Berliner Tageszeitung - Indonesia flood death toll rises to 41 with 17 missing

Hours of heavy rain caused large volcanic rocks to roll down one of Indonesia's most active volcanos into two districts on Sumatra island Saturday evening, while flooding inundated roads, homes and mosques.

"Data as of last night, we recorded 37 dead victims... But from this morning it has grown again, the figure reached 41 (dead)," Ilham Wahab, West Sumatra disaster mitigation agency official, told AFP.

Rescuers were searching for 17 still missing, three in Agam district and 14 in Tanah Datar, both the worst-hit areas of the flood and home to hundreds of thousands of people, he said.

Ilham could not confirm the number of locals evacuated because officials had encouraged "people to evacuate to relatives' places, which are safer" than tent shelters in heavy rains.

"We are focused on first, searching and rescuing the victims, second, protecting the evacuees, protecting the vulnerable people," he said.

Roads in the districts were turned into rivers, with mosques and houses damaged.

Heavy rains inundated neighbourhoods with muddy flood waters and swept vehicles into a nearby river, while volcanic ash and large rocks rumbled down Mount Marapi.

Cold lava, also known as lahar, is volcanic material such as ash, sand and pebbles carried down a volcano's slopes by rain.

- 'Have mercy' -

Authorities sent a team of rescuers and rubber boats to look for the missing victims and to transport people to shelters.

The local government set up evacuation centres and emergency posts in several areas of Agam and Tanah Datar.

The national disaster mitigation agency, or BNPB, said 84 homes, 16 bridges and two mosques were damaged in Tanah Datar, as were 20 hectares (50 acres) of rice fields.

Survivors recounted their horror when the flooding and rockfall began.

"I heard the thunder and the sound similar to boiling water. It was the sound of big rocks falling," housewife Rina Devina told AFP, adding that three of her neighbours were killed.

"It was pitch black, so I used my cellphone as a flashlight. The road was muddy, so I chanted 'God, have mercy!' over and over again," she said of her evacuation to a local official's office.

Indonesia is prone to landslides and floods during the rainy season.

In 2022, about 24,000 people were evacuated and two children were killed in floods on Sumatra island, with environmental campaigners blaming deforestation caused by logging for worsening the disaster.
