Villagers walk on ash left behind after Mount Kelud erupted last week, at Karangrejo village, 5km (3.11 miles) from the volcano, in Blitar, Indonesia's East Java province February 18, 2014. More than 56,000 people were forced to flee their homes and four people were killed when Mount Kelud erupted late on Thursday in East Java province, coating cities and airports as far as 500km (310 miles) away in a layer of ash and stranding thousands of passengers.
