Officials in Indonesia say supplies are not reaching earthquake survivors fast enough.
Water, tents, stoves, cooking sets, and medical supplies have started arriving in areas devastated by Saturday's 6.3 magnitude quake.
But, officials say the supplies aren't enough.
The Indonesian President says there's a "lack of coordination" in aid and is urging government officials to "be more agile".
The quake killed more than 4,300 people and left 220,000 homeless.
Activity at nearby Mount Merapi Volcano has trippled since the quake.
One volcano expert says a large eruption is still possible.
