United Nations aid agencies are to meet in Geneva to plan humanitarian relief for Indonesia following the earthquake.
The agencies say much more aid will be needed to help those hit
More than 4,600 are now thought to have been killed, and many more are in need of shelter, food, water and clothing.
The aid agencies, including Unicef, the World Food Programme, the World Health Organization and the International Red Cross, have already begun distributing some relief supplies.
But they say much more will be needed to help the thousands hit by the quake.
A United Nations emergency team led by the World Food Programme is already on the ground in Java.
It will assess the humanitarian situation in the wake of the earthquake and report to the agencies due to meet in Geneva on Monday.
Food and tents
Already, however, it is clear that the needs are enormous. Thousands of people have lost everything. Above all they need food and shelter.
The World Food Programme has begun distributing emergency food rations and the International Red Cross has handed out 2,000 tents, with 8,000 more on the way.
Unicef has despatched water tanks and school tents and supplies - a reminder that the damage caused by the earthquake will not be repaired overnight.
Many children will be learning their lessons under tarpaulin for months to come.
Immediate needs also include field hospitals and medicines.
The agencies meeting in Geneva will be looking at just what they have available in the wake of the huge demands made on their supplies following the Asian tsunami and the earthquake in Pakistan.
They will be working out how to get the supplies to Java as quickly as possible.
