The threat of further flooding and landslides remains high in Agam Regency, West Sumatra, Indonesia, prompting continued emergency response efforts from central and regional governments. Authorities have extended the emergency response period as subsequent landslides continue to occur.
Emergency Response Period Extended
The Agam Regency Government extended the emergency response period due to ongoing landslides. According to the Head of Data, Information, and Disaster Communication Center of BNPB, Abdul Muhari, the latest landslides occurred within the three days prior to January 4, 2026.
Subsequent Landslide Threat Still High
BNPB has detected cracks in the upstream areas of Agam. Moderate-intensity rainfall lasting for extended periods still carries the potential to trigger additional landslides, Abdul stated.
120-Meter Landslide Occurred in Ngarai Sianok
A significant landslide occurred in Gebing Ngarai Sianok, Agam Regency, measuring approximately 120 meters in height and 15 meters in width. The landslide was triggered by prolonged heavy rainfall. Fortunately, no casualties were reported.
Heavy Equipment Deployed to Anticipate Landslides
The Sumatra River Basin Agency V Padang is deploying two heavy equipment units to Agam. One unit arrived on January 3, 2026, with another scheduled for arrival on January 6, 2026.
