Indonesian rescuers are continuing their search for seven missing individuals four days after heavy rains triggered flash floods and landslides in North Sumatra province, killing 15 people, an official reported on Tuesday.

According to details, 11 fatalities occurred due to landslides in the Karo, Padang Lawas, and Tapanuli Selatan districts, while four others died in flash floods in the Deli Serdang district following Saturday’s severe weather.

Around 100 rescuers, alongside police and military personnel, are involved in the search efforts, but persistent rainfall has posed significant challenges. “It has been raining from afternoon till evening, making it difficult to locate the missing individuals,” Abdul said, noting that the search will continue until Saturday.

The floods and landslides caused extensive damage to homes, mosques, and rice fields. Road access to several villages has been cut off, and excavators are being used to aid the search operations.

The disaster agency has advised residents in North Sumatra to remain vigilant as heavy rainfall is expected in the coming weeks, potentially leading to further flooding, Abdul added.

Landslides are a common occurrence in Indonesia, particularly during the rainy season. Deforestation and illegal small-scale mining in remote areas often exacerbate the risk of such disasters.
