Hundreds of people on Pantar island have been forced from their homes by a volcanic eruption.
Mount Sirung in East Nusa Tenggara province began spewing smoke and dust about two
days ago. Hundreds of residents within one or two kilometres of the volcano had been moved
further away. No damage has yet been reported, but plantations at the base of the mountain
have dried up because of the eruption.

whose floor often contains one or more small lakes.
