Geography
Location Flores Island, Indonesia

Poco Mandasawu is a lava dome of Ranakah located in the south-central part of the island of Flores, Indonesia. It is the highest point of the island.

Lava dome Roughly circular protrusion from slowly extruded viscous volcanic lava

In volcanology, a lava dome or volcanic dome is a roughly circular mound-shaped protrusion resulting from the slow extrusion of viscous lava from a volcano. Dome-building eruptions are common, particularly in convergent plate boundary settings. Around 6% of eruptions on earth are lava dome forming. The geochemistry of lava domes can vary from basalt to rhyolite although the majority are of intermediate composition The characteristic dome shape is attributed to high viscosity that prevents the lava from flowing very far. This high viscosity can be obtained in two ways: by high levels of silica in the magma, or by degassing of fluid magma. Since viscous basaltic and andesitic domes weather fast and easily break apart by further input of fluid lava, most of the preserved domes have high silica content and consist of rhyolite or dacite.

Ranakah

Poco Ranakah is a volcano located in the south-central part of the island of Flores, Indonesia. Its tallest lava dome, Poco Mandasawu is the tallest mountain of the island. A new lava dome, named Anak Ranakah was formed there in 1987. The volcano erupted again in 1991. In 2011, diffuse white plumes were seen rising from Anak Ranakah Dome, although no ash was detected.
