Luya fire, September 2024 Luya, Chachapoyas, Bongara
The fire started on 9 September 2024 in Luya, Peru, and satellites saw it burning for 6 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,347 hectares from heat detections, spread across 3 municipalities.
It is the 2th largest in Amazonas since 2016 (of 10 with a page). Number 13 in Peru in 2024, of 71.

Burnt area inside each municipality, from crossing the GWIS perimeter with administrative boundaries. The distance is from the town centre to the nearest fire: staying a kilometre away does not mean it reached the houses.
The weather day by day
ECMWF ERA5 reanalysis at the fire location, the standard reference for past weather, and the Canadian Fire Weather Index (the same system Copernicus uses), computed by WorldFires from that data. Days after the fire run until the first rain.

The smoke
CAMS · CopernicusOn 10 September 2024 the air beside the fire reached 54 µg/m³ of PM2.5. That day averaged 41: 2.7 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Luya fire last?
- GWIS (Copernicus) dates it between 9 September 2024 and 14 September 2024: 6 days between the first and last heat detection of the perimeter.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 2,347 hectares (23.5 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 3 municipalities: Luya (2,132 ha, 0.6 %); Chachapoyas (187 ha, 0.1 %); Bongara (43 ha, 0.0 %).
- What was the weather like?
- During the fire the temperature reached 22.6 °C, humidity dropped to 43 % and gusts hit 41 km/h. The fire danger index (FWI) reached 3, class Very low.
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Peru (geoBoundaries). It is not an official report.
Where to verify it
A satellite detection is not an official report. Final figures and the fire’s status are published by each country’s emergency service.

Does something look wrong on this page?
This page is built from satellite data and official records, and it sometimes gets things wrong: the wrong dates, the wrong town, two fires merged into one, or something that was not a wildfire at all. If you know this fire first-hand (you live nearby, saw it, fought it or reported on it), tell us what really happened and we will check it.

Where this data comes from
The perimeter comes from the Copernicus Global Wildfire Information System (GWIS), which rebuilds it from MODIS and VIIRS heat detections and publishes it under CC BY 4.0. It is not measured on imagery as in Europe, so it is an estimate. Heat detections come from the VIIRS sensors aboard Suomi-NPP and NOAA-20, distributed by NASA FIRMS at 375 m resolution. Municipal boundaries come from geoBoundaries ADM2 (Creative Commons Attribution 3.0 Intergovernmental Organisations (CC BY 3.0 IGO)). The area per municipality is computed by WorldFires by crossing the perimeter with those boundaries, so it may differ from each country’s official figure.
