닐라산

Nila

성층화산 · Indonesia · 781m

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.

지질학적 요약

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