Mount Sinabung volcanic eruption and renewed activity

Overview

On August 31, 2026, Mount Sinabung in Sumatra erupted, sending a thick column of black volcanic ash approximately 3,500 meters above the peak. The eruption lasted for over an hour and was recorded with a maximum seismographic amplitude of 120 mm. Ash drifted primarily toward the east and southeast.

In response, the Center for Volcanology and Geological Hazard Mitigation (PVMBG) raised the alert level from Level II (Alert) to Level III (Siaga). Authorities established exclusion zones prohibiting activity within a 3-kilometer radius of the summit and a wider 6-kilometer restricted sector to the south-southeast. Falling ash has affected residents in the Karo Regency, prompting the distribution of face masks in areas such as Berastagi, Kuta Tengah, and Payung. The National Disaster Management Agency (BNPB) coordinated the evacuation of approximately 615 residents to emergency shelters in Sukatepu village.

By September 2, 2026, PVMBG reported renewed activity characterized by thickening black smoke, fire points at the summit, and continuous tremors. Rita Susilawati, head of PVMBG, warned that these signs indicate high levels of internal volcanic activity, suggesting that after a four-year period of dormancy, the volcano may be entering a new cycle of magma dynamics.

By September 5, 2026, the North Sumatra Regional Disaster Management Agency (BPBD) reported that approximately 201 families, or 650 individuals from Kuta Tengah Village, had sought refuge in Suka Tepu Village and the Koperasi Desa area. Residents from the 6 km red zone, including Kuta Rakyat Village, were evacuated to safe points in the Naman Teran District. To mitigate health risks such as acute respiratory infections (ISPA), BPBD has deployed masks, tents, clean water tankers, and mobile toilets, while coordinating medical escorts with health offices. Karo Police and Brimob personnel are also providing mobility assistance and shuttle services for evacuees.
