The fire started on 12 February 2019 in Ban Rai, Thailand, and satellites saw it burning for 40 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 64,257 hectares from heat detections, spread across 4 municipalities.
It is the 2th largest in Uthai Thani Province since 2016 (of 65 with a page). Number 2 in Thailand in 2019, of 385.
Union of 6 GWIS (Copernicus) perimeters: overlapping areas count once.
No official record is matched to this page to compare it with.
12 Feb 2019 to 23 Mar 2019: first and last day with fire on the page.
Satellites pass a few times a day and cloud or smoke can hide the fire: a lack of detections is not an official extinction. Each country’s emergency service declares a fire contained or out.
First day with fire seen by the satellites or the perimeter.
No official record is matched to this page, so the alert time and the cause are not known here.
VIIRS detections at 375 m. Most intense hotspot: 395 MW.
There is no official record to compare with. Each hotspot is a pixel detected in one satellite pass, not a separate fire.
Total radiative power on 12 March 2019; hotspots that day: 245.
Fire radiative power (FRP) measures the energy the fire gives off when the satellite passes. Added up by day, it compares intensity, not area.
Fire Weather Index (Canadian system) computed by WorldFires for the day the fire started. Consecutive days without rain before: 0.
This is an index computed from weather model data, not a measurement of the fire nor an official warning. Danger warnings are issued by each country’s authority. Emergency number and official warnings
High of 33.4 °C and minimum humidity of 36% on 23 March 2019; gusts of 44 km/h on 17 February 2019.
These are model values for a cell of about 25 km, not from a weather station: they may differ from what was measured on the ground.
This page’s change log has been kept since 24 October 2026: every night what it publishes is compared and the difference is logged. Anything earlier is reconstructed from each source’s date and marked as reconstructed.
Every night a snapshot of what the page shows is saved. If anything changes, it appears in the list as a log entry.
A version keeps the area, dates, name and official record; the area as it was logged (changes under 2% are not logged). The map, hotspots and weather always show today’s data.

Fire radiative power detected each day, in megawatts, and number of hotspots. The magenta bar marks the peak day.
It had gone 0 days without rain (1 mm or more) when it started. Rain came after the fire: 3.0 mm on 26 Mar.
76% of the perimeter overlaps earlier fires recorded since 2016: 47,571 ha in 2016, 4,455 ha in 2017, 308 ha in 2018. Part of it burned more than once, so the yearly figures add up to more than the 48,805 ha that had burned before.

This compares size, not location: both shapes are at the same scale, north up, centred on each other.
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.
Inside the perimeter there were about 0.20 hectares of built-up land and almost nobody lived there (GHSL 2020, 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.

It started with an FWI of 0.8, a minimum humidity of 75% and rain the day before. Fires in the area that started in weather like this since 2016: 1.
First rain (1 mm or more) after it ended: none in the following ten days.
Fires in the area that started in similar weather: 1. With fewer than 15 we give no figures: they would be more noise than signal.
This is a bank of analogues: it shows what usually happens, not what will happen. With fewer than 15 twins we give no figures. How we calculate it
It was considered over on 23 Mar, and on 26 Mar 3.0 mm fell. We do not know whether the rain or the firefighters put it out.

RSS Changes to this page With cross-checks and a citable version
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.
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.
