A predawn landslide tore through Pasir Langu village on Mount Burangrang's slopes at 2 a.m. on January 24, 2026, burying 34-48 houses and a marine training camp under up to 8 meters of mud while residents slept. The disaster has claimed at least 85 lives, including at least 23 members of Indonesia's elite marine force who were conducting border patrol training, with search teams now in their 12th day manually excavating a 2-kilometer debris field using over 3,675 personnel, tracker dogs, drones, and heavy equipment despite unstable terrain.[1][2][7]

In late November 2025, rare tropical Cyclone Senyar dumped extreme rainfall on Indonesia's Sumatra island, unleashing catastrophic floods and landslides across the provinces of Aceh, North Sumatra and West Sumatra. By January 4, 2026, Indonesian authorities reported at least 1,177 deaths and 165 missing, with more than 3.3 million residents affected and around 1.1 million displaced across 52 cities and regencies. Economic losses exceeded 68.7 trillion rupiah ($4.13 billion), with 166,743 houses damaged along with hundreds of bridges, health facilities and schools. The same storm systems killed roughly 200 more people in southern Thailand and Malaysia, turning a regional weather anomaly into Southeast Asia's deadliest climate disaster of the year.
