BANJARNEGARA, Indonesia - Heavy rains in central Indonesia loosened soil and collapsed a hill, setting off a landslide that killed at least 20 villagers and left 88 others missing under piles of mud, officials said.

Residents of Jemblung village in Central Java province's Banjarnegara district said they heard a roaring sound followed by the rain of red soil that buried more than 100 houses Friday.

"The landslide looked like it was spinning down. I managed to rescue a pregnant woman but could not save the other man," said Subroto, who, like many Indonesians, uses only one name.

He said one side of the hill collapsed and then another. "In five minutes, there were three [major landslides] and they swept away everything," he said.

By Sunday Indonesia time, 20 bodies had been pulled from the mud and the wreckage of crumpled houses as hopes faded that the 88 missing people would be find alive, said Sutopo Purwo Nugroho, spokesman for Indonesia's Disaster Mitigation Agency.

President Joko Widodo was traveling to Banjarnegara, about 285 miles east of the capital, Jakarta, on Sunday to meet with survivors and about 570 residents who were evacuated to temporary shelters. Eleven injured villagers were hospitalized.

Nugroho, a spokesman for the National Disaster Mitigation Agency, said Saturday that some rescuers heard what sounded like calls for help coming from the debris but that they didn't have equipment to dig. "Mud, rugged terrain, and bad weather hampered our rescue efforts," Nugroho said.

Tractors and bulldozers were brought in.

"It was like a nightmare. . . . We suddenly heard a terrible roar and we were immediately fleeing from the rain of red soil," said Wahono, who survived with four family members. "Many failed, and they were buried in the ground."

Wahono, who also uses only one name, said he heard people screaming and pleading for help in the heavy rain and darkness. But he said he was unable to do anything other than run with his family to safety.

The landslide was the second in several days on densely populated Java island. Mud and rocks hit Central Java's Wonosobo district on Thursday, killing at least one villager.

Seasonal rains and high tides 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-prone plains close to rivers.
