The island of Sulawesi was devastated by a powerful earthquake and a tsunami on September 28, which left a trail of destruction throughout the region.
More than 2,100 people have died as a result of the disaster, at least 2,500 are seriously injured and hundreds more remain missing.
Tens of thousands of homes have been destroyed and entire communities have been wiped out, leaving more than 330,000 people homeless or without adequate shelter; 200,000 of those survivors – around a quarter of whom are children – are now in urgent need of clean water, food, medical care and shelter.
