"We will have an emergency period for three months, May till August. The objectives are providing food, health care and shelter," Kalla told reporters. "The funds needed are about 1 trillion rupiahs ($100 million) ... for repairing homes and facilitating people's needs. This figure can change. It comes from the state budget and international aid."
