Jakarta: The search for 35 people who are still missing from flash floods and mudslides in Indonesia’s West Sumatra province continued, authorities said, as the casualties from the weekend disaster rose to 58.
Heavy rain on Saturday evening triggered flash floods, landslides, and cold lava flow – a mud-like mixture of volcanic ash, rock debris and water – in three districts and one town in West Sumatra province. By Tuesday, the casualties were at 52.
A search operation was underway on Wednesday as rescue workers combed through rivers and the rubble of devastated villages. The roads had transformed into murky brown rivers, and villages were covered by thick mud, rocks, and uprooted trees.
The cold lava flow, known by the Indonesian word lahar, came from Mount Marapi, one of Sumatra’s most active volcanoes. More than 20 people were killed when Marapi erupted in December. A series of eruptions have followed since.
The national disaster and management agency BNPB will focus the search for the missing people in areas near rivers and clean the main roads from the large rocks, debris, and mud brought by the floods, its head Suharyanto said in a statement on Wednesday.
Video shared by BNPB showed logs, rocks and mud strewn over roads in Tanah Datar district, with some collapsed bridges and houses.
Residents helped by local rescuers, police and military were cleaning houses and mosques from mud. In some settlements, excavators were deployed to remove large rocks and trees.
At least 249 houses, 225 hectares (556 acres) of land, including rice fields, 19 bridges and most of the main roads were damaged in three districts and one town.
Indonesia’s meteorology agency BMKG said it planned to try to mitigate heavy rainfall expected for the next week in West Sumatra by “cloud seeding” to prevent rains in the worst affected areas.
