Indonesian President Susilo Bambang Yudhoyono has warned that a volcano near Yogyakarta in Central Java province could erupt at any time.
People living on Mt Merapi's slopes have been warned to be prepared for evacuation, and officials have readied 300 vehicles for the operation.
In recent weeks, the 2,914-metre peak has again been increasingly active.
Mr Yudhoyono says it could explode or emit lava from its crater at any time.
"People do not need to panic but need to be alert and prepared to do anything for their own safety," he said.
Mt Merapi last erupted in 1994, killing 60 people.
An eruption in 1976 killed 28 people and made more than 1,000 homeless.
