Fire in JB Marks
Fire in the twelve months to October 2026: 594 fire detections seen from space; 1,305 ha burnt in the 7 of those months with burnt area out. The most since 2012: 2018, 1,571.
Two readings from space. Fire detections are hot spots a VIIRS satellite saw as it passed, each about 375 m across, counted where they fall in the place: a big fire gives many, a short one between passes none. Burnt area is the ground that looks burnt afterwards, from Sentinel-3 at 300 m, in hectares. Neither is a fire report from the ground.

NOAA-20 carries the same instrument as S-NPP and passes about 50 minutes apart, so its count is a second reading of the same fires, not extra fires. “Land seen” is the share of the place’s land the burnt-area product saw often enough that month to tell.

How we worked this out
What we changed: we counted FIRMS’s detections (presumed vegetation fires only) by the 2026 ward their position falls in, and summed CLMS’s burned fraction times each pixel’s area over each ward; municipalities, districts and provinces are the sums of their wards.
Fire detections: we acknowledge the use of data and/or imagery from NASA’s Fire Information for Resource Management System (FIRMS), part of NASA’s LANCE (VIIRS 375 m, S-NPP and NOAA-20). Burnt area: generated using European Union’s Copernicus Land Monitoring Service information (Burnt Area 300 m version 4, DOI 10.2909/8fa58061-28ab-49bb-9b77-c26b50733e34), modified; this does not mean the European Union endorses us.
