Sumatra's Floods Killed 604 People and Displaced 570,000. Jakarta Still Won't Call It a National Disaster.

At least 604 people are dead and 464 remain missing after floods and landslides tore through North Sumatra, West Sumatra, and Aceh, Indonesia’s National Disaster Mitigation Agency (BNPB) reported as of roughly 2 December 2025. Another 2,600 people were injured. More than 570,000 were displaced from their homes, with some villages still cut off entirely. ^{[1] [2]} Cyclone Senyar battered the three provinces between 19 and 28 November 2025. ^[3]

President Prabowo Subianto visited the affected areas in Aceh, North Sumatra, and West Sumatra on 1 December 2025. ^[4] Local leaders have called for a national disaster declaration. West Sumatra’s own provincial government has pleaded for the designation. Prabowo and his government have declined to classify the floods as a national disaster. ^[5] That status is the mechanism that unlocks additional national-level funding, personnel, and logistics for a response effort running on provincial budgets and donation links.

   BNPB’s toll reaches 604 dead and 570,000+ displaced. The national government has not declared an emergency.

Sumatra’s hillsides have spent years being cleared for plantations and mining. Climate scientists have described the pattern connecting deforestation to worse flooding and landslides for decades. A storm that might once have meant swollen rivers instead met slopes stripped of the root systems that used to hold them together. The weather caused the disaster. So did whoever signed off on the land-use permits.

In Indonesia, a national disaster declaration is not an automatic response to scale. It is a discretionary one. Local leaders say the criteria have been met. The presidency has toured the wreckage in person. The declaration that would move federal money faster than a photo opportunity has not been signed.

The cost of “not yet” is slower aid disbursement. Provinces are improvising rescue logistics on their own. A donation-link economy is standing in for the state’s own machinery. The generosity of ordinary people is not a substitute for the resources a national emergency designation exists to release. Declare the disaster.
