The 5 x 6 km Nila Island in the Banda Sea is comprised of a low-rimmed caldera whose rim is breached at sea level on the south and east and contains a 781-m-high youthful forested cone. Phreatic eruptions from the dominantly andesitic Nila, also known as Laworkawra, have occurred from summit vents and flank fissures in historical time. A 1932 eruption from a fissure that extended from the summit to the SE coast produced heavy ashfall that forced abandonment of Rumadai village.

|Nila Island, viewed here from off its northern coast, is the emergent summit of a stratovolcano that rises 3700 m from the Banda Sea floor. A submarine vent is located off the north flank immediately west of the small island of Nika. Gas bubbles were observed along the rim of the submarine cone in 1932, when an eruption occurred from a fissure extending from the summit to the SE coast.

|A fumarole plume (right-center) rises above the steep SE slopes of Nila volcano, also known as Laworkawra or Lawarkawra. A remnant of the rim of a 5-km-wide caldera forms the forested slope at the left. The 781-m-high summit above it is a post-caldera cone that fills much of the caldera and extends to the sea at the right. Phreatic eruptions from Gunung Nila have occurred from summit vents and flank fissures during historical time.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
