Poco Ranaka, Stratovolcano and mountain in Flores Island, Indonesia

Poco Ranaka is a stratovolcano on Flores Island featuring two distinct summits, with the southern peak rising higher than its northern counterpart. The mountain is shaped by layers of hardened lava and volcanic ash that have accumulated over time.

This volcano formed through repeated volcanic activity that shaped the geological structure of Flores. In the late 1980s, a new lava dome emerged at the site, followed by an eruption in the following decade.

The name Anak Ranakah means "child of Ranakah", given to the lava dome that appeared on the volcano's slopes in 1987. The name Poco itself is the local Manggarai word for mountain, used for peaks across this part of Flores. Villagers below the dome live with the volcano's continuing activity, and in 2011 diffuse white plumes rose from Anak Ranakah without any ash being detected.

The summit area holds the lava domes Poco Mandasawu and Anak Ranakah, formed in 1987, so the final approach crosses loose volcanic rock and ash. No facilities or marked trails are documented on the mountain; walkers should carry water, food and sturdy footwear and check volcanic activity reports before setting out.

The highest point on Flores Island is located on this volcano, revealing how volcanic geology dominates the island's entire landscape. This elevation makes it a notable landmark for anyone traveling across the region.
