The eruption of Indonesia's Mount Lewotobi Laki-Laki was seen from space, with plumes of smoke and ash being thrown into the atmosphere. The volcano erupted at 5.35pm on Tuesday (local time), spewing ash 11km into the air, leading to cancelled flights out of Denpasar and an entire nation on high alert. Pictures showed clouds and ash engulfing nearby villages up to 93km away, while the eruption itself could be seen from space, according to Weatherzone.

They included domestic routes to Jakarta and Lombok as well as others to Australia, China, India, Malaysia, New Zealand and Singapore. The ash is made up of small pieces of rock, crystal and glass. If a plane were to fly through it, it could cause serious erosion to the body of the aircraft. The glass particles can also melt inside the engine, blocking the airflow and causing the engine to stall when it resolidifies. Recent rumblings The volcano's eruption follows significant volcanic activities, including 50 in two hours, up from the average eight to 10 activities per day. The 1584-metre twin volcano erupted again yesterday morning, spewing a 1km ash cloud, officials confirmed.
