Satellites are picking up an intense heat signature at the active Semuda wildfire in Indonesia, driven by the dry season conditions. The front has expanded across 300 hectares (741 acres) since it started on September 19, 2026, with space-based sensors recording 70 heat detections in the immediate area over the past 48 hours, illustrating the broad scale of the burning.
This incident unfolds during a broader national crisis, as 4,223,827 hectares have burned across the country so far in 2026, running 18% above the two-decade average.
In context
This wildfire has been burning in Indonesia for less than a day. So far it has affected roughly 300 ha (741 acres) — about 3.0 km².
Close to the tropics, fires tend to follow the dry season and are often linked to land-clearing rather than a single summer peak.
