Why do some farmers refuse to move to emergency shelters?

Thousands of people living in villages closest to the volcano have already been moved to emergency shelters. Many more are lining up by the side of the road waiting for trucks to take them to safety. But still there are a few farmers refusing to move. Without their crops and animals they have no income and cannot support their families so they’re waiting until the government offers financial help. Meanwhile, the mountain above them is becoming more active by the day. At least one village about three kilometers from the crater has been covered in a dusting of volcanic ash. One scientist told the BBC he now believed Merapi was in what he called the early stages of an eruption but he added "we cannot predict when it will reach its peak".
