Workers stand near a Citilink airplane covered with ash from Mount Kelud at Adi Sucipto airport in Yogyakarta February 14, 2014. Mount Kelud volcano erupted late on Thursday night on the heavily populated Indonesian island of Java, sending a huge plume of ash and sand 17 km (10 miles) into the air and forcing the closure of three airports. Mount Kelud is 140 km south of Indonesia's second biggest city Surabaya, a major industrial centre. The cloud from the eruption was seen as far as 9 km to the west, and forced the shutdown of airports at Surabaya and the cities of Yogyakarta and Solo.
