorly known Poco Leok caldera on western Flores Island.
