Officials in Indonesia say villagers are refusing to evacuate the slopes of Mt Merapi on the island of Java, one of the country's most active volcanoes.
There have been warnings of an imminent eruption.
People living within a 10km zone were told on Monday to leave the area. But they are reportedly reluctant to do so because of their crops and livestock.
The BBC reports Mt Merapi last erupted in June 2006, killing two people.
An eruption in 1994 killed 60 people, while about 1300 died in an eruption in 1930.
Indonesia is on the Pacific Ring of Fire, where the meeting of continental plates causes high volcanic and seismic activity.
