Serua volcano (also known as Legatala) is one of the most active volcanoes of the Banda Sea. It forms a small 2x4 km wide island in the eastern Banda Sea, Indonesia. Andesitic Serua volcano is the tip of a stratovolcano rising 3600 m from the sea floor. It has a truncated cone formed by the Gunung Wuarlapna lava dome surrounded by a partial ring wall (somma wall) of the remnants of an older, collapsed edifice. Two old lava flows are visible on the east flank.
A permanent plume of volcanic gases is emitted from vents near the central dome (Gunung Wuarlapna), which forms the summit of Serua Island.
Active fumaroles are found in the area between Legatala and the NE part of the summit lava dome, where ground temperatures reach 97°C at 20 cm depth. Hot springs are found on the north beach.
