JAKARTA — Two landslides triggered by heavy rain in Indonesia left at least 11 dead and 18 injured, officials said Sunday, according to the AP.

The second landslide in Cihanjuang village in the Sumedang district of West Java province occurred as rescuers were still evacuating people following the first disaster on Saturday, said National Disaster Mitigation Agency spokesman Raditya Jati. Rescuers were among the victims, he said.

"The first landslide was triggered by high rainfall and unstable soil conditions. The subsequent landslide occurred while officers were still evacuating victims around the first landslide area," Raditya said.

The death toll was preliminary as of Sunday morning, Raditya said, adding that potential rain and thunderstorms through the day may hamper rescue efforts.

The rain stopped on Saturday night. A bridge and roads were blocked by the landslides as authorities struggled to bring in heavy equipment to clear the debris.

Seasonal rains and high tide in recent days have caused dozens of landslides and widespread flooding across much of Indonesia, a chain of 17,000 islands where millions of people live in mountainous areas or near fertile flood plains close to rivers.

President Joko Widodo in October warned Indonesia that heavy rains from the La Nina weather system could trigger flooding and landslides, affecting the nation's agricultural output.

A La Nina pattern is characterized by unusually cold temperatures in the equatorial Pacific Ocean.

Indonesia frequently suffers floods and landslides, particularly during the rainy season from November to March, a situation often worsened by the cutting down of forests. — Agencies
