Disaster agency spokesman Sutopo Purwo Nugroho said 47 people were confirmed dead, 15 were missing and 14 had suffered injuries.

Hundreds of homes were badly damaged, with some completely flattened.

He said a La Nina weather system, which typically causes unseasonably heavy rains, could have contributed to the flooding.

Java, which should be entering the dry season, has been hit by torrential downpours in recent weeks.

"This June there's still heavy rainfall which is causing floods and landslides," Mr Nugroho said, warning La Nina was set to strengthen in the coming months, increasing the risk of disasters.

Indonesia and other parts of Asia had been affected by a strong El Nino, which brings drought and sizzling temperatures.

La Nina often follows an El Nino phenomenon.
