Serua Volcano is located in the eastern Banda Sea, Indonesia. Serua Island is 4 x 2 km in size. Serua volcano contains a truncated cone surrounded by a somma wall. Two old lava flows are visible extending in an easterly direction.

A permanent plume of volcanic gases is emitted from vents near the central dome (Gunung Wuarlapna), which forms the summit of Serua Island.

Basaltic lavas cover the slope of Legatala volcano. Tuff-layers and mudflows are well exposed along the north shore. The area between Legatala and the hill northwest of this active cone contains fumaroles. The ground has a temperature of 97°C
at 20 cm depth. Hot springs occur on the north beach. The composition is enriched by seawater.
