Active fire and thermal-anomaly detections from NASA FIRMS over the past 24 hours (VIIRS 375 m + MODIS 1 km), split into low, nominal and high confidence bands. Circle size scales with fire radiative power. IMPORTANT: these are thermal anomalies, not confirmed wildfires -- gas flares, industrial heat, active lava and agricultural burning all register identically, and the single strongest detection on a given day is often a volcano. Detections are limited by cloud cover and satellite overpass, so a blank area means nothing was detected, not that nothing is burning. Click any detection for its sensor, confidence, radiative power and acquisition time. For page weight the map draws only the strongest detections by radiative power (max_inline_features); the layer toggles show how many of each band are drawn, and the complete set is in the cached GeoJSON.
