The ash cloud above Mount Lewotobi Laki-laki on Monday was about four times taller than the one produced by an eruption there last month.

Australia's Volcanic Ash Advisory Center (VAAC) Darwin issued a red aviation warning about the volcanic ash plume, saying it rose to an estimated 19.2km altitude and is moving at 30 knots in a westerly direction.

Indonesia’s rumbling Mount Lewotobi Laki Laki has erupted with a column of volcanic materials as high as 11 miles into the sky and ash falling on villages.
