Bansgaon fire, April 2026 Khajni, Bansgaon, Sahjanwa
The fire started on 10 April 2026 in Bansgaon, India, and satellites saw it burning for 15 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 5,500 hectares from heat detections, spread across 3 municipalities.
It is the 13th largest in Uttar Pradesh since 2016 (of 14 with a page). Number 48 in India in 2026, of 58.

The weather it burned in
It had gone one day without rain (1 mm or more) when it started. Rain came after the fire: 1.3 mm on 26 Apr.
This area had burned before
94% of the perimeter overlaps earlier fires recorded since 2016: 2,110 ha in 2016, 1,871 ha in 2017, 3,106 ha in 2018, 2,758 ha in 2019, 1,044 ha in 2021, 2,755 ha in 2022, 685 ha in 2023, 1,624 ha in 2024, 1,121 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 5,156 ha that had burned before.

Burnt area inside each municipality, from crossing the GWIS perimeter with administrative boundaries. The distance runs from the point marking the centre of each area to the nearest fire: staying a kilometre away does not mean it reached the houses.
People and buildings inside the perimeter
GHSL 2025Inside the perimeter there were about 38 hectares of built-up land and about 17,000 residents (GHSL 2025, satellite-based estimate).
This is an estimate on 100 m cells, made from satellite imagery and census data: it does not mean that homes burned or that anyone was harmed. The perimeter also contains land that never burned. The GHSL 2025 epoch is a projection made from 2020 and earlier data.

The smoke
CAMS · CopernicusOn 8 April 2026 the air beside the fire reached 91 µg/m³ of PM2.5. That day averaged 67: 4.4 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Bansgaon fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 10 April 2026 to 24 April 2026 (15 days). The perimeter dates it from 10 April 2026 to 20 April 2026.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 5,500 hectares (55.0 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 3 municipalities: Khajni (2,360 ha, 4.3 %); Bansgaon (2,159 ha, 5.8 %); Sahjanwa (1,005 ha, 2.8 %).
- What was the weather like?
- During the fire the temperature reached 41.9 °C, humidity dropped to 10 % and gusts hit 56 km/h. The fire danger index (FWI) reached 78, class Very extreme.
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of India (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.

How we know this
- Perimeter: GWIS (Copernicus), rebuilt from heat detections rather than mapped on imagery.
- Dates adjusted with the VIIRS detections inside the perimeter, which said 10 April 2026 to 20 April 2026. 157 Suomi-NPP VIIRS detections on those dates.
- We have not matched this page with any official record.
- Weather: Copernicus ERA5 reanalysis at the fire location, in cells of about 25 km.
- Built-up area and population come from the JRC Global Human Settlement Layer (epoch 2025, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.
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 ADM3 (Open Data Commons Open Database License 1.0). 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.
