Wildfires

NASA FIRMS (VIIRS)

Right now

The most recent data we hold from NASA FIRMS (VIIRS) arrived 4 minutes ago, and this point is not in it. We record detections, not passes: an absence is not proof that nothing is there.

Nothing else has been detected within 20 km in the last 24 hours.

Recorded by satellite 125 days ago.

A thermal anomaly is a snapshot of one satellite pass, not a record of a fire’s life: we cannot say whether it kept burning after that pass.

It is the 5th strongest of the 20 detections recorded within 20 km of this point since 9 May 2026. Another comparable one was recorded here earlier the same day. 6 more were recorded here in the fortnight before it.

What the source measured

NASA FIRMS (VIIRS) reported 118 fire pixels with a combined fire radiative power of 829 MW, at high confidence, 518 km from Darwin.

The 118 pixels cover about 16.5 km² — that is the footprint of the detection grid at 375 m resolution, not an estimate of how much land burned.

FIRMS does not report burned area, and neither do we.

Wind from SW at 9 km/h at 19:00 UTC, according to MET Norway.

How we know

One source: NASA FIRMS (VIIRS). Not yet confirmed by a second, independent source.

Our own score for this event is 54 out of 100.

This is our versioned heuristic index, not source severity or a calibrated probability. Urban PEI does not count unique people.

Wind: MET Norway Locationforecast, CC BY 4.0.

Computed under scoring rules v1. Rows carrying other versions were judged by different rules and are not directly comparable.

Under rules v1–v3, Critical for a wildfire measured only the radiative power the satellite saw, not the people near it; since v4 (1 September 2026) it also requires exposed population. This page keeps the word it was published with.

Physical priority index · v1. Heuristic priority, not calibrated probability, predictive accuracy or damage. The legacy data-support index combines assigned source support and field availability. Urban PEI is distance-weighted and does not count unique people; zero does not establish that nobody is present. Model cards.

Safety Information

If a wildfire is approaching: follow evacuation orders immediately. Do not wait to see the fire. Close all windows and doors, remove combustible materials from around your home, and have an emergency go-bag ready. Air quality can deteriorate rapidly even at distance from the fire front — monitor local air quality advisories.

Series begins 8 March 2026. Comparisons refer to that period only. Collection gap: 14-26 August 2026.

This data is aggregated algorithmically from scientific sources. Not a replacement for official emergency warnings.
