Barhat fire, April 2017 Barhat, Surajgarha, Dharhara
Out · last detection 13 Apr 2017, 07:16 UTC
The fire started on 7 April 2017 in Barhat, India, and satellites saw it burning for 7 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 20,090 hectares from heat detections, spread across 6 municipalities.
Number 2 in India in 2017, of 27.
The power measured by the satellite is low (22.6 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

Inside the perimeter there were about 1.4 hectares of built-up land and about 800 residents (GHSL 2015, 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.

How a twin is chosen
- Same area: fires that have already ended, less than 250 km from this one, since 2016.
- Same start: we compare the FWI on the first day, the minimum humidity that day and the run of days without rain before it. The slider sets how much they may differ.
- Only pages with final weather data (ERA5 reanalysis) calculated in the same way as this fire’s; agricultural and grass burns and pages with data under review are left out.
- Fires burning at the same time as this one (a week before or after) are left out: they share the same spell of weather and do not count as a precedent.
- They are sorted by similarity, and the outlines of the first five are drawn.

Frequently asked questions
- How long did the Barhat fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 7 April 2017 to 13 April 2017 (7 days). The perimeter dates it from 7 April 2017 to 12 April 2017.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 20,090 hectares (200.9 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 6 municipalities: Barhat (7,767 ha, 34 %); Surajgarha (4,670 ha, 12 %); Dharhara (4,641 ha, 16 %); Kharagpur (1,724 ha, 5.0 %); Lakshmipur (828 ha, 3.2 %); Chanan* (546 ha, 3.8 %).
- What was the weather like?
- During the fire the temperature reached 39.0 °C, humidity dropped to 12 % and gusts hit 47 km/h. The fire danger index (FWI) reached 52, class 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 7 April 2017 to 12 April 2017. 831 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 2015, 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.
